Pollinates many species of flowers, such as the chaparral flora of California. The chaparral flora has a large variety of species that have adapted to Anna's hummingbirds. These species of plants have developed winter growth and flowering to fit the breeding and feeding patterns of C. anna. These species, along with others, have evolved directly alongside Anna's hummingbirds.
Hummingbirds are the only birds that have adapted to fly backward and forward. Their wings can beat incredibly fast. In fact, when hummingbirds hover, their wings can beat from 22 to 72 times per second. This rapid motion causes them to expend most of their energy in flight; to make up for this nutritional deprivation hummingbirds can consume half of their body weight in food per day. Most species of hummingbird migrate during seasonal changes; however, Anna's and Allen's hummingbirds are the only two species that remain in the United States and Canada year-round. Calypte anna is the largest hummingbird that inhabits the west coast.
Perception Channels: visual ; tactile ; acoustic ; chemical
The Anna's Hummingbird population has been spreading and growing since the 1950's. They have expanded north and east from their original habitat. The flowers and feeders of suburban gardens have enabled them to extend into these different regions. Calypte anna are very common within most of their range; thus, there are regular sightings. In addition, they adapt well to suburban areas.

There are no negative impacts of Anna's hummingbirds.
Calypte anna has four sources of food: nectar from flowers, sap from trees, sugar-water mixes from feeders, and very small insects and spiders. Anna's hummingbirds are equipped with long, narrow bills and have a body adapted to hover over flowers. These two features allow them to easily extract nectar. While the bird is hovering over the flower it extends its tongue and inserts it into the flower. Calypte anna is most attracted to long, tubular flowers, with a red, orange, or violet hue. Some common hummingbird flowers include: azaleas (Rhododendron arborescens), fuchsia (Fuchsia arborescens), scarlet morning glory, honeysuckle (Lonicera sempervirens), and impatiens (Impatiens balsamina). However, C. anna feeds most frequently on: chaparral current (Ribes malvaceum), fuchsia-flowered gooseberry (Ribes speciosum), great-berried manzanita (Arctostaphylos glauca), monkey-flower (Diplacus longiforus), pitcher-sage (Salvia spathacea), California fuchsia (Epilobium), western columbine (Aquilegia formosa), and Indian warrior (Pedicularis densiflora). Apart from flowers, Anna's hummingbirds find food in the air by capturing flying insects or eating insects trapped in spider webs. They also use holes in trees to extract sap.
Animal Foods: insects
Plant Foods: nectar; pollen; sap or other plant fluids
Primary Diet: herbivore (Nectarivore )
Calypte anna breeds along the western coast of North America. The breeding range stretches from British Columbia through Arizona to the western edge of New Mexico. However, the non-breeding range is expanding. This range extends from the Alaskan coast to northern Mexico.
Biogeographic Regions: nearctic (Native )
Calypte anna have made their home in open woods, shrubs, gardens, and parks. During breeding season they are restricted to California and a habitat separation is established between males and females. During this time males typically move to more open habitats including canyon sides and hill slopes. Females, on the other hand, live in trees, including evergreens and oaks. Anna's Hummingbirds also experience different habitats with the changing seasons. During the summer months they move to higher elevations, and in winter they move to lower altitudes.
Habitat Regions: temperate ; terrestrial
Terrestrial Biomes: forest ; scrub forest

Anna's hummingbirds are medium sized, stocky hummingbirds. They are sexually dimorphic. Males and females both have a bronzy, green dorsal area that is glossy in appearance and a dull, gray ventral region. They have a medium length bill and a broad tail. Male C. anna have a brightly colored rose throat area and crown and a dark tail. Females are generally a dull mixture of gray/white or gray/brown, but may have a patch of metallic red or purplish feathers in the center of the throat area. The tail, tipped with white, is metallic green in the center with the exterior tail feathers darkening to black. Juvenile male and female birds both resemble adult females but there are some slight variations. Immature males have brightly colored feathers on the throat and crown and a less rounded tail, while young females are a pale brown and possess no metallic colored feathers on the throat region.

Calypte anna has many predators including western scrub-jays (Aphelocoma californica), American kestrels (Falco sparverius), greater roadrunners (Geococcyx californianus), and curved-billed thrashers (Toxostoma curvirostre). As a response to these predators, C. anna has developed two primary defense mechanisms. First, when a predator attacks a nest the female will mob the assailant. She will do this by hovering in front of the invader, beating her wings rapidly, and attacking the head and back. The second mechanism is to avoid low lying food sources, C. anna prefer high feeders and flowers.
Known Predators:
Male and female C. anna only come together to mate. Females are responsible for building nests, incubating the young, and rearing the brood. The seasonal winter rains start mating season, and it is during this time that males move into their breeding territories and females start the nest building process. The nest is bound together with spider webs and is lined with soft material such as plants, feathers, or hair. The outside of the nest is draped with bark, dead leaves, lichen, or paint chips, in an attempt to camouflage. The actual mating ritual commences when a female enters a male's territory. After the male spots the female he does a series of dives in the air and begins to chase her. During this chase, the female leads the male toward her nesting area and perches. During copulation the female spreads her tail, twisting it slightly downward and to the side. In order for fertilization to occur, the male must mount her back. During this time, he may seize her crown feathers with his bill and twist his abdomen and tail down her side. Copulation lasts 3 to 5 seconds.
Mating System: polygynandrous (promiscuous)
The breeding season commences between November and December and continues until sometime between April and May. During this season C. anna can have two broods. Each brood consists on average of 2 white, elliptical eggs, which are laid one day apart. Females incubate the eggs for 14-19 days, and chicks are in the nest an additional 18 to 23 days. The hatchlings are altricial, barely resembling the adult form. Their eyes open on the fifth day after hatching. When the hatchlings are six days old they are fully covered with down. After the nesting period the young remain dependent on the mother for a few additional days, but within one or two weeks they achieve total independence. There is no male parental care. Interestingly, immature C. anna start to show territorial behavior when they are quite young. After leaving the nest, Anna's hummingbirds have a tendency to remain in pairs, usually siblings. However, by fall most young C. anna separate and maintain their own territory.

Anna's Hummingbird (Calypte anna) is a year-round resident along the Pacific coast of North America, breeding north to British Columbia and east to Arizona. These hummingbirds are abundant in open woodlands, chapparal, scrubby areas, and partly open situations, as well as in deserts, especially in winter. They often forage in gardens and parks. They ascend to montane regions in the summer postbreeding season to forage in high mountain meadows.
Nesting may begin in December. In the male's courtship display, he hovers in mid-air giving a buzzy song, then flies much higher before diving steeply and rapidly toward the female, making a loud explosive popping sound at the bottom of his dive. He may also buzz back and forth in front of the perched female in short flights. Detailed analyses of male displays revealed that after powering the initial stage of the dive by flapping, males folded their wings by their sides, at which point they reached an average maximum velocity of 385 body lengths. This is the highest length-specific velocity known for any vertebrate. They then spread their wings to pull up and experienced centripetal accelerations nearly nine times greater than gravitational acceleration. This acceleration is the highest reported for any vertebrate undergoing a voluntary aerial maneuver, with the exception of jet fighter pilots. Displaying Anna's Hummingbird males produce both a vocal song and a dive-sound (made with the wings and outermost tail feathers) that sounds similar to a portion of the song, an intriguing observation discussed by Clark and Feo (2010).
The nest of an Anna's Hummingbird, which is relatively large for a hummingbird nest, is usually constructed on a branch of a tree or shrub, but may also be in vines, on wires, or under eaves. It is typically 1 to 8 m above the ground. Built by the female alone,it is a cup of plant fibers and spider webs. It is lined with fine plant down (and sometimes feathers) and the outside is camouflaged with lichens. The female may continue building after eggs are laid. The female incubates the 2 (rarely 1 or 3) white eggs by herself for 14 to 19 days. The young are fed by the female and take their first flight at around 18 to 23 days.
Anna's Hummingbird is very common over much of its range and has adapted well to suburban areas.
(Kaufman 1996; AOU 1998; Clark 2009; Clark and Feo 2010)
Male Anna's hummingbirds are easily recognized by their crimson crown (top of head) and gorget (throat). The tail is dark, the belly is greyish white, and the back is iridescent green as in most hummingbirds. Females and immatures lack the crimson crown and show varying degrees of red spotting on the throat. The tips of their tail feathers are white. Females and immatures of most hummingbird species are very difficult to tell apart, and field identification is often impossible.
This beautiful little bird occurs along the western edge of North America from southern Alaska to northwestern Mexico. Like other hummingbirds, Anna's is a skilled flyer that can hover in the air and fly backwards. It has a typical long, slender bill which it uses to feed on nectar, pollen, and insects. It often catches insects in flight, and it will stick out its long, skinny tounge during and after feeding.

Kalypta růžovohlavá (Calypte anna) je druh kolibříka, který obývá pacifické pobřeží Severní Ameriky od řeky Stikine po Kalifornský poloostrov, ve vnitrozemí zasahuje jeho rozšíření až do západního Texasu (od počátku dvacátého století se šíří severovýchodním směrem, osamělí jedinci byli zastiženi až na Newfoundlandu). Obývá křoviny chaparral, citroníkové háje i městské parky, počet kusů se odhaduje na půldruhého milionu. Objevitel kalypty René Primevère Lesson jí dal druhové jméno podle Anne d'Essling, dvorní dámy císařovny Evženie z Montijo a manželky vévody Françoise Victora Masseny, nadšeného ornitologa.
Dosahuje délky okolo 10 cm, rozpětí křídel 11–12 cm a hmotnosti 4–5 gramů. Má základní šedozelené zbarvení s černým ocasem, dospělí samci mají karmínovou hlavu a hrdlo. Zobák je dlouhý a tenký, díky daleko vytažitelnému jazyku se kalypta živí nektarem z květů a stromovou mízou, patří mezi významné opylovače.[2] Jídelníček si příležitostně zpestřuje hmyzem. Hlavními predátory jsou draví ptáci, kočky a hadi.
Kalypta růžovohlavá je jedním z mála druhů kolibříků, jehož samci při námluvách zpívají, kromě toho také vydávají silný zvuk způsobený vibrací ocasních per, když se vrhají z až třicetimetrové výšky.[3] Dosahuje největší relativní rychlosti letu ze všech obratlovců: 385 tělesných délek za sekundu.[4] Hnízdí podle geografické oblasti od prosince do června, snůška obsahuje obvykle dvě vejce, inkubace trvá 14 až 19 dní. Samice pečuje o mláďata sama, soběstačná jsou zhruba po třech týdnech.
V zimních měsících upadá kalypta růžovohlavá do stavu snížené fyzické aktivity (torpor).

Der Annakolibri (Calypte anna) gehört zur Familie der Kolibris (Trochilidae).
Der Annakolibri wird rund 10 Zentimeter lang und hat eine Flügelspannweite von 11,4 bis 12,1 Zentimetern. Die Kolibriart erreicht ein Gewicht von 4 bis 4,5 Gramm.[1] Die Geschlechter weisen in der Färbung des Gefieders einen deutlichen Dimorphismus auf. Das Gefieder schimmert bei den Männchen und Weibchen metallisch grün. Jungvögel und Weibchen erkennt man an der grauen Kehle und dem grünen Oberkopf. Die Kehle des Weibchens ist rot markiert. Beim Männchen sind Oberkopf und Kehle rot.
Der Annakolibri lebt im westlichen Nordamerika an der Pazifikküste in den Staaten British Columbia, Arizona und New-Mexico.[2] Er bevorzugt dichte Vegetation wie Hecken und Büsche. Die Vögel besiedeln aber auch Parks, Gärten und offene Wälder.
Die Nahrung des Annakolibris besteht hauptsächlich aus Blütennektar und Pollen. Der Nektar wird im Flug aus den Blüten aufgenommen. Zudem werden Insekten von den Kolibris gefressen, was eine ausreichende Versorgung mit Eiweiß sicherstellt.
Bei der Balz machen die Männchen Sturzflüge aus bis zu dreißig Metern Höhe.[3] Dabei erzeugt das Männchen eine Reihe von Geräuschen, deren lautestes und markantestes an der tiefsten Stelle des Fluges erklingt, bevor es wieder an Höhe gewinnt. Der Ursprung dieses Klangs war unter Biologen lange Zeit umstritten. Forscher haben herausgefunden, dass die Innenseiten der äußersten Schwanzfedern zu vibrieren beginnen, wenn das Männchen beim Sturzflug die Geschwindigkeit von 23 Metern pro Sekunde überschreitet.[4] Die Schwanzfedern schwingen dabei ähnlich wie das Rohrblatt im Mundstück einer Klarinette. Der Ton klingt dann wie ein Zirpen.
Das Männchen begattet häufig mehrere Weibchen, trennt sich danach aber jeweils sofort von ihnen. Nach der Begattung wird in niedriger Höhe ein kleines Nest aus Spinnweben, Pflanzenwolle, Flechten oder Moos gebaut. Das Nest wird versteckt in einem Strauch oder einem Baum angelegt. Das Weibchen legt im Durchschnitt zwei Eier, die Jungvögel schlüpfen nach einer Brutzeit von 14 bis 19 Tagen. Die Küken sind beim Schlupf blind und ungefiedert. Nach 18 bis 23 Tagen sind die Jungen flügge.
Neben dem Menschen, der den Lebensraum des Kolibris zerstört und Teile dieses Vogels zu Schmuck verarbeitet, haben die Kolibris auch natürliche Feinde wie Schlangen, Katzen und Greifvögel.
Der Gesamtbestand dieser Art wird derzeit nicht als bedroht angesehen. In der Roten Liste der Weltnaturschutzunion wird der Annakolibri daher in der Kategorie „LC“ (least concern – nicht gefährdet) geführt.
Bezogen auf ihre Körpergröße sind Annakolibris die wohl schnellsten Wirbeltiere der Welt.[5] So erreichen die Tiere bei ihren Balzflügen (s. o.) Geschwindigkeiten von 385 Körperlängen pro Sekunde (entspricht 27,3 m/s oder 98,28 km/h), bei Beschleunigungswerten von etwa dem Zehnfachen der Erdbeschleunigung. Zum Vergleich: Wanderfalken kommen im Sturzflug auf Geschwindigkeiten von bis zu 200 Körperlängen pro Sekunde, Kampfjets, wie zum Beispiel die MiG-25 (ein Mach 3 schneller Abfangjäger), erreichen dagegen maximal nur das rund 40-fache ihrer Gesamtlänge.
Im Moment sind keine Unterarten des Annakolibris bekannt. Er gilt als monotypisch.[6]
René Primevère Lesson beschrieb den Annakolibri unter dem Namen Ornismya Anna. Als Fundort nannte er Kalifornien. Das Typusexemplar wurde von Paul-Émile Botta gesammelt und kam 1829 ins Naturalienkabinett von François Victor Masséna, dem zweiten Herzog von Rivoli und dritten Fürsten von Essling (1799–1863).[7] Später wurde die Art der 1856 von John Gould neu eingeführten Gattung Calypte zugeordnet.[8] Der Ursprung des Namens »Calypte« ist nicht ganz eindeutig. Eventuell ist das Wort vom griechischen »kalyptrē, kalyptō καλυπτρη, καλυπτω« für »Schleier, bedecken« abgeleitet.[9] Laut Elliott Coues (1842–1899) könnte Calypte ein Name sein, der durch Kalypso aus der griechischen Mythologie hervorging.[10] Das Artepitheton »anna« widmete Lesson Anna Debelle Masséna, Prinzessin von Essling und Herzogin von Rivoli (1802–1887).[11]

Anna's hummingbird (Calypte anna) is a medium-sized bird species of the family Trochilidae. It was named after Anna Masséna, Duchess of Rivoli.
It is native to western coastal regions of North America. In the early 20th century, Anna's hummingbirds bred only in northern Baja California and Southern California. The transplanting of exotic ornamental plants in residential areas throughout the Pacific coast and inland deserts provided expanded nectar and nesting sites, allowing the species to expand its breeding range. Year-round residence of Anna's hummingbirds in the Pacific Northwest is an example of ecological release dependent on acclimation to colder winter temperatures, introduced plants, and human provision of nectar feeders during winter.
These birds feed on nectar from flowers using a long extendable tongue. They also consume small insects and other arthropods caught in flight or gleaned from vegetation.
Anna's hummingbird was formally described and illustrated in 1829 by the French naturalist René Lesson in his Histoire naturelle des Oiseaux-Mouches from a specimen that had been collected in California. Lesson placed it in the genus Ornismya and coined the binomial name Ornismya anna.[2][3] Anna's hummingbird is now placed in the genus Calypte that was introduced in 1856 by the English ornithologist John Gould.[4][5] Gould did not explain the derivation of the genus name but it is probably from the Ancient Greek kaluptrē meaning "woman’s veil" or "head-dress" (from kaluptō meaning "to cover"). The specific epithet anna was chosen to honour Anne d'Essling who married the ornithologist François Victor Massena, 3rd Duke of Rivoli.[6] The species is monotypic: no subspecies are recognised.[5]
Anna's hummingbirds are 3.9 to 4.3 in (9.9 to 10.9 cm) long with a wingspan of 4.7 inches (12 cm) and a weight range of 0.1 to 0.2 oz (2.8 to 5.7 g).[7] They have an iridescent bronze-green back, a pale grey chest and belly, and green flanks. Their bills are long, straight, and slender. The adult male has an iridescent crimson-red, derived from magenta, to a reddish-pink crown and gorget, which can look dull brown or gray without direct sunlight, and a dark, slightly forked tail. Females also have iridescent red gorgets, although they are usually smaller and less brilliant than the male.[7]
The male Anna's hummingbird is the only North American hummingbird species with a red crown.[7][8] Females and juvenile males have a dull green crown, a grey throat with or without some red iridescence, a grey chest and belly, and a dark, rounded tail with white tips on the outer feathers.[8]
The male has a striking reddish-pink crown and gorget, which are strongly iridescent and dependent on the angle of illumination and observation by female or male competitor birds.[8] The iridescence results from large stacks of melanosomes in the feather barbules, occurring as layers separated by keratin.[8] The barbules reflect incident light in the manner of partially-opened Venetian blinds, enabling the iridescence – which varies the head and gorget coloration with the changing angle of light – as a coloration advantage for courtship attraction and territory defense.[8]
Male birds with elevated levels of protein in their diet have more colorful crowns and higher iridescence in their head feathers compared with male birds with low protein intake.[9]
The male's call – scratchy and metallic – is typically used as the bird perches in trees and shrubs.[7] Anna's hummingbirds have adapted to urban environments and are commonly seen in backyards and parks, and at feeders and flowering plants. Anna's hummingbirds eat flying insects.[10]
According to a 2021 estimate, there are 8 million Anna's hummingbirds in the western United States and Canada,[11] with the population increasing since 1970.[12] As of 2021, the International Union for Conservation of Nature Red List of Threatened Species lists the Anna's hummingbird among species of least concern.[1]
Anna's hummingbirds are found along the western coast of North America, from southern Canada to northern Baja California, and inland to southern and central Arizona, extreme southern Nevada and southeastern Utah, and western Texas.[7][13] They tend to be permanent residents within their range. However, birds have been spotted far outside their range in such places as southern Alaska, Saskatchewan, New York, Florida, Louisiana, and Newfoundland.[14][15]
In response to rising temperatures at low elevations during climate change in the 21st century, Anna's hummingbirds have expanded their range into the cooler summer environments of higher-altitude (up to 2,825 metres (9,268 ft)) mountainous terrains of California, such as the Sierra Nevada.[16]
Anna's hummingbirds have the northernmost year-round range of any hummingbird. Birds have been recorded in Alaska as early as 1971, and resident in the Pacific Northwest since the 1960s, particularly increasing as a resident population during the early 21st century.[17][18] Scientists estimate that some birds overwinter and presumably breed at northern latitudes where food and shelter are available throughout winter, tolerating moderately cold winter temperatures.[17][18]
During cold temperatures, Anna's hummingbirds gradually gain weight during the day as they convert sugar to fat.[19][20]
While their range was originally limited to the chaparral of California and Baja California, it expanded northward to Oregon, Washington, and British Columbia, and east to Arizona in the 1960s and 70s.[17] This rapid expansion is attributed to the widespread planting of non-native species, such as eucalyptus, as well as the use of urban bird feeders, in combination with the species' natural tendency for extensive postbreeding dispersal.[7]
In the Pacific Northwest, the fastest growing populations occur in regions with breeding-season cold temperatures similar to those of its native range.[17] Northward expansion of the Anna's hummingbird represents an ecological release associated with introduced plants, year-round nectar availability from feeders supplied by humans, milder winter temperatures possibly associated with climate change, and acclimation of the species to a winter climate cooler than its native region.[17][18] Although quantitative data are absent, it is likely that a sizable percentage of Anna's hummingbirds in the Pacific Northwest still do migrate south for winter, as of 2017.[18]
Anna's hummingbirds with inadequate stores of body fat or insufficient plumage are able to survive periods of subfreezing weather by lowering their metabolic rate and entering a state of torpor.[16][21]
When studied in colder temperatures at mountainous elevations, Anna's hummingbirds used torpor more frequently than at lower elevations.[16]
While collecting nectar, the Anna's hummingbird assists in plant pollination.[12] There is evidence that Anna's hummingbirds in flight generate an electrostatic charge that adheres pollen to their beaks and feathers, facilitating transfer of pollen grains to hundreds of flowers per day while foraging for nectar.[22] This species sometimes consumes tree sap.[23]
Anna's hummingbirds can shake their bodies 55 times per second to shed rain while in flight, or in dry weather, to remove pollen or dirt from feathers.[24] Each twist lasts four-hundredths of a second and applies 34 times the force of gravity on the bird's head.[24]
During hovering flight, Anna's hummingbirds maintain high wingbeat frequencies accomplished by their large pectoral muscles via recruitment of motor units.[25] The pectoral muscles that power hummingbird flight are composed exclusively of fast glycolytic fibers that respond rapidly and are fatigue-resistant.[25]
Unlike most northern temperate hummingbirds, the male Anna's hummingbird sings during courtship. The song is thin and squeaky, interspersed with buzzes and chirps, and is drawn to over 10 seconds in duration. During the breeding season, males can be observed performing an aerial display dive over their territories. When a female flies onto a male's territory, the male rises up about 130 ft (40 m) before diving over the female. As the male approaches the bottom of the dive, it reaches an average speed of 27 m/s (89 ft/s), which is 385 body lengths per second.[26] At the bottom of the dive, the male travels 23 m/s (51 mph), and produces an audible sound produced by the tail feathers, described by some as an "explosive squeak".[27][28]
Open-wooded or shrubby areas and mountain meadows along the Pacific coast from British Columbia to Arizona make up C. anna's breeding habitat. The female raises the young without the assistance of the male. The female bird builds a nest in a shrub or tree, in vines, or attached to wires or other artificial substrates. The round, 3.8-to-5.1-centimetre (1.5 to 2.0 in) diameter nest is constructed of plant fibers, downy feathers and animal hair; the exterior is camouflaged with chips of lichen, plant debris, and occasionally urban detritus such as paint chips and cigarette paper.[13] The nest materials are bound together with spider silk. They are known to nest as early as mid-December and as late as June, depending on geographic location and climatic conditions.[7][29]
Anna's hummingbirds may hybridize with other species, especially the congeneric Costa's hummingbird.[13] These natural hybrids have been mistaken for new species. A bird, allegedly collected in Bolaños, Mexico, was described and named Selasphorus floresii (Gould, 1861), or Floresi's hummingbird. Several more specimens were collected in California over a long period, and the species was considered extremely rare.[30]
The specimens were the hybrid offspring of an Anna's hummingbird and an Allen's hummingbird. A single bird collected in Santa Barbara, California, was described and named Trochilus violajugulum (Jeffries, 1888), or violet-throated hummingbird.[31] It was later determined to be a hybrid between an Anna's hummingbird and a black-chinned hummingbird.[32][33]
In the 2017 Vancouver Official City Bird Election, Anna's hummingbird was named the official bird of the city of Vancouver, British Columbia.[34] Anna's hummingbirds are non-migrating residents of Seattle where they live year-round through winter, enduring extended periods of subfreezing temperatures, snow, and high winds.[35]

Anna's hummingbird (Calypte anna) is a medium-sized bird species of the family Trochilidae. It was named after Anna Masséna, Duchess of Rivoli.
It is native to western coastal regions of North America. In the early 20th century, Anna's hummingbirds bred only in northern Baja California and Southern California. The transplanting of exotic ornamental plants in residential areas throughout the Pacific coast and inland deserts provided expanded nectar and nesting sites, allowing the species to expand its breeding range. Year-round residence of Anna's hummingbirds in the Pacific Northwest is an example of ecological release dependent on acclimation to colder winter temperatures, introduced plants, and human provision of nectar feeders during winter.
These birds feed on nectar from flowers using a long extendable tongue. They also consume small insects and other arthropods caught in flight or gleaned from vegetation.

Calypte anna
Le Colibri d'Anna (Calypte anna) est une espèce d'oiseau appartenant à la famille des Trochilidae.
Le nom de l'espèce a été donné par René Primevère Lesson en l'honneur de la femme du deuxième duc de Rivoli (grand collectionneur d'oiseaux)[1], Anna de Belle Masséna[2] (1802-1887).
Cet oiseau mesure 10 à 11 centimètres de longueur. Il a un dos vert-bronze, une poitrine gris pâle et le ventre et les flancs verts. Son bec est long, droit et fin. Le mâle adulte a une couronne et une gorge d'un rouge irisé rouge cramoisi avec une queue noire légèrement fourchue. C'est la seule espèce de colibri d'Amérique du Nord avec une couronne rouge. Les femelles et les juvéniles ont une couronne verte, une gorge grise avec quelques taches rouges, une poitrine et un ventre gris, et une queue noire arrondie avec du blanc sur l'extrémité des rectrices externes. Le plumage sur son cou et sa tête change de couleur en fonction de l'orientation, c'est un phénomène d'Iridescence.
Ces oiseaux se nourrissent du nectar des fleurs en utilisant leur longue langue extensible. Ils consomment également de petits insectes qu'ils attrapent en vol. Ils visent l'insecte en ouvrant largement leur bec. Cette technique a un meilleur taux de succès que d'essayer de viser l'insecte avec leur long bec fin.
En collectant du nectar, ils aident aussi à la pollinisation des plantes. Cette espèce consomme parfois la sève des arbres.
Cet oiseau se trouve au Canada, aux États-Unis et au Mexique.

Multimedia w Wikimedia Commons Koliberek żarogłowy (Calypte anna) – gatunek małego ptaka z rodziny kolibrowatych (Trochilidae). Zamieszkuje zachodnią Amerykę Północną. Nie jest zagrożony wyginięciem.
Po raz pierwszy gatunek opisał René Lesson w 1829 w swojej książce Histoire naturelle des oiseaux-mouches[4]. Nowemu gatunkowi nadał nazwę Ornismya Anna[4]. Holotyp pochodził z San Francisco (Kalifornia)[4]. Obecnie (2017) Międzynarodowy Komitet Ornitologiczny umieszcza koliberka żarogłowego w rodzaju Calypte jako jeden z dwóch gatunków. Uznaje gatunek za monotypowy[5].
Epitet gatunkowy jest eponimem honorującym księżniczkę d’Essling i księżną de Rivoli Annę d’Essling (1802–1887), szefową dwórek cesarzowej Eugenii oraz żonę francuskiego kolekcjonera Françoisa Masséna III księcia d’Essling i II diuka de Rivoli[6].
Długość ciała wynosi 10–11 cm; masa ciała samca 3,3–5,8 g, samicy 3,3–4,7 g[2]. Charakterystyczne, różowoczerwone gardło i ciemię. U samicy występują na gardle delikatne, czerwone plamki; wierzch ciała zielony, spód szary; ogon z białymi rogami[7].
Koliberki żarogłowe zamieszkują południowo-zachodnią Kanadę (Kolumbia Brytyjska) na południe przez zachodnie Stany Zjednoczone (na wschód po południową Arizonę) po północno-zachodni Meksyk (północno-zachodnia Kalifornia Dolna). Miejsce zimowania zmienne. Kolibry te pojawiają się nieregularnie na południe po północny stan Sonorę, na południowy wschód po wybrzeże Zatoki Meksykańskiej, na północ po południowo-wschodnią Alaskę. Sporadycznie wędrują dalej na wschód[2].
Środowiskiem życia koliberków żarogłowych są ogrody, kaniony, podnóża gór, nadrzeczne zadrzewienia[7], chaparral[2]. Koliberki żarogłowe żywią się nektarem, żywicą drzew oraz niewielkimi owadami i pajęczakami. Odwiedzają również karmniki ze słodką wodą dla kolibrów[8].
Długi, nurkowy lot tokowy zakończony gwałtownym, głośnym trzepotaniem skrzydeł przed samicą[7]. Okres lęgowy trwa od listopada do maja, czasami do czerwca[2]. Za budowę gniazda, wysiadywanie i odchów młodych odpowiada samica[8]. Umieszczone jest na drzewie lub krzewie. Budulec stanowią głównie włókna roślinne, puch i sierść. Zewnętrzna warstwa zamaskowana jest martwą materią roślinną, mchem i porostami. Średnica gniazda wynosi 3,8–5,1 cm[9]. Zniesienie wynosi 2 jaja, skorupki są owalne, białe. Inkubacja trwa 14–19 dni. Pisklęta otwierają oczy po 5 dniach życia. Samica opiekuje się młodymi w gnieździe przez kolejne 18–23 dni[8].
IUCN uznaje koliberka żarogłowego za gatunek najmniejszej troski (LC, Least Concern) nieprzerwanie od 1988 (stan w 2017)[10].

O nome da ave lembra Anna Masséna, duquesa de Rivoli[1]. É a única espécie de colibri que inverna nas regiões temperadas frias, onde se sustenta das flores remanescentes e das suas reservas de gordura, sendo muito eficaz na conversão de açúcares em gordura[2]. Quando as reservas energéticas são insuficientes, ou quando a plumagem não forneça isolamento adequado, sobrevive a períodos frios, incluindo temperaturas abaixo do ponto de congelação da água, escondendo-se em cavidades e reduzindo o ritmo metabólico, entrando então num estado de torpor[3].

Annas kolibri[2] (Calypte anna) är en fågelart i familjen kolibrier från västra Nordamerika.[3] Den beskrevs vetenskapligt år 1829 av René Primevère Lesson, som gav den namn efter Anna Masséna, hertiginna av Rivoli.
Annas kolibri har en längd på omkring tio centimeter och vikten är tre till sex gram. Den har en bronsgrönaktig färg på ovansidan av kroppen, grönaktiga sidor och blekt gråaktigt bröst och undersida. Näbben är lång, rak och smal.
Den adulta hanen har glänsande karmosinröd hätta och strupe samt mörka stjärtfjädrar. Honor och juvenila fåglar är grönaktig på huvudet och har gråaktig strupe med bara något mindre inslag av rödaktiga fjädrar, gråaktigt bröst och undersida och mörk stjärt med lite vitt i spetsen på de yttersta fjädrarna.
Annas kolibri förekommer i trakterna längs Nordamerikas Stillahavskust, från sydligaste Kanada till norra Baja California. Den klarar vintern på dessa för en kolibri mycket nordliga breddgrader tack vare tillgången på vinterblommande växter och genom omvandling av sockret i nektaren till fett. Vid kallare temperaturer kan den också falla i ett dvalliknande tillstånd för att spara energi.
Dess föda är främst nektar, men den kan också fånga små insekter i flykten. Ibland äter den även sav. Hanen är revirhävdande och uppvisar en spektakulär parningsflykt, som inkluderar att först flyga upp och sedan dyka ner mot honan från hög höjd. Även sång ingår i uppvaktningen. Uppfödningen av ungarna sköts av honan ensam.
Arten har ett stort utbredningsområde och en stor population, och tros öka i antal.[1] Utifrån dessa kriterier kategoriserar internationella naturvårdsunionen IUCN arten som livskraftig (LC).[1]

Калипта Анны[1] (лат. Calypte anna) — птица семейства колибри. Вид получил название в честь Анны Массена, герцогини де Риволи (1802—1887)[2].
Калипта Анны длиной примерно 10 см, размах крыльев составляет от 11,4 до 12,1 см, вес от 4 до 4,5 г. Присутствует отчётливый половой диморфизм. Оперение у самцов и самок переливающееся зелёное с металлическим отливом. У молодых птиц и самок горло серое, а верхушка головы зелёная. Горло самки с отдельными красными отметинами. У самца верхушка головы и горло красные.
Калипта Анны живёт на западе Северной Америки на тихоокеанском побережье в провинции Британская Колумбия (Канада), от штата Орегон и до штатов Аризона и Нью-Мексико (США)[3]. Птицы предпочитают густую растительность, такую как живые изгороди и кусты, однако могут селиться также в парках, садах и открытом лесу.
Питание калипты Анны состоит преимущественно из нектара цветов и пыльцы, которые она собирает из цветков, зависая в воздухе. Кроме того, колибри питаются насекомыми, обеспечивая себя достаточным количеством белка.
В брачный период самец взлетает в высоту до 30 м и летит по вогнутой дуге вниз в направлении самки.[4]. В нижней части дуги самец издает высокий (порядка 4 кГц) и очень громкий звук, напоминающий короткий (примерно 1/20 секунды) пронзительный свист. О природе этого звука долгое время шли споры среди биологов. Исследователи установили, что громкий звук раздаётся как раз в те доли секунды, когда самец колибри распускает хвост. Внутренние стороны наружных рулевых перьев хвоста начинают вибрировать, когда при пикировании скорость полёта самца составляет более 23 м в секунду. При этом перья хвоста вибрируют так же, как трость в мундштуке кларнета[5].
Самец часто оплодотворяет несколько самок и сразу после этого расстаётся с ними. После совокупления самка строит маленькое гнездо из паутины, пуха растений, лишайников или мха. Гнездо устраивается на небольшой высоте незаметно в кусте или на дереве. Самка откладывает в среднем 2 яйца, выводок появляется на свет через 14—19 дней. Птенцы рождаются слепые и неоперённые. Через 18—23 дня они становятся самостоятельными.
Наряду с человеком, который разрушает жизненное пространство колибри и использует перья этой птицы для украшений, естественными врагами птицы являются змеи, кошки и дневные хищные птицы.
Относительно длины своего тела калипта Анны является, пожалуй, самым быстрым позвоночным животным мира[6]. Так, во время брачных полётов птицы достигают скорости 385 размеров тела в секунду (27,3 м/с или 98,28 км/ч), испытывая перегрузки, равные примерно 10 g (ускорений свободного падения у поверхности земли). Для сравнения, сапсаны во время пикирующего полёта развивают скорость до 200 размеров тела в секунду, самолёты-истребители, как, например, МиГ-25, могут достигать только 40-кратного отношения[7].
В 2014 году было выполнено секвенирование полной геномной последовательности представителя семейства колибри — калипты Анны (C. anna)[8]. Благодаря достаточно хорошему качеству сборки генома C. anna, вид имеет важное значение в сравнительной геномике для выяснения эволюции птичьих геномов[9][10].
