Rooibekkwelea [Afrikaans] – (Quelea quelea)
Oh my! The
Red-billed Queleas have moved into my garden (Tarlton, Gauteng, South
Africa)! When I feed in the mornings, they descend on the feeding tables
by the dozens! They are very wary and skittish and the slightest
movement will send them fleeing, taking off like one body and returning
as one in waves of motion, absolutely fascinating to watch. But the rest
of the garden birds have a problem getting to the food and every day
there seems to be more and more of the Queleas.
At the moment
the males are in their full breeding plumage, with their bright red
bills and black face. The juvenile males stand out amongst the other
birds like a beacon with their pre-adult little cream caps. Within 2-3
months of hatching, juvenile birds complete a post-juvenile moult to
resemble non-breeding adults, but with cream head, whitish cheeks and
buff edges to flight feathers and wing coverts, followed 1-2 months
later by a pre-nuptial contour moult, when they begin to assume the
adult breeding plumages.
Queleas are the most abundant wild
birds on the planet, with an estimated population of 1.5 billion birds,
occurring across much of sub-Saharan Africa, excluding the lowland
forests of West Africa, arid areas of southern Namibia, south-western
Botswana and the southern half of South Africa. It is most prolific in
semi-arid habitats such as thorn-veld and cultivated land, but it may
also occupy exceptionally wet or dry areas. Not threatened, it is so
abundant and such a pest that millions of birds are culled annually
using explosives at roost sites and aerial spraying, but even that
doesn’t have any long term affect on its population.
