Grey-chinned hermit

The grey-chinned hermit (Phaethornis griseogularis) is a species of hummingbird in the family Trochilidae. It is found in Brazil, Colombia, Ecuador, Peru, and Venezuela.

The nominate P. g. griseogularis and P. g. zonura subspecies of grey-chinned hermit are 8 to 10 cm (3.1 to 3.9 in) long; males weigh 1.8 to 2.5 g (0.06 to 0.09 oz) and females 1.9 to 3 g (0.07 to 0.11 oz). P. g. porcullae is about 10.5 cm (4.1 in) long and weighs about 2.5 g (0.09 oz). It also has longer wings than the other two subspecies. All three subspecies have generally greenish upperparts, a cinnamon red rump, and dark tail feathers with white tips. Males have a grayish throat and cinnamon red underparts, often with a black band across the chest. Male P. g. zonura is paler than the nominate, with more grayish underparts and a more decurved bill. P. g. porcullae is even paler than the other two subspecies and has more white in the tail. Females of all three subspecies are paler versions of the males.
