South Africa: Researchers Ring City Hadedas in Search for Secrets of Their Success

March 30, 2007

Talk about an exclusive fashion statement! About 32 youngsters are strutting their stuff in Cape Town, sporting exclusive jewellery – rings that are all the rage.

Exclusive and a fashion statement if you’re a bird, that is, and in particular if you’re a young Hadeda Ibis.

This large, raucous, and unmistakable species is a relative newcomer to Cape Town.

The birds are naturally most common in the Eastern Cape and KwaZulu-Natal and were first recorded in the Western Cape in the early 1980s, but by the end of the decade had established themselves firmly in the city.

Researchers Res Altwegg and Doug Harebottle, at the University of Cape Town’s Avian Demography Unit, have been trying to understand this migration and last year appealed to human residents to help them find the Hadedas’ nests.

Harebottle said the Hadedas, whose loud “Ha-ha-hah” or “ha-de-dah” reverberates through the suburbs – usually at first light as they leave their night roosts – normally breed from late July to November.

Large trees, such as pines, are often used as nest sites, although these birds also use small trees or bushes on islands in wetlands, and they are also known to nest in suburban gardens that have suitable trees.

“Hadeda numbers have been on the increase in the Cape Town Metropole since their arrival 20 years ago. But why have they become such a successful species here and in perhaps many other cities in South Africa?” said Harebottle.
