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. source
