Antillean crested hummingbird Orthorhyncus cristatus

A perky, inquisitive inhabitant of woodlands, scrub, parks, and gardens. Note the mohawklike crest (except on young males), the rather short bill, and dark gray (adult males) to dingy (immatures and females) underparts. The female Puerto Rican Emerald lacks a crest, is often whiter below, and has a blackish face. The female Blue-headed Hummingbird also lacks a crest plus it has a longer bill and a longer tail that is blue. Calls include a high thin “pit” or “tsit” as well as various high-pitched twitterings.
