“…The range in incubation period recorded in this study fell within this range. Two of the three nestling periods measured were shorter than the 31 days reported by Prozesky (1966) but within the range of 27 to 30 days given by Maclean (1985).…”

“…It nests in holes in trees and both male and female incubate the eggs and provide food to the young. Apart from incidental observations on its plumage and distribution (Lewis 1982), vocalizations (Ward 1986) and reproductive behaviour (Prozesky 1966;Van Zyl & Greyling 1988), little is known about the biology of the Crested Barbet. The aims of this paper are twofold: first to provide information on the breeding biology of the Crested Barbet in a suburban environment, and second, to relate the variation in breeding success to annual and seasonal rainfall in comparison with other studies.…”

“…The Crested Barbet Trachyphonus vaillantii has a patchy distribution extending from Tanzania in the east to Angola in the west and South Africa in the south (Short & Horne 1988). It is a territorial monogamous species which lives in a variety of woodland habitats including gardens, and feeds primarily on insects and fruit.…”

VAN ZYL, A.J. 1994. The influence of the environment on the breeding success of a suburban population of Crested Barbets Trachyphonus vaillantii. Ostrich 65: 291-296. I studied the breeding biology of the Crested Barbet Trachyphonus vaillantii in Colbyn, a suburb east of Pretoria, South Africa, for nine breeding seasons from 1981 to 1989 to examine atterns in annual breeding success, breeding attempt success in multiple broods, and rainfall. The m o z l incubation period was 14 days and the nestling period ranged from 28 to 31 days. Average clutch size for all the years was 3,3 eggs/clutch and there was no significant difference in clutch size or number of young fledgednest between years. On average, Crested Barbet pairs made 2,4 breeding attempts/season. There was no difference in clutch size or breeding success between the breeding attempts. Crested Barbets nesting in natural nests laid on average larger clutches than those in artificial nestboxes, but had non-signficantly lower breeding success. Failure to raise Crested Barbet chicks was attributed to parasitism by Lesser Honeyguides Indicator minor, bee swarms occupying nestboxes, and flooding of natural nests. Breeding performance was not correlated with rainfall or adult body size. The suburban environment may be less variable than a natural environment, resulting in a stable breeding Crested Barbet population.
