Appearance
The Puerto Rican vireo has a gray head, a white breast and a yellowish belly. The species measures, on average, 12 cm and weighs from 11 to 12 grams.Naming
From 1973 until at least 1996, the species suffered a population decline in the Guánica State Forest. The primary reason for this decline was brood parasitism by the shiny cowbird.Distribution
The Puerto Rican vireo is found in various forested areas of all elevations in Puerto Rico, in wet and dry forests, and mangroves. The birds have been found to be living in the various shade coffee plantations.Reproduction
Breeding starts from March to July where they lay clutches of 2–3 eggs, that are palish pink with brownish brown spot. Typically, the vireos usually only have enough resources to sustain one chick, and the parents share equal responsibility in caring for the chick by gathering resources and defending the nest from other birds.Food
An insectivore, the species's diet consists of grasshoppers, caterpillars, cicadas, beetles and aphids and is complemented with spiders, anoles, and berries.References:
