About These Birds
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.
Australian Little Bittern
The Australian Little Bittern is a small heron found in freshwater wetlands and reed beds across Australia and New Guinea. Weighing about 89.5g with a wingspan of 26.3cm, it is a cryptically streaked bird that clings vertically to reed stems to avoid detection. It feeds on small fish, frogs, and aquatic insects.
