Red-billed quelea in colour, sometimes with some dark spots. Some clutches contain six eggs, but large clutches may be the result of other females dumping an egg in a stranger's nest. Both sexes share the incubation of the eggs during the day, but the female alone does so during the cool night, and feeds during the day when air temperatures are high enough to sustain the development of the embryo. The breeding cycle of the red-billed quelea is one of the shortest known in any bird. Incubation takes nine or ten days. After the chicks hatch, they are fed for some days
Red-billed quelea "aethiopica". Linnaeus himself did not explain the name "quelea". "Quelea quelea" is locally called "kwelea domo-jekundu" in Swahili, "enzunge" in Kwangali, "chimokoto" in Shona, "inyonyane" in Siswati, "thaha" in Sesotho and "ndzheyana" in the Tsonga language. M.W. Jeffreys suggested that the term came from medieval Latin "qualea", meaning "quail", linking the prodigious numbers of queleas to the hordes of quail that fed the Israelites during the Exodus from Egypt. The subspecies "lathamii" is probably named in honor of the ornithologist John Latham. The name of the subspecies "aethiopica" refers to Ethiopia, and its type was collected in the neighbouring Sennar
