Egret proves elusive in world’s largest Ramsar site
A survey team from BirdLife Botswana and the Botswana Department of Wildlife and National Parks recently completed a one-year survey of the 55,000 km2 Okavango Delta, the world’s largest Ramsar site and principal home of the Slaty Egret Egretta vinaceigula.
Valuable data on the ecology of this Vulnerable species were collected, but one question remains unanswered: where are Slaty Egrets currently breeding?
The species usually nests in dense reedbeds and water fig islands, but the major historical breeding sites have been destroyed by hydrological changes and fire, and no new sites were discovered in 2005.
Continuing survey work hopes to answer this question.
By contrast, Slaty Egrets feed in shallow seasonal floodplains with short, emergent vegetation, a habitat that is widespread throughout the Delta and has increased through fire and high grazing pressure.
Birds spend most of the day foraging for small fish, frogs and aquatic invertebrates which they locate by sight, but despite the abundance of prey, they appear to have a low feeding success.

For the past several years, the Independence Day fishing competition at the end of September has been held in the Okavango Panhandle, coinciding with the peak breeding time for the Near Threatened African Skimmer. This species nests on exposed sandbanks along the Okavango River, and the presence of a large number of fishermen and their boats has had a negative impact on its breeding success: here.
Botswana’s Okavango Delta is one of Africa’s most scenic and unspoiled wilderness areas, however, it is losing its wildlife at an alarming rate: here.
