Black-chinned Hummingbird
Archilochus alexandri
ORDER: Caprimulgiformes
FAMILY: Trochilidae
During migration, individuals rarely remain longer than one day at a feeder even when food is scarce.
The Black-chinned Hummingbird’s tongue has two grooves; nectar moves through these via capillary action, and then the bird retracts the tongue and squeezes the nectar into the mouth. It extends the tongue through the nearly closed bill at a rate of about 13–17 licks per second, and consumes an average of 0.61 milliliters (about a fifth of a fluid ounce) in a single meal. In cold weather, may eat three times its body weight in nectar in one day. They can survive without nectar when insects are plentiful.
