Genus Chaetocercus are 'woodstars', which are tiny hummingbirds that resemble a large bumblebee when flying. |
On male and female note buff, not white, stripe around neck, and small size. |
Large for a tiny woodstar, and found where it is cold, over 2500 m. (but much lower in Peru). A bad photo that shows how woodstars lift their tail up and down to hover. Good female flight shot. |
