Egretta vinaceigula
The Slaty Egret (*Egretta vinaceigula*) is a medium-sized, highly distinctive, and critically vulnerable wading bird native to the wetlands of south-central Africa. Growing 43-60 cm (17-24 in) in length with a wingspan of 90-107 cm (35-42 in) and weighing 250-360 g, its plumage is entirely slaty-grey, often appearing purplish-brown in certain light conditions. Key identification marks include its striking bright yellow-green legs and feet, a dark bill with a yellowish base, and most notably, ...
This specialized egret primarily inhabits shallow freshwater wetlands, including floodplains, temporary pans, and dense emergent vegetation like papyrus and reeds. It is typically found in low-lying areas, generally below 1000 meters in elevation.
The Slaty Egret's diet primarily consists of small fish, amphibians (especially frogs), and aquatic invertebrates like insects and crustaceans. They are ambush predators that rely on their specialized 'canopy feeding' technique to capture prey.

Their foraging strategies are highly distinctive, employing 'canopy feeding' or 'umbrella feeding' where they spread their wings forward to create shade, reducin...
The Slaty Egret's distribution is restricted to a relatively small area of south-central Africa, making it a species of high conservation concern. Its core breeding and resident range includes Botswana, particularly the Okavango Delta, Linyanti Swamps, and Chobe River system, as well as northern ...
