Going on mid-April, and no Mourning Doves seen migrating/nesting into my SE Colo area. Over the past four years, I have watched a Eurasian dove pair, 2006, expand into a 19 bird flock in spring 2010. They love one particularly knarly cottonwood in my area. And that's only one tree! Anyway, I'm worried, the Mourning dove is indigenious to my area, Eurasians are not, have you seen any Mourning doves migrating/nesting , in your area, or just Eurasians??? Colorado is very liberal on Eurasian Collared hunting bag limits, if this population increase into the west continues, maybe we need to, as hunters/conservationist, focus on reducing the Eurasian Collared numbers during dove season.
Keep your eyes to the dove skies!
