We’ve been watching the evolution of a Dark-Eyed Junco nest as its been parasitized by a Cowbird. We believe that two of the Junco eggs have been eaten and replaced by two Cowbird eggs at different times. One of the Cowbird eggs has hatched.

    I highly dislike brown-headed cowbirds. What lazy (but opportunistic) parasites! >:( It’s also a shame that the other bird species suffer as a consequence.

    I found a cowbird egg in a Chipping Sparrows nest with three eggs. The tiny nest had littlw room for the sparrows if they were to hatch and I new they would be ejected or starve. I removed the cowbird egg?
