Do you have brood parasites in your yard?

If you have cowbirds, it may be tempting to take their egg from a nest you have found. Cowbirds, if you don't already know, lay their eggs in another bird's nest, forcing the host mom to feed it. The mother doesn't know any better, she follows her instincts. But sometimes the cowbirds are bigger than the host baby birds and can hoard food--starving other nest babies. Birds hate them. But if you see a nest with a weird egg, do not remove it. I found this article on another backyard bird page. It's interesting. tap the picture below for the article.
