Greenish Puffleg

A small, greenish hummingbird of humid Andean forests in Colombia, Ecuador, and Panama, greenish pufflegs are named for the distinctive white fluffy leg puffs — feather tufts on the tarsi — shared by all members of the puffleg genus Haplophaedia. They inhabit forest edges and secondary growth at elevations of 800–2,100 meters, foraging for nectar at small flowering plants in the understory. Listed as Least Concern with relatively stable populations across their range.
