What are the benefits of being a rookery?

A rookery is a communal nesting ground for gregarious birds consisting of anywhere from just a few nests to hundreds of nesting pairs in a relatively small area.

Now, we know what one is the benefits are a safe place for parent birds who are aggressive toward other adults or young birds that invade the personal space of their nest, and they give shelter for birds with scares nesting areas...those are a few benefits but if you still need more info just comment and I'd be happy to help :)
