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. …

The Ascension Night-heron was a flightless heron known from subfossil remains on Ascension Island in the South Atlantic. Weighing an estimated 624g, it was likely driven to extinction by human activity and introduced predators. It is currently listed as Not Evaluated by conservation assessments.
