Parula pitiayumi
The tropical parula (Setophaga pitiayumi) is a small New World warbler. It breeds from southernmost Texas and northwest Mexico (Sonora) south through Central America to northern Argentina, including Trinidad and Tobago. This widespread and common species is not considered threatened by the IUCN.
This passerine is not migratory, but northern birds may make local movements. For example, although it does not breed in much of Pacific Central America, it is a regular vagrant to countries like El Salvador.
It is 4.3 in (11 cm) long and has mainly blue-grey upperparts, with a greenish back patch and two white wingbars. The underparts are yellow, becoming orange on the breast. The male has a black patch from the bill to behind the eye.
Females are slightly duller than the males and lacks black on the head. The immature tropical parula is dull-plumaged, lacks the wing bars, and has a grey band on the breast.
The song is a high buzzy trill, and the call is a sharp tsit.
The tropical parula has about 14 subspecies, with a wide range of plumage tones. S. p. graysoni, is endemic to Socorro in the Revillagigedo Islands. Some subspecies (especially insular ones) are occasionally considered separate species.
Setophaga pitiayumi has occasionally been lumped with the closely related northern parula (S. americana) as a single species. Hybrids are routinely found in the Rio Grande Valley of southern Texas, though this may be a recent phenomenon. Most tropical parulas can be distinguished from the northern parula by their lack of white eye crescents, but this may be ambiguous in hybrids. One should also look for the distribution and extent of non-yellow coloration on the breast, and the extent of yellow below the cheek and on the belly.
