Shiny Cowbird

 The shiny cowbird male is black with a purple-blue iridescence. The female is smaller, has a dull-brown plumage and often paler on the underparts.

They are found in much of South America, but absent from a significant swath near the west coast of South America and a portion of the Amazon Basin.

There are seven subspecies. I saw the subspecies aequatorialis in Ecuador last year, near Churute Mangroves, all males, and I saw the subspecies cabanisii this year in Colombia at Tinamu Reserve, all females and juveniles.

  1. A weird name. The juvenile is more attractive than the adult.
