A small mountain hummingbird of Costa Rica and western Panama. It has a mostly black bill with a pink base to the lower mandible, a small white spot behind the eye, a glittering royal-blue crown, black face and nape, bright metallic green back and a blue-black tail. The throat is brilliant rosy coppery orange with golden-green sides, and there is a violet-blue patch on the centre of the breast (Wikipedia, general species account).
It is aggressive and dominant over most other hummingbirds. Males defend feeding territories while breeding, and both sexes defend them afterwards. Where flowers are too deep for its bill it takes nectar from holes made by bumblebees and flowerpiercers. In Costa Rica it breeds from August to January; the female alone builds a bulky mossy cup nest, 2–4m up at the end of a hanging bamboo stem or on a rootlet under a bank, and incubates the two eggs. In at least parts of its range it moves downslope after breeding (Wikipedia, general species account).
On this guide it is a target species of Monteverde, Poas, Irazu, the Savegre Valley and Chirripo.
