The Morning Dove is commonly a ground feeder, walking about like a domestic Pigeon picking up food. It consumes many weed seeds and grass seeds. They will also eat blueberries of various kinds. Typically the bird will make a long-drawn, moaning coo that is heard more frequently in the Spring. This is the mournful sound that gives the bird the name of Mourning Dove. The Mourning Dove will lay two eggs in a depression on the ground but in general, it builds a skimpy nest of twigs in a tree.
