Shiny cowbird

Molothrus bonariensis

The shiny cowbird is a passerine bird in the New World family Icteridae. It breeds in most of South America apart from the most dense jungles, mountains and deserts, the coldest southernmost regions, and on Trinidad and Tobago. It has relatively recently colonised Chile and many Caribbean islands, and has reached the United States, where it is probably breeding in southern Florida.
