[cobirds] White-winged Doves, Colo Spgs,

I had WW Doves here all winter and I feel sure they nested somewhere in my neighborhood but I couldn't find them.  They are still here and I am pretty sure some are young ones.  I observed four at the feeder yesterday. As long as I put out seed, they come.  The Eurasion Collared Doves chase them off and empty the feeder fast - expensive to keep up.  Are they becoming as common as the EC Doves?
