The Marvelous Mourning Dove
You can see Mourning Doves nearly anywhere in temperate parts of North America except the deep woods. Most migrate along flyways over land. Spring migration is north around April and Fall migration is south about October. Mourning doves almost exclusively eat seeds, which make up more than 99% of their diet. They generally eat enough to fill their crops and then fly away to digest while resting. They often swallow grit, such as fine gravel or sand to assist with digestion. Mourning Doves eat roughly 12 to 20 percent of their body weight per day.
Mourning doves are prolific breeders. In warmer areas these birds may raise up to 6 broods in a season. This fast breeding is essential because mortality is high. The average lifespan is 1.5 years, but if they survive their first year they can live 5 or more years. The oldest known Mourning Dove was a male and at least 30 years old when he was shot in Florida in 1998. He had been banded in Georgia in 1968.
