GABO,

I took a look at the website that Earl Horn mentioned that showed the picture of the male Shiny Cowbird and the immature Shiny Cowbird. It did not have a picture of the female, so I looked it up in a book called Birds of South America. The female Shiny Cowbird looks a lot like the female Brown Headed Cowbird, but maybe a shade or so lighter brown gray. If this is the only distinguishing field mark it would be very difficult to identify this species without it being a male. Does anyone know if there are visible field marks or behavior that would separate the female and immatures of these two species? Does the female or immature have different calls that could distinguish the two?

Any information would be appreciated!
