Red - Billed Queleas - Kruger National Park


Orpen, Tamboti tented camp, Talamati and the Maroela Caravan Park in the Kruger Park are compelling birding spots. The Red – billed quelea, in addition to many other species of birds often occur in this area, one of the reasons being that the nearby Timbavati River watercourse is a dependable food source. During midday these birds will rest in the shade and drink on average at least twice a day. Red – billed queleas nest mostly in Acacia trees which are prolific in this mixed thorn and Marula woodland habitat.

Talamati is a small bushveld camp in the mixed woodlands of the N’waswitsontso .The camp is on the edge of the N’waswitsontso wetlands, which ensures there is usually good all-year-round birding.

Considered an invasive species and also known as the red-billed weaver or red-billed dioch, the red-billed quelea is the world’s most abundant wild bird species, with an estimated adult breeding population of 1.5 billion pairs. Some estimates of the overall population have been as large as 10 billion. The entire population is found in sub-Saharan Africa and is generally absent from deeply forested regions and the southern reaches of South Africa.

Unsurprisingly, there are more Red-billed Queleas in Kruger than any other species, with an estimated 33.5 million birds moving seasonally in and around the Park. They account for over 50% of the avian biomass in Kruger, moving in flocks of up to a million birds that nest en masse in acacia trees with between 50 and 3 000 nests per tree.
Feeding habits

Watching Red-billed queleas feed is like watching the Mexican Wave at a football crowd. The birds descend in their thousands onto the ground, with the flock taking on a roller feeding movement in which the birds at the back continually hop over the ones in front to get to the food. The Red-billed quelea is mostly a seed-eater but does eat insects, including butterflies, ants, beetles and termites. After the chicks hatch, they are nourished for some days with caterpillars and protein-rich insects. After this time parents change to feeding the nestlings mainly seeds. The young birds fledge and become independent enough to leave their parents after approximately two weeks in the nest.
Red – Billed queleas as a food source

Quelea are the avian equivalent of the impala – everything feeds on them. Nesting colonies are a favourite target not only for raptors but a wide variety of birds such as the Marabou Stork, Cattle Egret, Green-backed Heron and most of the hornbills. Whole colonies of Red-billed queleas can be devastated by predator attacks on adults, nestlings and eggs. Research at four Red-billed quelea colonies in the Park showed predation rates of 13%, 14%, 35% and 60%, according to Roberts VII. Additionally, snakes, lizards and several types of mammals are regular predators and some human populations also eat red-billed queleas. During their breeding season the Hadza of Northern Tanzania quelea eat quelea chicks by the thousands.
Breeding habits

During the breeding stage, the adult male is distinguished by his more colourful plumage and red bill. Breeding plumage in male queleas is unusually variable: comprising a facial mask which ranges from black to white in colour, and breast and crown plumage which varies from yellowish to bright red. For the rest of the year both males and fledged non-breeding birds have plumage that resembles that of the adult female, which is overall a cryptic beige and cream coloration. The female’s bill is yellow during breeding, and red during the non-breeding season.

Red- billed queleas are monogamous at each breeding attempt, but also itinerant breeding in which individuals may nest at up to three different locations within a season, thus likely that serial polygamy occurs. Their breeding season is from December to April in South Africa.

Nest sites are placed approximately 2m above ground level and mostly in Acacia thorn trees.

They typically lay 3-5 eggs that are pale green or blueish in colour. Chicks hatch after 10-12 days and are fed by both the male and female adults. The chicks are fed by regurgitation – even when feeding on insects.
