Besides the avian attributes of flight, feathers and laying eggs, potoos are quite possibly the most unbird-like birds in the world. A Northern Potoo by Nick Athanas Northern Potoos are found from Mexico to Costa Rica and on the islands of Jamaica and Hispaniola. In reality though, this is actually a pretty stellar nesting strategy.

American Goldfinches are found in much of the United States all year round, spreading their range to Canada in the summer, and into the southern United States and Mexico in the winter. The cowbirds will try to lay their eggs in a goldfinch nest, but once hatched the young only survive a few days.

The nest is lined with grass, leaves and feathers, and will have up to four blue-green eggs with red spots. The dense prickly cactus aids in protection of the nest, making it very difficult to see in, let alone try to enter.

Especially when I compare it with the other cowbird present in central Mexico, the Brown-headed Cowbird. Instead, they lay their eggs in other species’ nests, and let those nest-making birds (often significantly smaller than the cowbirds) raise their young. Both (in fact, all) cowbirds are obligate brood parasites.
