@eric How do you keep track of the number of individuals you see like that?
I usually have a bunch of tufted titmice, black-capped chickadees and dark-eyed juncos flitting in and out of the trees in my back yard, but I can’t tell them apart well enough to know if I’m double-counting them.
@pganssle When I'm stationary, it's basically the max that I can see at one time. If you can distinguish male from female birds, that helps to know you're not double counting.
