Range and Habitat
Common Waxbill: Breeds in open, grassy areas in Sub-Saharan Africa. Several populations have also become established in other parts of the world including Hawaii. First reported on the island of Oahu in the late 1970s, it has spread to other islands. Most populations are resident although some make local movements in search of seeding grasses.
Breeding and Nesting
Common Waxbill: These finches are monogamous. Four to seven eggs are placed in a round nest made of grass and with an entrance tube at the bottom. The nest is placed in a cavity in low, dense vegetation. The eggs are incubated by both sexes for 11 to 13 days. Fledging takes 17 to 21 days, and during this time both parents feed and care for the chicks.
Foraging and Feeding
Common Waxbill: These waxbills are granivores, feeding on seeds from pasture grasses and millets, fruit flies and small worms. They forage in flocks of two to twenty during the day, feeding mostly in the early morning and late afternoon. They either perch on the panicle while plucking seeds or pull the panicle to the ground. Seed removal is done with the bill in both cases.
Vocalization
Common Waxbill: Short song of two dry notes followed by two longer, nasal notes. Contact call is a sharp "jip." Contact call song is two to three sharp notes, followed by a bubbling sound, "ti-cket please!" or "di-di-di-JEEE".
