A bird nest is the spot in which a bird lays and incubates its eggs and raises its young. Although the term popularly refers to a specific structure made by the bird itself—such as the grassy cup nest .. A blackbird will land on the base of the nest and lay the next strand of grass or twig on the top. She will then turn in the nest and carefully weave this new strand into the side of the cup. It's the turning action that leaves the inside of the nest completely smooth and well compacted, ready to take eggs and chicks.... Though most birds nest individually, some species—including seabirds, penguins, flamingos, many herons, gulls, terns, weaver, some corvids and some sparrows—gather together in sizeable colonies. Birds that nest colonially may benefit from increased protection against predation...
