Red-billed quelea A sociable bird, the red-billed quelea tolerates mixed-species aviaries. Keeping many individuals mimics its natural occurrence in large flocks. This species withstands frosts, but requires shelter from rain and wind. Affixing hanging branches, such as hawthorn, in the cage facilitates nesting. Adults are typically given a diet of tropical seeds enriched with grass seeds, augmented by living insects such as mealworms, spiders, or boiled shredded egg during the breeding season. Fine stone grit and calcium sources, such as shell grit and cuttlebone, provide nutrients as well. If provided with material like fresh grass or coconut fibre they can be bred.
Red-billed quelea during daylight hours. The governments of Botswana, Ethiopia, Kenya, South Africa, Sudan, Tanzania, and Zimbabwe have regularly made attempts to lessen quelea populations. The most common method to kill members of problematic flocks was by spraying the organophosphate avicide fenthion from the air on breeding colonies and roosts. In Botswana and Zimbabwe, spraying was also executed from ground vehicles and manually. Kenya and South Africa regularly used fire-bombs. Attempts during the 1950s and '60s to eradicate populations, at least regionally, failed. Consequently, management is at present directed at removing those congregations that are likely to attack vulnerable fields. Red-billed quelea
