About Phaethornis anthophilus (Bourcier, 1843)
The pale-bellied hermit (scientific name Phaethornis anthophilus (Bourcier, 1843)) is a medium-sized hermit hummingbird. It is approximately 13 cm (5.1 in) long. Males weigh 4.5 to 5.5 g (0.16 to 0.19 oz), while females weigh 4 to 5 g (0.14 to 0.18 oz). It has dark green to olive green upperparts and light gray underparts. Its face features a black "mask", a buffy supercilium, and a mostly white throat. The male's bill is almost straight, and the female's bill is decurved. The subspecies P. a. hyalinus has more bluish green upperparts and paler underparts than the nominate subspecies. Individuals belonging to the suggested subspecies P. a. fuscicapillus have shorter wings and bills than other members of the nominate subspecies. The full nominate subspecies as currently treated is distributed across central Panama; northern, central, and eastern Colombia; and western and northern Venezuela. The suggested P. a. fuscicapillus corresponds to the population found in Colombia's Eastern Andes, and may also include the Venezuelan population of the species. P. a. hyalinus occurs only on the Pearl Islands off the Pacific coast of Panama. The pale-bellied hermit primarily inhabits semi-deciduous forest. It can also be found in drier woodland, secondary forest, gallery forest, plantations, and brushy, thorny landscapes. It occurs at elevations ranging from sea level to approximately 1,500 m (4,900 ft).
