Common Ground-Dove Columbina passerina


Description

The Common Ground-Dove is barely larger than a sparrow and is North America's smallest dove. It is a fast flyer with rapid, short, wing beats; similar to that of a quail. When it walks, it bobs its head like a pigeon. The Common Ground-Dove forages on the ground for seeds, small berries, and occasionally insects. Although this bird may be found in small groups, it's more typically found in pairs.
