These smart, curious birds seem to have a complex language when you listen to them, which I do most days, and they really understand human behavior well. They understand canine behavior even better, and constantly play tag games with Tillie.
Ravens IQ -- this is an excerpt from the great PBS episode on Ravens, who have the largest brain size relative to their weight of any bird, live about 40 years, and mate for life.
They can be very destructive--damaging window screens, hot tub covers, and anything else they are curious about--this box below was investigated between dawn and 7 a.m. this morning, ans they poked numerous holes and yanked out bits of a large plastic bag covering my new Thule storage pod.
They are over-populated here, due to the ready availability of compost piles for foraging, indicates the Dept. of Fish and Game.
