Mockingbirds are "famous for their loud, continuous, and varied songs. A male Northern mockingbird may learn up to 200 different songs in its lifetime, incorporating diverse sounds it hears in its environment. Unmated males often sing throughout the night during the breeding season. They are known for being fiercely territorial, aggressively defending their nests and young by chasing away intruders, including much larger animals and even humans. They also perform a 'wing flash' display, where they half-open their wings in jerky steps while on the ground, which may help startle insects into moving." MORE PHOTOS
