Yes, hummingbirds remember, even though I, a simple human, do NOT remember where I put my biggest and best hummingbird feeder when I was done with it last year.
Last weekend when Joanna and Boo and I were visiting in my living room, we witnessed one of my early hummingbird arrivals.
Ever since last week when I saw my first hummer, I have been looking in vain for two of my feeders. My MAIN feeders. Good grief, where would I have put them, and why didn't I put them in the garage with the other two?
Anyway. Today I glanced out toward the front porch and saw a hummingbird circling the spot where I had my best feeder last year. There was no feeder there, but he was circling as though he was looking for it.
He surely must be a return visitor; otherwise, why would he even be looking for nectar in that spot?
I hunted up a substitute feeder to hang in that spot, and he and his buddies are already fighting over it.
