Editor’s Note: Additional distribution information for this taxon can be found in the ‘Subspecies’ article above. In the future, we will develop a range-wide distribution article.
Habitat
Forest and forest edge, secondary growth, clearings with scattered trees, orchards, and mangroves.
Diet and Foraging
Guaiabero seeds and fruit, fruits of vines and cultivated trees including guava, from which its name derives; forages along with vines and limbs of trees. Generally found feeding below 1000 m.
Sounds and Vocal Behavior
Guaiabero Calls include high-pitched short thin whistles, given either singly or in short series, such as “tsee” or “tse-tsee-tseet”. In the latter case, sounds like a short song strophe of a passerine.
Breeding
Starting to reach a breeding condition in Mar.
