What a lovely video (how research was funded? Not gonna go there!).
My favorite bird is their corvid cousin the bluejay with its many (22?) distinct warning calls. Can’t find the source, may have been Cornell ornithology, but it’s also fascinating. Thanks for posting. Cheers!
BLUEJAYS
Now there is more to a bluejay than any other animal. He has got more different kinds of feeling. Whatever a bluejay feels he can put into language, and not mere commonplace language, but straight out and out book talk, and there is such a command of language. You never saw a bluejay get stuck for a word. He is a vocabularized geyser. Now you must call a jay a bird, and so he is in a measure, because he wears feathers and don’t belong to any church, but otherwise he is just as human nature made him. A bluejay hasn’t any more principle than an ex-congressman, and he will steal, deceive and betray four times out of five; and as for the sacredness of an obligation, you cannot scare him in the detail of principle. He talks the best grammar of all the animals. You may say a cat talks good grammar. Well, a cat does; but you let a cat get excited, you let a cat get at pulling fur with another cat on a shed nights and you will hear grammar. A bluejay is human; he has got all a man’s faculties and a man’s weakness. He likes especially scandal; he knows when he is an ass as well as you do.
