Bronzed Cowbirds are expanding their range (birdzilla) and can be found along the Mexican border and east along the gulf.

This is a male Bronzed Cowbird.  Love those eyes.

I have seen Bronzed Cowbirds mate in a very exciting display.

Like a bird of paradise, it hops from side to side and then elevates about three feet in the air and hovers like a hummingbird.

I couldn’t believe my eyes when I saw it.  I tried finding a video on YouTube without any luck.

This female Bronzed Cowbird has the look of a killer.  It pecks the eggs in the nest that it parasitized.

The highest number of Bronzed Cowbird eggs in a single nest is 14 (Cornell).

This egg was ejected out of a parasitized towhee nest by the towhee 10 days after being discovered.

The mark on the egg is most likely the result of a Bronzed Cowbird which pecks eggs in the host’s nest to boost the success rate of their own eggs.
