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

| 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. |
