Apple #454: Mourning Doves

Don't feel much like talking today.

I took a few photos of some mourning doves in the woods a couple weeks ago.  Here are the photos and some facts about them.

• Mourning doves are the most common type of dove in the United States.

• They are also the most widely hunted game bird.

• They have been clocked at flight speeds in the 40 to 55 mph range.

• Their call is distinctive and familiar: coo-OO-oo, oo, oo.  The sound is a bit mournful; hence their name. 

• This is the male's call and it is used to mark territory or to court females.

• Females on the nest make a different call which sounds like ohr, ohr.

• Studies suggest that they mate for life.

• Mourning doves make their nests in evergreen trees and typically lay two eggs per brood.  But they have six broods in a year, which makes them sort of like the rabbits of the bird world.

• One egg is laid in the evening, the second the next morning.

• The food they feed their young, called "pigeon milk" or crop milk, is secreted by the lining of their crop.  It has more protein and fat than either cow's milk or human milk.  It looks and smells like cottage cheese.

• The hatchlings get crop milk exclusively for the first three days of their lives, and then they are slowly transitioned to seeds.

• Mourning doves live mainly in open, grassy areas.  

• They like to sit on telephone poles or wires. 

• They like to eat the seeds of wheat and buckwheat and common weeds.  They can often be seen walking on the ground picking up seeds. They are not shy of feeders.

• Most birds' feet have special adaptations to make them resistant to freezing.  Mourning doves, however, often lose several toes due to winter freezing.  This makes it difficult for them to scratch for seeds.

• When startled, they will burst into flight.  Their wings make high-pitched whistling noises.

By the way, this step-by-step search from Whatbird.com is really helpful.  If you know a few details about a bird, like its color and a general idea of its habitat, you can narrow the field down to a few choices and see which ones most closely resemble the bird you saw.
