The Anna’a Hummingbird is Evergreen State College’s smallest year round resident bird, and most common hummingbird.

Males have a brilliantly iridescent pink throat and head due to large stacks of melanosomes in their feather barbules, arranged in layers separated by keratin (Giraldo 2018). Both sexes have shining green back and sides.
