Hi,I live in Arizona and I have 4 Mourning Doves with about 1 to 2 inch.white on the Tail. The Tail is also shorter than the normal looking Doves. Are this doves Leucietic? There is a all white Sparrow in my yard as well and 2 more Sparrows with white an the side of wings. I do not have a gread Camera but I have a Wildlife Biologist in the Fam. She said it is not normal to hanve so many Birds like this in one Yard.
