They also hold up an object to get another bird’s attention. A study in Austria found that ravens point with their beaks to indicate an object to another bird, just as we do with our fingers. In other words, they gesture to communicate. It turns out that ravens make “very sophisticated nonvocal signals,” according to researchers. And sometimes they just taunt or mock other creatures because it’s funny. Ravens even make toys-a rare animal behavior-by using sticks, pinecones, golf balls, or rocks to play with each other or by themselves. They often play keep-away with other animals like wolves, otters, and dogs. In Maine, they have been seen rolling down snowy hills.

Ravens have been known to imitate wolves or foxes to attract them to carcasses that the raven isn’t capable of breaking open. They also mimic other noises, like car engines, toilets flushing, and animal and birdcalls. In captivity, ravens can learn to talk better than some parrots. Since the other ravens are smart too, this only works sometimes. If a raven knows another raven is watching it hide its food, it will pretend to put the food in one place while really hiding it in another. In the wild, ravens have pushed rocks on people to keep them from climbing to their nests, stolen fish by pulling a fishermen’s line out of ice holes, and played dead beside a beaver carcass to scare other ravens away from a delicious feast. Many ravens got the food on the first try, some within 30 seconds. In one logic test, the raven had to get a hanging piece of food by pulling up a bit of the string, anchoring it with its claw, and repeating until the food was in reach. When it comes to intelligence, these birds rate up there with chimpanzees and dolphins. Many other calls also exist such as begging calls by females to their mate, by young to their parents, idle songbird chatter, and distress calls when seized by predators.

Changes in direction can be extremely quick, probably helped by the bird's long tail.
Non-flapping phases are often interspersed throughout the flight. Primaries, secondaries, tertials and rectrices are replaced sequentially, so the bird can still fly during molting. Molt begins earlier in males than in females, and in second-year birds than in older ones. They also belong to that group of birds that scratch their head with their foot over the wing. Like other corvids, black-billed magpies indulge in anting (applying ants onto their plumage) and sun-bathing (back facing the sun, head down, wings drooped and spread wide, tail fanned, back feathers fluffed up). Divorces are possible: one South Dakota study found low rates of divorce 8% but one 7-year study in Alberta found divorce rates up to 63%.
