Puerto Rican Bullfinch

The Puerto Rican bullfinch has black feathers with orange areas above the eyes, around its throat, and underneath the tail's base. The species measures from 17 to 19 cm (6.7 to 7.5 in) and weighs approximately 32 grams (1.1 oz).

Bullfinches are believed to be most common in dense mountain forests but can also be found in lower forests with dense undergrowth, coffee plantations, thick brushy areas, dry coastal thickets, and rarely in mangroves. They have also been described as edge or open-canopy species. Even though it has a widespread distribution over the island, it is suspected that there has been a reduction in range and overall population.

Bullfinches are considered to be mainly frugivorous (and appear to prefer fruit when available) but they also consume other plant and animal material. Even though the diet of the nestling bullfinches is unknown, most frugivorous bird species feed large quantities of animal matter to their young, especially during the early portion of the nestling stage. In later stages of development, it is likely that the chicks are also fed fruit and insects. Because of their behavioral flexibility when it comes to food consumption, foraging methods, and foraging site preferences, they are considered a generalist species.
