Die Tüpfelpfeifgans (Dendrocygna guttata), auch Tüpfelbaumente genannt, ist eine mittelgroße Art aus der Unterfamilie der Pfeifgänse. Namensgebend ist die auffallende Tüpfelung auf den Seiten des Rumpfes. Sie kommt auf Mindanao, auf Sulawesi, den Molukken, den Tanimbarinseln, im Tiefland Neuguineas und auf dem Bismarck-Archipel vor. Auf Neuguinea zählt diese Art zu den häufigsten Enten.
Ausgewachsen erreichen Tüpfelpfeifgänse eine Länge von 42 bis 50 Zentimetern und ein Gewicht von etwa 800 g. Ihr Gefieder ist bräunlich, der Kopf grau. Der Bauch ist mit großen, runden Flecken gezeichnet. Bei Jungvögeln ist die Zeichnung mehr verwischt, mit weißen, dunkel umrandeten Federn an den Flanken. Wie die übrigen Arten der Pfeifgänse haben sie lange Beine und große Füße mit Schwimmhäuten. Ein ausgeprägter Geschlechtsdimorphismus besteht nicht.
Ihr bevorzugter Lebensraum sind ganzjährig flache Süßgewässer in den Tiefebenen und Küstenregionen. Sie bevorzugen dabei Regionen, die von Bäumen umstanden sind. Ihre Ruheplätze sind über die Wasserfläche hinausragende Äste sowie die unbelaubten Kronen von Bäumen. Die Brutzeit beginnt in Neuguinea nach dem Einsetzen der Regenzeit in August und September, erstreckt sich aber über viele Monate. Das jeweilige Gelege wird zwischen 28 und 30 Tagen bebrütet. Bei in Gefangenschaft gehaltenen Tüpfelpfeifgänsen umfasst ein Gelege zwischen sechs bis 12 Eier. Die Jungvögel werden in der siebten Woche nach dem Schlüpfen flügge und sind ab dem 2. Lebensjahr geschlechtsreif.
Die Tüpfelpfeifgans ernährt sich überwiegend von den grünen Teilen von Wasserpflanzen sowie den Samen von Riedgräsern.

The spotted whistling duck (Dendrocygna guttata) is a member of the duck family Anatidae. It is also referred to as the "spotted tree duck".[2] This duck resides in Indonesia, New Guinea, Australia and the Philippines, but captive populations can be found elsewhere in the world.
The Spotted whistling duck is one of the smaller species in the genus Dendrocygna.[3] This duck grows to 43-50 cm tall. Males can weigh anywhere from 590g to 650g while females weigh 610g to 860g. White spots on their flanks and breasts gave these ducks the spotted name. The sides of the neck, faces, and eyebrows are all grey. Black or dark brown coloring stretches from the crown nape to the hindneck. This dark coloring is also found in the eyepatch. Their coloring resembles a cape with a thick collar. This cape starts as a light brown then fades into a darker brown closer to the tail. Their underbelly is mostly brown, sometimes spotted, and significantly lighter than the wings and the “collar.” A white bar on the upper tail coverts can be seen during flight aiding in identification. They have dull pink legs[4] with black webbed feet and sharp nails.[5] The bill is dark, yet often seen with portions of red and a small white mark on the lower mandible.[6] Spotted whistling ducks look as though they are raised from the ground, as though they are standing up tall.[5] (look more into this). Their wings pressed strongly against the body.[5] Inner vanes of the outer primaries are jagged and can be seen in flight (check on this).[5] While flying, the head is positioned down causing the whole bird to look hunched. The tail stays pointed and looks long when in flight.[5]Juveniles are seen with white streaks on flanks instead of spots[4] and have significantly duller coloring.[6] Spotted whistling ducks are visually similar to D. arborea, yet many scientists believe its closest relative is D. eytoni.[6] After gaining their adult plumage at the age of 6 months,[7]. the spotted whistling duck has a single annual molt.[3] Like other ducks, swans, and geese, the spotted whistling duck molts synchronously. Synchronous molting is common within Anseriformes because waterfowl have the ability to avoid terrestrial predators. Unlike other birds, waterfowl float in ponds lakes while they molt, safe from predators. Other more evolved ducks have two molts, whistling ducks only molt once.[8]
The spotted whistling duck, Dendrocygna guttata, was first reported in 1866.[9] Like all other birds, it is an animal in the phylum Chordata and the class Aves. The spotted whistling duck is a part of the order Anseriformes, which includes all waterfowl. Swans, geese, and ducks are all a part of the family Anatidae. Within Anatidae, the family Dendrocygna encompasses all whistling ducks.[9] Bird phylogenies are difficult to determine due to massive adaptive radiations throughout history. Scientists change phylogenetic trees often as new genetic information becomes available. In Australia philogonies are especially difficult, due to visually similar endemic and monotypic genera. Before genetic information was available, the Dendrocygna was classified within Anserinae by Delacour and Mayr. Within Anserinae, the Dendrocygna and Thalassornis were combined into one by Monrow in 1990 using DNA-DNA hybridization data. This genus then stayed consistent. Using mitochondrial DNA in 1996 Swaml et al. discovered Dendrocyna diverged first following Anseranatidae. This genus is the most basal group after the magpie goose. Whistling ducks are more closely related to swans and geese than the “true ducks” such as mallards.[8] Then, in 2002 a study using sequenced DNA from the complete mitochondrial control region supported the 1996 conclusion. Within Denrocygna, the Spotted Whistling Duck was the most recent species discovery. In 1995 Livezey partitioned clades within the Dendrocygna, one clade including the Fulvous Whistling-Duck, Lesser whistling, D. arcuata and D. eytoni. D. arcuata and D. javanica are sister species. Outside this clade, the spotted whistling duck and the West Indian whistling duck are sister species.[8]
Whistling ducks are found all over the world. The spotted whistling duck is distributed throughout the Philippines, Australia, and New Guinea.[6] These ducks live in the southern part of the Philippines and several islands of Indonesia. In Indonesia spotted whistling ducks stretch from the Eastern Lesser Sundas islands to new guinea. Spotted whistling ducks are also found in Weipa and Iron ranges of Australia, but have also been seen at Wonga Beach. Scientists hypothesize the Indonesian population was introduced due to a storm blowing the birds off course.[4]
Spotted whistling ducks live around bodies of water, like many other ducks. These ducks specifically live around small ponds and marshes surrounded by trees. They prefer humid and low altitude habitats.[4] Spotted whistling ducks build hollows within the trees surrounding their habitats.[8]
The Diet of the spotted whistling duck contains grass seeds, aquatic invertebrates, aquatic plants, and small fish.[6] These ducks obtain their food by dabbling and diving. The ducks dabble at the surface of the ponds, filtering the water through their bills. The birds bounce on the surface to enter the water headfirst, after being underwater for a maximum of 15 seconds they emerge with another bounce. Scientists never observed food in the bill after the diving behavior. They concluded the birds consume the food while underwater.[10] (Beruldsen) The majority of feeding occurs at night.[11]
The genus Dendrocygna has strong pair bonds. Male and female birds are visually similar, females are slightly heavier than males. Without weighing the bird sex is difficult to determine. Breeding season begins in September with active nests found as late as April. Their nests are found in hollowed-out trees. Both parents participate in nest building at the same time. One pair can have several clutches a year consisting of 10-11 eggs. Both parents incubate the eggs [12] for 18-31 days and when hatched the chick weighs 17.5g.[6] In captivity, the chicks fledged at 7 weeks,[6] yet in the wild scientists have observed chicks flying at 45-50 days old.[5] The spotted whistling duck has a breeding system described as ‘primitive,’ which is consistent with other basal groups in Anseriformes.[3]
Spotted whistling ducks are found in groups with their own species and often with D. arcata.[6] Compared to others in the genus, these ducks are less vocal.[5] These birds perch on tree branches in groups slightly smaller than flocks. The flocks are often a mix of adults and juveniles. The adults shepard the juveniles keeping them close to the group. In 2000 Beruldsen observed a group consisting of 6 juveniles and two adults, male and female. The juveniles seemed unbothered by the human presence, but the adults made sure there was distance between Buruldsen and the juveniles. The birds kept their distance but seemed to be unaffected. The adult male positioned himself between the juveniles and the humans, protecting the other birds. This behavior was often accompanied by several high-pitched ticking calls.[10]
The spotted whistling duck is listed as least concern.[1] Their population is stable with populations ranging from 10,000 to 25,000 birds. [6] In captivity they were found to be specifically susceptible to avian tuberculous. Twenty-seven percent of bird species get avian tuberculosis and the disease is usually fatal. Spotted whistling ducks die at a higher rate than other birds. Within one collection of captive birds, the death rate of avian tuberculous reached 70% with the majority of deaths occurring from January to March. The relatively small size of this bird could explain the increased death rate.[3]
The spotted whistling duck is not hunted often. These ducks are found in captivity, like many other duck species.[12]

Dendrocygna guttata
Le Dendrocygne tacheté (Dendrocygna guttata) est une espèce d'oiseau appartenant à la famille des anatidés. C'est l'espèce la moins connue du groupe des dendrocygnes.
Cet oiseau mesure entre 43 et 50 cm. La tête est grise avec une calotte noire et le tour des yeux noirâtre, le bec est rougeâtre. Le dessous du corps est tacheté de blanchâtre, le reste du plumage est brun foncé. Les pattes sont nuancées de rose.
Le plumage des jeunes est plus terne avec les côtés de la poitrine plus rayés que tachetés.
On rencontre cette espèce en Indonésie, aux Philippines (Mindanao) et en Nouvelle-Guinée. Elle fréquente les lacs et les marais généralement boisés.
C'est un des dendrocygnes qui se perche le plus souvent dans les arbres. Il vit en couples ou en petits groupes se nourrissant surtout le jour. La reproduction peut avoir lieu toute l'année, le nid est situé dans un arbre creux.
Cette espèce est souvent associée au Dendrocygne à lunules.
Bien que mal connu, le Dendrocygne tacheté ne semble pas menacé, on estime entre 10 000 et 25 000 le nombre d'individus.

Perleplystreand (Dendrocygna guttata) er en monotypisk art i gruppen av plystreender (Dendrocygninae) som inngår i slekten Dendrocygna (treender). Arten er utbredt i den australasiatiske sona, fra de sørlige Filippinene (Mindanao og Sulawesi) og østover gjennom Molukkene og de østre små Sundaøyene, til Ny-Guinea, Bismarckarkipelet og, nylig, Cape York-halvøya i det nordøstre Australia.[2][3]
Perleplystreand måler cirka 43–50 cm, og hunnen blir større enn hannen. Hannen veier typisk 590–650 g, hunnen typisk 610–860 g. Kjønnene er ellers tilnærmet like, men ungfuglene er gjerne noe dusere utfarget og har hvite flankefjær med sort kanttrim.[2]
Fjærdrakten er hovedsakelig rødbrun og mørkere brun. Ansiktet og øverste del av halsen er grått, og arten har mørk maske og ei mørkere smal stripe som renner gjennom øyene. issen er mørk og det mørke fortsetter som ei bred rand nedover nakken til ryggen. Videre nedover halsen og brystet og ryggen er den rødbrun med små lysere flekker. I buken går flekkene over til gradvis større og runde hvite markeringer. Vingefjærene på oversiden av vingen mørk brune med lys kanttrim. Nebbet er sort og læraktig.[2]
Vokaliseringen består er et enkelt nasalt «gakk», et plystrende «viii» eller et hest «vi-a-viii-viii», «vu-viouv-vi» eller «vu-viouvi». Den kan også uttrykke et nasalt «zziou» og et pipende «ti-ti-ti».[2]
Arten trives i våtmarksområder med myr, sump, mangrove, innsjøer, bekker og elver omgitt av gressland og spredte trær. Den er nattaktiv og opptrer kun i lavlandet, der den ernærer seg av gressfrø og snegler. Arten er sosial og opptrer ofte i blandet flokk med hetteplystreand (D. arcuata). Den er sannsynligvis standfugl, men det er uklart om populasjonene på enkelte øyer kan migrere.[2]
Hekketiden følger regntiden og varierer noe med utbredelsen. Redet bygges i hule trær, som regel nær vann. Hunnen legger normalt 10–11 egg. Inkubasjonstiden varer i cirka 28–31 dager. I fangenskap får avkommet full fjærdrakt etter cirka sju uker.[2]
Inndelingen følger HBW Alive og er i henhold til Carboneras (2018).[4] Norske navn på arter følger Norsk navnekomité for fugl og er i henhold til Syvertsen et al. (2008, 2017).[5][6] Eventuelle benevnelser i parentes er kun midlertidige beskrivelser, i påvente av et offisielt navn på arten.

Пятнистая свистящая утка[1], или пятнистая древесная утка[2] (лат. Dendrocygna guttata) — вид свистящей или древесной утки.
В длину достигает 42—50 см при весе около 800 г. Оперение коричневое с белыми пятнами на брюхе, голова серая. Лапы относительно длинные с синеватыми перепонками. Существенного полового диморфизма не наблюдается.
Пятнистая свистящая утка обитает на островах Австралазии: на Новой Гвинее, Сулавеси, Минданао, Малых Зондских островах, архипелаге Бисмарка. Они селятся у небольших пресных водоёмов или на побережии островов, рядом с которыми имеются пущи деревьев.
Точных данных о численности птиц не имеется. По некоторым источникам, в 1999 году их насчитывалось не менее 25 000 особей.[3]
Брачный период начинается после начала сезона дождей в августе-сентябре. Самка обычно откладывает от 6 до 12 яиц, которые содержатся в гнезде в течение месяца. После вылупления птенцы начинают летать на седьмой неделе, а половой зрелости достигают к двум годам.
