Emerald-chinned hummingbird Abeillia abeillei

Very small, short-billed hummingbird of humid evergreen and pine-evergreen forest in highlands and upper foothills; uncommon. Usually feeds low, often at banks of flowers along edges and roadsides. Feeding flight is usually quick and hard to follow. Best identified by small size, big white spot behind eye, and rather liquid twittering call (similar to Stripe-tailed Hummingbird, which occurs in the same areas but looks quite different).
