COOL FACT

TOP
Birds in the Family Corvidae (called "corvids") are among the smartest birds known (probably second to birds in the parrot family). Magpies can find objects that have been moved from one hiding place to another, even when they didn't witness the objects being moved. Clark's Nutcrackers (pictured left) can remember a thousand different locations where food has been hidden. Some corvids are thought to be able to recognize all of the individuals in their family group.

COOL FACTS about Family Corvidae

TOP
Pinyon Jays live in flocks that move around together in a large area called a home range. They mate for life and the pairs build their nests inside the home range. Most of the pairs in a flock nest at the same time. Pinyon Jays that nest too close together steal nesting material from each other, sometimes causing nests to fail. Some one-year-old males that do not nest, help their parents feed their new nestlings. Nests with "helpers" often produced more young than nests without helpers.
