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.

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. …
