After seeing a great photo of a bluejay carrying three acorns in its beak (in a recent post by Mike Powell) I thought I would do a little experiment in the backyard to find out whether squirrels or birds would be the first to find a new supply of acorns. I positioned a half dozen acorns around the yard in plain sight, and started my timer.
But apparently, not all acorns are equally attractive, and the kind I picked up were too big or too distasteful to attract attention.
The red squirrel barely gave my acorn a glance before moving off to find other goodies.
The bluejay gave it a really good look, first with one eye and then with the other. I wonder if this head tilting behavior to inspect potential food means that they don’t really have binocular vision?
Hmm….not my type.
The twins were less than impressed. The one on the right gave the acorn (sitting conspicuously on a rock at nose level) a sniff, but couldn’t get away fast enough.
Well, so much for my backyard experiment. All of the acorns are still in position. Yet, acorns are a part of the diet of all three of these species. They must have been inferior quality. Rejected!
