Puerto Rican mango

Appearance

The Puerto Rican mango is 11 to 12 cm long; males weigh 4.8 to 7.2 g and females 4.0 to 6.4 g. The male's upperparts are shiny bronze-green. It has green flanks, a dark brownish gray belly, and a bronzy green tail. The female's upperparts are also shiny bronze-green and its underparts are grayish lightening to pale white on the abdomen. It has a brownish gray tail with broad black marks near the end; the outermost feathers have white tips.

Distribution

The Puerto Rican mango is found on Puerto Rico, its offshore island Culebra, and the British and American Virgin Islands. It is apparently extirpated from the Puerto Rican island of Vieques.

Status

The IUCN has assessed the Puerto Rican mango as being of Least Concern, though its population is not known and is believed to be decreasing. It is considered generally common in coastal areas. It has been extirpated from some small offshore islands.

Habitat

It is found almost entirely in lowlands below 250 m, where it occurs in gardens and forest edges.

Reproduction

The Puerto Rican mango's breeding phenology has not been studied; most information is anecdotal. It is believed to breed at any time of the year and perhaps twice a year in Puerto Rico. The nest is a cup of soft plant fibers bound with spider silk and covered on the outside with lichens and bark flakes. It is usually placed in a tree or shrub and in Puerto Rico has been found on human-made substrates such as power lines, antennas, and fences. The clutch size is two eggs. The incubation time has been reported to be about 15 days with fledging 22 to 25 days after hatch.

Food

The Puerto Rican mango feeds on both nectar and arthropods, though details are not well known. It takes nectar from a wide variety of flowering plants and males defend nectar-rich territories. Insects are mostly taken on the wing and spiders from leaves and bark. It forages as high as 20 m above the ground.
