Shiny Cowbird (Molothrus bonariensis) Science Article 6
Recent human settlement in Brasilia, Central Brazil, has greatly reduced the extent of native cerrado vegetation. This has favored the Shiny Cowbird, Molothrus bonariensis,which is common in farmland and certain urban sites. Between September and December of 1982 to 1984, we observed cowbird nestlings(n) or fledglings(f) attended by adults of Mimus saturninus (n), Thraupis sayaca (n), Thraupis palmarum (n,f), Cypsnagra hirundiacea (f), Hemithraupis guira (f), and Ammodramus humeralis (n).
