I heard a lot of commotion outside my window earlier this week and the cat was more interested in that particular area than usual. As I suspected, the robin eggs have hatched. I hate to say it, but these birds are pretty freaking ugly when they first hatch. Unlike ducklings and chicks, robins and other similar birds hatch out at an early stage of development, which is due to their nesting in trees Ducks and hens nest on the ground, necessitating that they hatch in a much less helpless state due to predators. So, ground nesting birds incubate their eggs a little longer so that, when they hatch, the babies are strong enough to follow the mother out of the nest. It also results in them looking cuter.
