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.
Bermuda Night Heron
The Bermuda Night Heron was an extinct night heron endemic to Bermuda, known only from subfossil remains recovered from cave deposits. It likely fed on crabs and marine invertebrates in the island's intertidal zones, as its name suggests. It became extinct following the arrival of European settlers and the introduction of predatory mammals.
