I was a little surprised by a pair of Eur. Collared Doves this morning building a nest from 8-9 am, in 32 F...
Birds of North America online says they breed from February to October, but will do so year-round in warmer climates. I know we had a warm fall, right into November, but lately it hasn't been so warm. The winds had died down finally (for 6 hours or so, as it turned out), so maybe it felt downright balmy & got them twitterpated for a spell... They were on the south-facing (sunny) side of a spruce, so maybe the micro-climate there added to their confusion? Our new Second CO Breeding Bird Atlas indicates breeding between late January thru the end of August. I haven't taken a close look to see what progress they made, but after more than a dozen trips I witnessed by the presumed male with single 4-6" pieces of grass stem, they seemed to stop the activity. Either came to their senses, or finished the job?? I'll have to look more closely tomorrow.
