I regularly take brief glances out my fifth floor apartment window and look at the wooded wetland area there, and I most often do not see any birds, or other times I see 2 to 4 birds all of one species. But I noticed suddenly at 10:30 AM this morning that there were multiple birds in the trees outside our window, many more than we usually see. I looked with binoculars and was able to identify about five Eastern Phoebe‘s, about four black capped chickadee‘s, two hairy woodpeckers, one red bellied woodpecker, two robins, and one European starling. Do you have any theories about why there are usually zero or one bird out our window and suddenly in this half hour this morning there were so many different kinds of birds in the trees outside our window? And then a few minutes later, there are none again.
