Its time to get knee-deep into some hummingbird knowledge with green-crowned brilliant facts.

These hummingbirds are a comparatively large species with a slender body, small black beak, short forked tail, and black eyes. The male is bigger and has a more vibrant and glittery shade of green on its back, throat, and breast. The female is duller and has white spots all over her underparts.

The green-crowned brilliant bird (Heliodoxa jacula) is a solitary resident breeder of the Costa Rican and western Ecuador highlands and cloud forest. These birds can be found between an altitude range of 2,300-6,600 ft (701-2,011.6 m), especially on the Caribbean slopes.

During the breeding season, the female builds a bulky, cup-like nest that clings on top of slim, drooping branches. She lays two eggs and incubates them alone while the male defends the territory.

The green-crowned brilliant (Heliodoxa jacula) is a herbivore and feeds on nectar-producing flowers. Marcgravia, Heliconia, and other large flowers are known as the preferred delicacies of this species.

These birds also have a squeaky call that sounds something like 'kyew'. In addition, the IUCN has declared that these birds are not vulnerable and they have been given the Least Concern status.

 Although their population is on the decline, the IUCN has given this species the Least Concern conservation status.
