Амазилія-берил тобазька Saucerottia tobaci

Fairly common and very territorial small hummingbird. Glittering green head and underparts, coppery rump (absent in northwest mountain subspecies), bronzy to rufous brown undertail, slightly curved and medium-sized bill with red lower mandible, and forked blue tail. Female similar to male but with dull brown belly. Usually in forest edges, second growth woodland, and gardens. Flight call a trill; song a slow, high-pitched four-note “e-ri-caa.” Distinguished from Steely-vented Hummingbird by lack of blue rump coverts; from male emeralds by longer and more curved bill; and from Blue-chinned Sapphire by forked (not rounded) tail and lack of bluish tinge on chin and body.
