Who lives in rookery?

A rookery is a breeding ground for certain animals, particularly seabirds like penguins, seals, and some species of herons and gulls. These locations are often characterized by large colonies where the animals gather to nest, raise their young, and socialize. In addition to birds, some marine mammals, such as sea lions, also use rookeries for breeding and resting. Overall, the term refers to a communal living space for these species during their reproductive seasons.
