What is an aasvogel?

Merrium Webster Dictionary gives the definition of aasvogel as:"plural -s, Africa: vulture"

Vulture is the name given to two groups of scavenging birds of prey: the New World vultures, including the Californian and Andean condors, and the Old World vultures, including the birds that are seen scavenging on carcasses of dead animals on African plains. Some traditional Old World vultures (including the bearded vulture) are not closely related to the others, which is why the vultures are to be subdivided into three taxa rather than two. New World vultures are found in North and South America; Old World vultures are found in Europe, Africa, and Asia, meaning that between the two groups, vultures are found on every continent except Australia and Antarctica.

A group of vultures is called a wake, committee, kettle, venue, or volt. The term kettle refers to vultures in flight, while committee refers to vultures resting in trees. Wake is reserved for a group of vultures that are feeding.
