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.
Dwarf Bittern
The Dwarf Bittern (Ixobrychus sturmii) is a small heron of the family Ardeidae endemic to sub-Saharan Africa. It is the smallest heron found regularly in Africa, measuring approximately 25–30 cm in total length — smaller even than the Least Bittern of the Americas. Adults are dark slate-gray above, including the crown, neck sides, and upperparts, while the underparts are pale buff to whitish with dark brown streaking along the center. The wings show a rufous wing patch visible in flight. …
