I had a new visitor today.
When the blue jays come visiting, all the other birds scatter. What makes me laugh is the that the blue jays seem to be more afraid of the others. I have pair in the neighborhood that make regular visits to my feeders.
First one swoops down, grabs a peanut the flits out. Then the other repeats the procedure. After a few rounds of pairs diving, they start to get picky about which shells to grab.
Each successive swoop, they stay longer. They pick up a shell, shake it, then toss it over board. They repeat until they find one matching their criteria.
I do not know what their criteria are, other than weight, or maybe balance. I never had to fly with food in my mouth, so I would not know. Actually, I never had to fly.
Guess who eats the rejects?
