Northern Mockingbirds: Aggressive Defenders of Nest & Young
Besides being known for their vocal repertoire, Northern Mockingbirds are famous for pugnacious defense of their territory, nest, and young. Even more than most songbirds, Northern Mockingbirds aggressively stand guard over their nestlings as well as their young fledglings. Potential predators risk being mobbed and chased by nesting mockingbirds. While the female incubates, the male spends most of his time perched high on trees or rooftops, acting as a sentinel, and will chase away any animal (including humans) that approaches the nest. Northern Mockingbirds have also been known to join forces with other birds, including cardinals, thrashers and doves, to chase away potential nest predators.
