Rookery

What Is a Rookery?

A rookery is a special place where birds and some other animals gather to build nests and care for their babies. The word comes from rooks, a kind of bird that belongs to the crow family. Rooks like to build many nests close together in tall trees, making a lively and busy spot.

Animals That Use Rookeries

Many animals besides rooks use rookeries. Corvids, which include crows and ravens, often gather in these places. Seabirds like puffins and guillemots also come together on cliffs or islands. Even true seals, sea lions, and some turtles sometimes form groups where they rest and play.

A Word From the Past

Long ago, people in London used the word rookery to describe crowded neighborhoods. This was because the busy nests of rooks reminded them of busy city streets. Scientists think that even very old flying reptiles called Pterodaustro may have lived in groups like rooks, showing that grouping together is something many creatures have done for a very long time.
