What kind of bird is black white and gray with webbed feet?

well, there are allot of birds that have gray feathers. i have a baby bird in my backyard that has gray feathers. robins can, sparrows, and doves are the main ones. very rarely newborn bluebirds can have grey feathers. if you want to know the specific bird, check the eggs (if there are any). if the eggs are blue, it is a bluebird or robin. any other color you would have to go deeper. sometimes you can't just tell by the eggs and the feathers. you can "spy" on the nest to see the mama.
