Lavia frons rotates its head almost 180 degrees to observe predators. They are always on the watch and therefore, are not frequently preyed upon. There have been, however, reports of Lavia frons being captured by predators (Vaughan and Vaughan, 1986).

Known Predators:

  • mambas (Dendroaspis angusticeps)
  • bat hawks (Machaerhamphus anderssoni)
  • night tree vipers (Boiga blandingii)
  • European kestrels (Falco tinnunculus)

Morphology ( Inglês )

fornecido por Animal Diversity Web

Lavia frons is an average-sized bat with the female slightly larger than the male. The weight of Lavia frons (male and female considered) ranges from 28 to 36 grams (Kingdon, 1974). The length from head to tail of females ranges from 63 to 80 mm while the length of males goes from 58 to 80 mm (Rosevear, 1965).

An important defining characteristics of bats is their forearm length. Females have forearm lengths of 55 to 63 mm; males, from 55 to 60 mm. Ear length of females ranges from 36 to 47 millimeters and for males, from 35 to 45 mm. The tibia length ranges from 33 to 37 mm for females and from 32 to 36 mm for males. The length of the skull ranges from 23.3 mm to 26.1 mm for females and 22.8 to 25.0 mm for males (Rosevear, 1965). Members of this species have prominent postorbital processes.

The dental formula is 0/2 1/1 1/2 3/3 (upper/lower incisors, upper/lower canines, upper/lower premolars, upper/lower molars). Lavia frons, like other Megadermitidae, has no upper incisors. The molars are dilambdodont, which is consistent with eating insects. There is a cingulum on the canine as well as two secondary cusps. The premolars are quite large with the posterior premolars being bigger than the anterior premolars. Finally, the incisors of the lower jaw have rounded crowns (Rosevear, 1965).

Lavia frons have a bluish gray body with some members having a lower back that is somewhat brownish or green. The wings are broad and the wingspan is about 14 inches (Rosevear, 1965). The color of its wings is a mixture of red and yellow and hence, Lavia frons is often referred to as the African Yellow-Winged bat. Its ears, like its wings, are reddish yellow. The ears contain a divided tragus that is relatively spiky. The eyes are quite large. In fact, Lavia frons has the second largest eyes of any African microchiroptera, second only to Cardioderma cor (Vaughan and Vaughan, 1987). The noseleaf of Lavia frons is distinctive in that it is enveloped by a pointed spike. Other physical characteristics include glands on males that secrete a yellow substance that discolors the lower back and a pair of false nipples near the anus of females.

Range mass: 28 to 36 g.

Range length: 58 to 80 mm.

Average wingspan: 36 cm.

Other Physical Features: endothermic ; bilateral symmetry

Habitat ( Inglês )

fornecido por Animal Diversity Web

Lavia frons occupies low-lying savannas and woodlands with open space. This species generally prefers areas where trees and bushes occur near rivers, swamps, or lakes. Apparently, trees near and around water provide sites for roosting. Lavia frons is usually seen roosting in Acacia tortilis trees at elevations below 1000 meters.

Range elevation: 1000 (high) m.

Trophic Strategy ( Inglês )

fornecido por Animal Diversity Web

Lavia frons are insectivorous. They eat a variety of insects ranging from grasshoppers to mosquitoes. Lavia frons can often be seen eating alate termites, which are readily available during the rainy season. They tend to forage near Acacia tortilis trees that attract insects throughout the year. Rather than searching for their food, these bats wait for insects to travel near their foraging perch and then attack them. They move to different foraging sites when insects are not available. In fact, Lavia frons moves every few minutes to a different perch to increase the chances of catching prey. Lavia frons attacks insects that fly as high as 20 to 30 meters above the ground to insects that fly as low as 1 meter above the ground (Vaughan and Vaughan, 1987). The attack is almost completely horizontal with the bat usually returning to its original perch to consume its prey (further information on foraging behavior discussed in behavior section).

Animal Foods: insects

Primary Diet: carnivore (Insectivore )

Lavia frons plays an important part in protecting Acacia tortilis trees by regulating insect population. Acacia tortilis trees are roosting sites for these bats. They flower in the dry season during the time from mid-December to February (Vaughan and Vaughan, 1986). This flowering attracts swarms of insects, which damage the leaves of the trees while trying to gain access to the flowers. By capturing and eating insects, Lavia frons helps prevent damage to the trees.

Many behavioral traits of Lavia frons have evolved in order to save energy. These include shifting perching locations in response to weather, monogamy (male and female Lavia frons expend much less energy in raising young when they are in a monogamous relationship), and the close relationship of the bats to Acacia tortilis trees.

Reproduction ( Inglês )

fornecido por Animal Diversity Web

Courtship rituals include a pair flying over each other and circling one another.

Mating System: monogamous

Members of Lavia frons are monogamous with members of a pair roosting together and engaging in courtship rituals, which include flying together and circling one another. The gestation period usually begins in January and lasts about three months with offspring being born in early April (there have also been reports of births in October and January; Vonhof,1999).

After birth, a young bat adheres to its mother by attaching its mouth to a pair of false nipples located near the mother's tail. To further insure attachment to the mother, the young bat wraps its legs around the back of its mother's neck. Despite the added weight of the offspring, the mother continues to forage. For roughly three months, the mother and its offspring stay in close proximity. During this time, grooming generally occurs with the mother eating the metabolic wastes of the baby in an apparent water conservation mechanism (Vaughan and Vaughan, 1987). In addition, the young bat observes the foraging and hunting techniques of its parents. The young Lavia frons hangs from its mother and practices flapping its wings until it begins flying by itself. At that point, the young bat is left alone.

Approximately 20 days after the young bat begins flying alone, weaning begins. For 30 more days, the young Lavia frons shares the territory of its parents (Vaughan and Vaughan, 1987). After this 30 day time period, the young bat is no longer solely dependent on its parents.

Breeding season: January-April

Average number of offspring: 1.

Average gestation period: 3 months.

Average weaning age: 55 days.

Key Reproductive Features: seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization (Internal )

Both male and female partners care for the offspring. The male protects the offspring while the female nurtures the offspring.

Parental Investment: altricial ; male parental care ; female parental care

Gelbflügelfledermaus ( Alemão )

fornecido por wikipedia DE

Die Gelbflügelfledermaus (Lavia frons) ist eine Fledermausart aus der Familie der Großblattnasen (Megadermatidae). Ihr Verbreitungsgebiet umfasst das mittlere Afrika und reicht von Gambia bis Äthiopien und südlich bis Sambia.

Beschreibung

Wie ihr Name schon andeutet, sind die Flügel dieser Fledermausart gelblich-rot gefärbt, ebenso wie die langen Ohren. Die Färbung des übrigen Körpers variiert von hellgrau bis graublau. Das Nasenblatt ist wie bei allen Großblattnasen sehr groß und endet darüber hinaus am unteren Ende in einer nach vorne ragenden Spitze. Diese Tiere erreichen eine Kopfrumpflänge von 60 bis 80 Millimetern, eine Flügelspannweite von rund 35 Zentimetern und ein Gewicht von 28 bis 36 Gramm.

Lebensweise

Gelbflügelfledermäuse leben in Wäldern und offenen, baumbestandenen Gebieten, meist in der Nähe von Gewässern wie Sümpfen, Flüssen und Seen. Im Gegensatz zu den anderen Großblattnasen bevorzugen sie Bäume als Schlafplätze, daraus ergibt sich, dass sie tagsüber sehr aufmerksam und relativ aktiv sind. Sie schließen selten die Augen und flattern immer wieder vor möglichen Gefahren davon.

Gelbflügelfledermäuse bilden im Gegensatz zu den meisten Fledermausarten monogame Beziehungen. Ein Männchen und ein Weibchen etablieren einen eigenen Ruheplatz, mindestens 20 Meter vom nächsten Pärchen entfernt, Das Männchen beschützt sein Weibchen, insbesondere in der Stillzeit, es fliegt immer wieder durch das 0,6 bis 0,8 Hektar große Territorium, um Artgenossen zu vertreiben und vor Fressfeinden (vorwiegend Greifvögel und Schlangen) zu warnen. Auch die gegenseitige Fellpflege wurde bei diesen Tieren beobachtet.

Nahrung

Im Gegensatz zu den anderen Großblattnasen sind Gelbflügelfledermäuse reine Insektenfresser. In der Abend- und Morgendämmerung, meist bei mehr Licht als viele andere Fledermäuse, begeben sie sich auf Nahrungssuche. Zu diesem Zweck hängen sie an Ästen und halten Ausschau. Haben sie ein Beutetier entdeckt, stürzen sie sich darauf und fliegen wieder zu ihrem Baum zurück, um es dort zu verzehren.

Fortpflanzung

Diese Tiere kennen Balzrituale wie gemeinsame Flüge, bei denen sich die Partner gegenseitig umkreisen. Im April, am Beginn der Regenzeit, kommt meist ein einzelnes Jungtier zur Welt. Das Neugeborene klammert sich an ein Paar Pseudozitzen in der Nähe des Afters und wird so bei den Streifzügen der Mutter mitgenommen. Nach rund einem Monat beginnt es mit selbstständigen Flugversuchen und wird rund 20 Tage danach entwöhnt. Anschließend hält es sich noch 30 Tage im elterlichen Revier auf, bevor es dieses endgültig verlässt.

Bedrohung

Gelbflügelfledermäuse sind häufig und weitverbreitet und werden nicht als bedroht gelistet.

Yellow-winged bat ( Inglês )

fornecido por wikipedia EN

The yellow-winged bat (Lavia frons) is one of five species of false vampire bat (family Megadermatidae) from Africa and is the only known species of its genus, Lavia.

Description

The yellow-winged bat has a total length of 58–80 mm (2.3–3.1 in)[2] and a body weight of 28–36 g (0.99–1.27 oz).[3] Females tend to be slightly larger than males. The wingspan averages 36 cm.[4] This specie's pelage is made of long hairs that are typically pearl grey or slaty gray. Males may have greenish-yellow fur on the hindparts and on the ventral surfaces.[5] As their name suggests, the bat has wings that are reddish-yellow which is also the color of their other membranes as well as their noseleaf and ears. The membranes are largely hairless although there is some fur on the upper arms.[5] The ears are fairly long and have a spiky tragus.[4] They have an elongated noseleaf with a blunt but pointed tip.[5] Although the yellow-winged bat has an advanced interfemoral membrane, it lacks an external tail. The dental formula is 0.2.1.11.2.3.3. Glands exist on the lower back of males and discharge a yellow substance.[2] Females have false nipples near the anus and are used by the young to hold on to.[6]

Ecology

The yellow-winged bat has an extensive range throughout sub-Saharan Africa south to northern Zambia. The bat mostly lives in woodland and savannah habitats and in elevations of less than 2,000 m.[5] They prefer acacia trees and thorn bushes near bodies of water,[7] around which they fly.[8] They prefer to live in areas where the vegetation is well spaced, which allows them to view more of their surroundings.[7] The yellow-winged bat primarily roosts in small trees and shrubs.[8] They can also be found roosting in trees cavities and buildings.[2] They will roost in two separate trees; a primary and a peripheral tree. Bats use their primary roost in the morning and again before evening.[9] Bats travel between primary and peripheral roost trees, especially on hot days, as they may need shade. These flights are typically short but longer flights have been recorded in midday.[9]

Unlike other false vampire bats, the yellow-winged bat feeds only on insects and not small vertebrates. They will feed on both soft- and hard-bodied insects.[3][9] Bats may feed on termites, scarab beetles, orthopterans, lepidopterans and dipterans.[3][9] The size of prey ranges from "very small to relatively large".[3] The yellow-winged bat is a sit-and-wait predator. They perch and listen for prey and if it flies by, the bat launches their attack. This species, while potentially vulnerable to predation, is very alert. Mambas, bat hawks, night tree vipers and common kestrels may prey on this species.[5]

Behavior and life history

The yellow-winged bat is a monogamous species. Males and females form pairs during the breeding season and establish their own foraging territories.[9] They are no more than 1m apart when roosting together. One member is vigilant during the day, and is able to turn its head 225° and move its ears. Between the foraging periods in the morning and evening, the male visits the peripheral roost, protecting it from potential intruders.[9] In the morning, the pairs interact with each other before splitting up for the day. The male and female meet again at the primary roost tree before evening to interact.[9] The maximum amount of male-female social interaction occurs between May and early June. This is when insects are more numerous and the young are able to hone their hunting skills.[6] The exact time at which the yellow-winged bat gives birth can vary by region; parturition occurs at the close of the dry season in October in Zambia, while at Lake Baringo in Kenya, it occurs the start of the so-called "long rains" in April.[5] Females are pregnant for around 3 months[3] with only one young being born. During the first few weeks, young hang on to their mothers.[6] Soon, the young stay at the roost for around a week and develop self-sustained flight.[5] Young are weaned when they are around 55 days old.[6]

Calls produced by this species include search-phase echolocation calls and some social calls that can be heard by humans.[5] Echolocation helps give the bat information on close objects.[9] Social calls are associated with aggression, copulation or mother-offspring interactions.[5]

Status

Little is known about human impacts on the population of the yellow-winged bat and the population dynamics of the species have not been recorded.[5] It does not appear to be particularly threatened but is likely not very common.[5]

Lavia frons ( Espanhol; Castelhano )

fornecido por wikipedia ES

El murciélago de alas amarillas (Lavia frons) es una de las cinco especies de falsos vampiros (familia Megadermatidae) de África.

Descripción

El murciélago de alas amarillas tiene una longitud total de 58 a 80 milímetros,[2]​ una envergadura de 36 centímetros en promedio y un peso de entre 28 y 36 gramos.[3]​ Las hembras tienden a ser ligeramente mayores que los machos.[4]​ El pelaje de esta especie está conformado por pelos largos de color gris perla o gris pizarra; los machos tienen pelo amarillo verdoso en las partes traseras y en el abdomen.[5]​ Como su nombre sugiere, este murciélago tiene alas de color amarillo rojizo, al igual que otras membranas, la nariz y las orejas. Las membranas carecen de pelos en su mayor parte, aunque sí presentan pelaje en la parte superior de las alas.[5]​ Las orejas son largas y puntiagudas, al igual que la nariz.[5]​ Aunque este mamífero tiene una membrana inferfemoral avanzada, carece de cola externa. Los machos tienen glándulas en la parte inferior y posterior y secretan una sustancia amarillenta.[2]​ Las hembras, por su parte, tienen pezones falsos en su parte trasera que ayudan a que las crías puedan sostenerse de ellas.[6]

Hábitat y alimentación

El murciélago de alas amarillas habita en una extensa zona de distribución que abarca la zona central de África. Se lo puede encontrar en Benín, Burkina Faso, Burundi, Camerún, la República Centroafricana, Chad, la República Democrática del Congo, Costa de Marfil, Eritrea, Etiopía, Gabón, Gambia, Ghana, Guinea Bissau, Kenia, Malaui, Mali, Níger, Nigeria, Ruanda, Senegal, Sierra Leona, Somalia, Sudán del Sur, Sudán, Tanzania, Togo, Uganda y Zambia. Su hábitat son los bosques y la sabana, en zonas con elevaciones inferiores a los dos mil metros sobre el nivel del mar.[5]​ Prefiere las acacias y los arbustos espinosos cercanos a las fuentes de agua,[7]​ en sitios donde la vegetación crece con amplios espacios entre sí, lo que le permite tener una mayor visión del territorio que lo rodea.[8][7]

Esta especie se establece sobre árboles pequeños y arbustos. También se los puede ver dentro de las cavidades de los árboles y los edificios.[8][2]​ Para armar su guarida, elige dos árboles separados: uno primario y otro secundario. El primario lo usa durante el día y antes de la noche.[9]​ Los murciélagos vuelan entre ambos árboles, especialmente durante los días cálidos, para recibir sombra; estos vuelos suelen ser cortos, pero se han registrado vuelos más largos en las horas del mediodía.[9]

A diferencia de otros falsos vampiros, este murciélago se alimenta solo de insectos y no de vertebrados pequeños.[3][9]​ Estos insectos pueden ser termitas, escarabajos, ortópteros, lepidópteros y dípteros.[3][9]​ El tamaño de las presas va desde "muy pequeñas a relativamente grandes".[3]​ Este murciélago es un depredador pasivo, que permanece inmóvil esperando a sus presas y las ataca cuando vuelan cerca suyo. Asimismo, puede ser presa de otros animales, como el milano murcielaguero, las serpientes de los géneros Dendroaspis y Boiga y el cernícalo vulgar.[5]

Estatus

La comunidad científica cuenta con escasos datos sobre el impacto de los seres humanos sobre la población de murciélagos de alas amarillas y no existen registros de la dinámica de la especie.[5]​ No parece tener una amenaza en particular, pero aun así no es un animal muy común.[5]

Lavia frons ( Francês )

fornecido por wikipedia FR

Lavia frons est une espèce de chauves-souris de la famille des Megadermatidae. C'est l'unique espèce du genre Lavia[1]. On l'appelle communément chauve-souris aux ailes d’or / dorées / orangées / jaunes ou Mégaderme aux ailes orangées.

Description

C’est une chauve-souris de taille moyenne, la femelle étant légèrement plus grande que le mâle. Le poids tourne autour de 30 g[2]. La longueur de la tête à la queue varie environ de 6 à 8 cm pour des avant-bras de 5,5 à 6,5 cm[3],[2]. Les oreilles, dressées vers le haut, sont longues[4]. La membrane du patagium englobe aussi les pattes. Le corps est gris bleuâtre, avec certains individus dont le bas du dos est quelque peu brunâtre ou vert. Les ailes sont larges et l'envergure est d'environ 30 cm[3]. La couleur de ses ailes est un mélange de rouge orangé et de jaune. Les oreilles ont la même couleur. Les yeux sont assez grands. Le nez singulier est en forme de datte pointue[4].

Cette chauve-souris chasserait (bien qu'occasionnellement) d'autres chauves-souris pour les manger[2].

Distribution

L. frons se retrouve plus ou moins dans toute l'Afrique centrale et de l’Ouest, de la Gambie à l'Éthiopie et au Sud jusqu'en Zambie en passant par le Kenya. Elle vit dans les savanes basses et les forêts claires et préfère généralement les zones où les arbres et les buissons se trouvent près des rivières, des marécages ou des lacs[3]. C'est davantage une espèce de plaine que d'altitude[2].

Liste des sous-espèces

Selon Mammal Species of the World (version 3, 2005) (23 septembre 2017)[5] et ITIS (23 septembre 2017)[6] :

  • sous-espèce Lavia frons affinis K. Andersen & Wroughton, 1907
  • sous-espèce Lavia frons frons (E. Geoffroy, 1810)

Lawia żółtoskrzydła ( Polonês )

fornecido por wikipedia POL
Commons Multimedia w Wikimedia Commons

Lawia żółtoskrzydła[3], lironos żółtoskrzydły[4] (Lavia frons) – gatunek ssaka z rodziny lironosowatych[5].

Systematyka

Takson po raz pierwszy opisany przez É. Geoffroy Saint-Hilaire'a w 1810 roku pod nazwą Megaderma frons[6]. Jako miejsce typowe autor wskazał Senegal[6]. Jedyny przedstawiciel rodzaju lawia[3] (Lavia) utworzonego przez J. E. Graya w 1838 roku[7].

Średnie wymiary

  • Długość ciała - 6,5-8 cm
  • Rozpiętość skrzydeł - 24-30 cm
  • Długość ogona - brak

Występowanie

Występuje w okolicach bagien, jezior znajdujących się w lasach oraz na terenach otwartych Afryki od Senegalu do Kenii.

Tryb życia

L. frons ma różną barwę sierści, ale ich skrzydła oraz uszy są zawsze ubarwione na żółtoczerwono. Śpią w krzewach lub na drzewach i tylko drżenie ich uszu zdradza ich obecność. Nietoperze te są aktywne całą dobę, latają w dzień, ale pożywiają się tylko w nocy. W przeciwieństwie do innych lironosów Lavia frons poluje tylko na owady. Poluje podobnie do muchówek czekając, aż owad sam znajdzie się w pobliżu, po czym zaatakuje go z góry.

Rozmnażanie

Poród tego gatunku nietoperzy nie jest związane z żadną porą roku, a samce pozostają we wspólnych noclegowiskach również w czasie rodzenia się młodych.

Lavia frons ( Sueco )

fornecido por wikipedia SV

Lavia frons[2][3] är en däggdjursart som först beskrevs av E. Geoffroy 1810. Lavia frons är ensam i släktet Lavia[4] som ingår i familjen storöronfladdermöss.[5][6] IUCN kategoriserar arten globalt som livskraftig.[1]

Inga underarter finns listade i Catalogue of Life.[5] Wilson & Reeder (2005) skiljer däremot mellan tre underarter.[4]

  • L. f. frons
  • L. f. affinis
  • L. f. rex

Utseende

Individerna blir 58 till 80 mm långa (huvud och bål) och saknar svans. De väger mellan 28 och 36 g. Pälsen har på ryggen främst en gråaktig färg, ibland med blå skugga, med undantag av regionen nära stjärten som kan vara brunaktig till olivgrön. På buken är pälsen ljusgul. Kännetecknande är de orangegula öronen och flygmembranen i samma färg.[7]

Utbredning och habitat

Denna fladdermus förekommer i Afrika söder om Sahara och fram till södra Kongo-Kinshasa samt södra Tanzania. Den vistas i låglandet och i bergstrakter upp till 2000 meter över havet. Lavia frons lever i öppna habitat som savanner eller områden med akacior eller buskar.[1] Arten hittas ofta nära vattenansamlingar.[7]

Ekologi

Individerna vilar i trädens håligheter eller sällan i byggnader och de bildar där inga flockar.[1] De är ofta aktiva på dagen. Arten jagar inga ryggradsdjur som flera andra storöronfladdermöss utan bara insekter.[7]

En hane och en hona lever som monogamt par och delar samma revir. När en främmande hane närmar sig jagas den vanligen iväg av hanen som ingår i paret. Platsen där paret vilar ligger ofta vid revirets gräns och så är det ibland bara 20 meter mellan viloplatserna av två par. Honan föder en unge före regntiden. Ungen klamrar sig i början fast i moderns päls. Efter cirka 55 dagar börjar den flyga självständig och ungefär 20 dagar senare slutar honan med digivning. Sedan får ungen en månad stanna i föräldrarnas revir innan den jagas iväg.[7]

Вызывающие наименьшие опасения
IUCN 3.1 Least Concern: 11378

Желтокрылый ложный вампир[1] (лат. Lavia frons) — вид рукокрылых из семейства копьеносых. Единственный представитель рода Lavia.

Описание

Как следует из названия животного, крылья этого вида летучей мыши окрашены в жёлто-красный цвет, так же, как и длинные уши. Окраска остальной части тела варьирует от светло-серого до серо-голубого цвета. Листовидный нос очень большой, как у всех копьеносых. Длина тела составляет от 60 до 80 мм, размах крыльев — примерно 35 см, масса тела — от 28 до 36 г.

Распространение

Область распространения вида охватывает территорию Центральной Африки от Гамбии до Эфиопии и к югу до Замбии.

Образ жизни

Желтокрылые ложные вампиры живут в лесах и лесных саваннах, чаще вблизи таких водоёмов, как болота, реки и озёра. В отличие от других копьеносых, предпочитают в качестве мест ночлега деревья. Днём они редко закрывают глаза, постоянно порхая.

В отличие от большинства видов летучих мышей животные выстраивают моногамные отношения. Самец и самка устраивают собственное место отдыха на расстоянии как минимум 20 м от другой пары. Самец оберегает самку, в частности, в период выкармливания детёныша, летая вокруг своего участка площадью от 0,6 до 0,8 га, и прогоняя сородичей и предупреждая о хищниках (преимущественно дневных хищных птицах и змеях). Также у этих животных наблюдалось взаимное ухаживание за шерстью.

Питание

В отличие от других копьеносых, желтокрылые ложные вампиры питаются исключительно насекомыми. В вечерние и утренние часы, чаще при бо́льшем количестве света чем у многих других летучих мышей, они отправляются на поиски корма. Поначалу они висят на ветвях и высматривают добычу. Когда они её находят, они бросаются на неё, хватают и снова возвращаются к своему дереву, чтобы там съесть свой улов.

Размножение

Эти животные используют ритуалы токования, такие как совместный полёт, во время которого партнёры кружатся вокруг друг друга. В апреле, в начале сезона дождей, на свет появляется чаще единственный детёныш. Новорождённое дитя цепляется за пару ложных сосков вблизи заднего прохода и таким образом перемещается вместе с матерью. Примерно через один месяц он начинает самостоятельные попытки полёта, и спустя 20 дней отлучается от матери. Затем ещё 30 дней он находится на территории родителей, прежде чем окончательно их покидает.
