We had a pair mating earlier, and they have stayed around, but I never found a nest. I am fairly certain that I had an immature hummer in the yard last night. I am not up on what time of the season you can expect to see fledglings. Is this with in the window for fledgling hummers to appear? My martins have not left yet. They spend little time here now other than roosting, now that fledging has taken place. I have not brought the house down to look, but I think I only had two nest this year. I had 8 adult birds, fewest ever, and I think 4 fledglings. I had a flock of mixed blackbirds come to roost last night, in the flood control pit/nice small piece of marsh behind our place, that may have been enough to show on a radar. Scott Marsh Lexington KY
