I’ve got a small hummingbird feeder on the back balcony, next to the room where I’ve turned into my office.
Young Anna’s hummingbirds (and the occasional adult) use it regularly, draining it every few days. There’s usually one that sits on the tomato trellis and guards it, but they trade the role around every few weeks.
When the feeder gets low and I have the door open, one hummingbird flies in about two meters, hovers loudly until it has my attention, then turns around and flies back out, ostentatiously dipping its beak once in the empty feeder before it leaves the area.
I know my cue: I clean the feeder, put more sugar water in, and put it back out, and a happy hummingbird comes by in a few minutes to suck down on the fresh sugar. I’ve done this five times now in the last few weeks.
Obviously, cats know how to point at things, but it’s interesting to see the same behavior in something whose body is smaller than the cat’s brain. It doesn’t take much of a brain to be smart, does it?
So far as I can tell, only one bird has figured out how to tell me to change the feeder. It will be fun to see if any of the others learn the trick.
Is this social genius, or problem-solving genius? Or both?
Compare this with the dumb hummingbird, who got trapped in the same room a couple of months ago. He flew in through the open door, and I found him sometime later buzzing around the white ceiling. Did he think it was the sky? He buzzed around, poor little beak touching the ceiling, unwilling to drop even a foot down and go out the door. I lured him out by raising the feeder up to where he could see it, near the wide open door. Once he started drinking from it, I slowly lowered through the door. Once he was outside, he immediately flew away. I don’t know why he didn’t fly back out the door, or why he saw a white ceiling as a blue sky, but he panicked and got stuck.
There you have it. There are smart hummingbirds, and there are dumb hummingbirds. Natural variation on the back balcony.
I’m not sure how to photograph the smart one doing his thing. That’s the next puzzle.
