The orange nectar bat (Lonchophylla robusta) is a species of bat in the family Phyllostomidae. It is found in Colombia , Costa Rica , Ecuador , Nicaragua , Panama , Peru , and Venezuela . Orange nectar bats in Costa Rica were observed utilising a unique feeding mechanism that has not been seen in any other animal, allowing them to pull liquid ...
A pellet, in ornithology, is the mass of undigested parts of a bird's food that some bird species occasionally regurgitate. The contents of a bird's pellet depend on its diet, but can include the exoskeletons of insects, indigestible plant matter, bones, fur, feathers, bills, claws, and teeth. In falconry, the pellet is called a casting.
The undigestable portions of prey are regurgitated in the form of pellets as in all owls. Pellets of the Eurasian eagle-owl average around 75 mm × 32 mm (3.0 in × 1.3 in), thus they are around the same size as those of most other large Bubo owls, even the notably smaller great horned owl (B. virginianus). In some cases, pellets of Bubo owls ...
Like hummingbirds, fruit bats and nectar bats hover over flowers while feeding on fruits or nectar. Comparison between bats and hummingbirds has revealed that these animals exert similar amounts of energy relative to body weight during hovering: hummingbirds can twist their wings more easily and are more aerodynamic, but bats have bigger wings and larger strokes.
Like other bats, leaf-nosed bats are nocturnal foragers that use echolocation to locate food sources, though the food sources vary between species. [14] Many bats in the family Phyllostomidae appear to have limited reliance on echolocation, likely because frugivorous bats do not need to quickly identify flying insects like many other bats. [ 8 ]
The pellets are typically grey coloured and are found in groups under trees used for roosting or nesting. At least some tawny owl pellets can measure up to 84 mm (3.3 in) long and can include large objects such as an intact 10 cm (3.9 in) bill of a snipe. [7] [1] [29] [32] Undigested material coughed up often reveals different prey than pellets ...
It has a forearm length of 40–47 mm (1.6–1.9 in). The fur on its back varies in color, ranging from an intense orange to brown. Its belly fur is tawny olive in color. It is extremely similar in appearance to the orange nectar bat (Lonchophylla robusta) and Handley's nectar bat (Lonchophylla handleyi), sympatric members of its genus. [2]
Lonchophylla concava was described as a new species in 1914 by Edward Alphonso Goldman.Goldman had collected the holotype from eastern Panama in 1912. [3] In 1966, Handley published that L. concava was a synonym of Goldman's nectar bat (L. mordax); [4] this was maintained until a 2005 publication asserted that there were major physical difference between the two taxa, and thus L. concava ...
