The Puerto Rican bullfinch has black feathers with orange areas above the eyes, around its throat, and underneath the tail's base.
[2] Bullfinches are considered to be mainly frugivorous (and appear to prefer fruit when available) but they also consume other plant and animal material.
Because of their behavioral flexibility when it comes to food consumption, foraging methods, and foraging site preferences, they are considered a generalist species 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 (6) (7).
However, in the dry forests of southwestern Puerto Rico, most species restrict their breeding to the spring and early summer rainy season of approximately late April to July.
During the dry season from December to April, resources are probably too limiting for birds to successfully rear young in most years (5).
Therefore it might be possible that bullfinches and other species attempt to breed again during the shorter annual rainy peak in September and October (5).
The Puerto Rican bullfinch has been observed exhibiting cooperative breeding behavior in the Guanica region.
All species of the genus Melopyrrha, which is endemic to the Caribbean, are described as constructing domed or globular nests and laying clutches of 2–3 dull greenish eggs with dark markings (10).
Other possible next predators include red-legged thrushes (Turdus plumbeus), Puerto Rican racers (Borikenophis portoricensis), anoles (Anolis spp.
Nets success is believed to be higher when there is more fruit availability, increased precipitation and decreased nest height (5).
