About These Birds
American Bittern
The American Bittern is a large heron weighing about 735 g with a 54.2 cm wingspan, inhabiting freshwater marshes and reed beds across North America. When threatened, it freezes with bill pointed skyward, its streaked brown plumage blending remarkably with marsh vegetation.
Black Heron
The Black Heron is a medium-sized, all-black heron famous for its unique canopy-feeding technique, in which it spreads its wings like an umbrella over the water to create shade and attract fish. It inhabits shallow freshwater lakes, marshes, and flooded grasslands across sub-Saharan Africa and Madagascar. It feeds primarily on small fish and aquatic invertebrates attracted to the shade created by its distinctive wing canopy.
