Examples of avian species that were observed within anthropogenic habitats and either fed, roosted, or both within villages and farms include the smooth-billed ani (Crotophaga ani), common nighthawk (Chordeiles minor), white-collared swift (Streptoprocne zonaris), Pacific hornero (Furnarius cinnamomeus), lemon-rumped tanager (Ramphocelus icteronotus), swallow tanager (Tersina viridis), blue and white swallow (Notiochelidon cyanoleuca cyanoleuca), blue-black grassquit
(Volatinia jacarina), shiny cowbird (Molothrus bonariensis aequatorialis), turkey vulture (Cathartes aura), black vulture (Coragyps atratus), cattle egret (Bubulcus ibis), and a variety of members of the Tyrannidae family (flycatchers) and Troglodytidae (wrens).
The host species were the Bananaquit (Coereba flaveola), Antillean Elaenia (Elaenia martinica), Lesser Antillean Bullfinch (Loxigilla noctis), Streaked Saltator (Saltator albicollis), Black-faced Grassquit
(Tiaris bicolor), and the Black-whiskered Vireo (Vireo altiloqaus).
Analyzing the sequence of DNA extracted from blood samples taken from 13 of 14 Darwin's finch species, the scientists found that the birds shared the same evolutionary source as that of the grassquit
, a dull-colored sparrow found widely in Central and South America.
The Blue-black Grassquit
Volatinia jacarina (Linnaeus, 1766), popularly known in Brazil as "tiziu", is an inhabitant of open areas, and also common near cities (Marcondes-Machado, 1988).
