Guaiabero Parrot - Bolbopsittacus Lunulatus - Least Concern

The guaiabero is a species of parrot in the family Psittaculidae, belonging to the monotypic genus Bolbopsittacus and closely related to the lovebirds (Agapornis) and hanging parrots (Loriculus). It is endemic to the Philippines and locally known as bubutok.

Its common name is derived from its reputation for eating guavas.

Measuring around 15 cm (5.9 in) in length, it is a smallish, stout parrot with a large bill and stubby tail. The sexes differ in plumage. The adult male is green overall, with more yellowish underparts and a pale blue face and collar and wing primaries. The rump is yellow-green. The bill is grey-blue and with a darker tip, and the eyes dark brown. The adult female is also greenish, with a yellow collar and less blue on the face. It has black crescent markings on the nape and rump. Its bill is paler grey.

It inhabits lowland forests and adjacent cleared country. It is a predominantly fruit eating parrot, and has been recorded near fruit trees such as mangos. The breeding habits in the wild remained virtually unknown until a few years ago, but based on recent observations it appears to nest in a self-excavated cavity inside an arboreal ant nest or termite mound.
