Jack and the Corvid Clean-up Crew - UPDATE October 2, 2022

One-eyed Jack

A highlight today was seeing One-Eyed Jack again today. He sat in his spot as I opened Oats n Honey Granola Bars for him and crunched them up to make them easier for him to chew. He had trouble with hard hazelnuts earlier. After about a dozen bars, he said it was time to go and wandered off in no hurry, stopping to eat grass several times. I followed him at a distance because I don’t know how many times he will come back again this year, and I wondered where he was headed. The picture is of him stopped, eating grass and hearing the camera click.

With bears absent most of the day, the Corvid Clean-up Crew can swoop in and make sure nothing goes to waste. It consists of about 30 crows, less than a dozen ravens, and a dozen or so blue jays, all members of the family Corvidae. Watching them, they seem so aware. I looked them up on Wikipedia, which said Corvids display remarkable intelligence for animals of their size, and are among the most intelligent birds thus far studied.[5] Specifically, members of the family have demonstrated self-awareness in mirror tests (European magpies) and tool-making ability (e.g. crows and rooks[6]), skills which until recently were thought to be possessed only by humans and a few other higher mammals. Their total brain-to-body mass ratio is equal to that of non-human great apes and cetaceans, and only slightly lower than that of humans.[7]
