Many jays, including this California Scrub-Jay, store food for sustenance in harsher seasons. An individual bird may cache nuts, insects, and even worms in several thousand spots. If jays visit your yard, here’s a game you can play with them. Each day, preferably when the jays aren’t watching, place a dozen peanuts in different parts of the yard. They should be visible, but scattered. When a jay arrives, watch how long it takes to find the nuts. The next day, place the nuts in a different array and watch again. Do the jays find them quickly? They might already have a mental map of everything in the yard, so anything new — like a peanut in a novel spot — seems to jump out at them.More info and transcript at BirdNote.org. Want more BirdNote?
