The Brazilian ruby (Heliodoxa rubricauda) is a species of

endemic to Brazil.[3][4]

Taxonomy and systematics

The Brazilian ruby was described by the French polymath

type locality is Rio de Janeiro in Brazil.[8]

The Brazilian ruby was at one time the only species in the

Clements taxonomy and BirdLife International's Handbook of the Birds of the World retained it in Clytolaema.[11][12]

The Brazilian ruby's earlier generic name Clytolaema combined the

specific epithet rubricauda combines the Latin ruber meaning "red" and cauda meaning "tail".[13]

The Brazilian ruby is

monotypic.[3]

Description

The Brazilian ruby is 10.8 to 11.3 cm (4.3 to 4.4 in) long. Males weigh 7 to 9.2 g (0.25 to 0.32 oz) and females 5.9 to 7.1 g (0.21 to 0.25 oz). Both sexes have a medium length black bill and a white spot behind the eye. Adult males have an iridescent emerald green forehead and crown, a green nape, and a golden bronze back and rump. The chin is blackish, the

Melanistic morph individuals are frequent.[14]

Distribution and habitat

The Brazilian ruby is found in eastern and southeastern Brazil from Bahia south to Rio Grande do Sul. It inhabits the interior of forest, scrublands, parks, and banana plantations, and is frequently seen at feeders. In elevation it is most numerous below 500 m (1,600 ft) but ranges as high as 1,500 m (4,900 ft).[14]

Behavior

Movement

The Brazilian ruby is mostly sedentary but locally makes some seasonal elevational movements.[14]

Feeding

The Brazilian ruby feeds on nectar from a wide variety of flowering plants and trees, both native and introduced. Males often defend feeding territories and females sometimes do. They also capture small insects by hawking from a perch.[14]

Breeding

The Brazilian ruby's breeding season spans from November to March. It makes a cup nest of soft plant material with lichen on the outside and places it on a horizontal branch, typically 3 to 10 m (10 to 30 ft) above the ground. The female incubates the clutch of two eggs for 15 to 16 days; fledging occurs about 25 days after hatch.[14]

Vocalization

The Brazilian ruby's song is described as "jig chrrrrrr....jig cherrrrrr...jig chrrrrrr". It also makes a "jig jig jig" call.[14]

Status

The

IUCN has assessed the Brazilian ruby as being of Least Concern. Though it has a large range, its population size and trend are unknown. No immediate threats have been identified.[1] It occurs in several protected areas, and is "[c]ommon throughout [its] range...and readily accepts man-made habitats like tree-filled gardens, parks and plantations."[14]
