Habitat and Ecology [top]
Habitat and Ecology:
Behaviour The species is widespread (within 15?N to 31?S), with an afro-Malagasy, Indomalayan and fringing north Australasian distribution (Ferguson- Lees and Christie, 2001), but this is fragmented and the species is locally uncommon. Within sub-Saharan Africa, the species is distributed from Senegal, east to Kenya, including central Ethiopia, and as far south as the northern boundary of Namibia and Zimbabwe. Within Southeast Asia, it is found in peninsular Thailand, south Tenasserim, Malaysia, Sumatra, Borneo and southeast New Guinea. Its presence has also been established in Madagascar and north-central Sulawesi, but there are no breeding records for either (Ferguson- Lees and Christie, 2001). In general, the species is considered sedentary, but it may have some migratory movements suggested by its appearance in southwest Madagascar during the southern winter, and in unusual habitats in sub-tropical southern Africa and in northeast tropical Africa (del Hoyo et al., 1994; Ferguson- Lees and Christie, 2001).
The species is crepuscular, predominantly active in single short periods during dusk (Brown et al., 1982; Ferguson- Lees and Christie, 2001). It remains at roost on a perch during daylight, then becomes alert at sunset, preening for up to 30 minutes before foraging. Most prey are caught during a 20 minute period at dusk, but some hunting occurs at dawn or at night if bats are active near artificial light sources or in moonlight. The species will patrol areas near the entrance to bat roosts or water bodies, catching prey on the wing and swallowing it whole, although they will also occasionally still-hunt from a perch.
In West Africa, breeding occurs during March-June and October-January, in East Africa between April and August and in Southern Africa during September-December. For the Indomalayan range, breeding occurs during April-September.
Habitat The species occupies a range of habitats up to 2000m that include forest, disturbed forest, towns, and - less frequently - dry bush. The species’ presence is essentially determined by the occurrence of flying prey (particularly bats) that are active at dusk (Ferguson- Lees and Christie, 2001).
Diet The species’ diet is largely composed of small bats (20-75g), birds (including cave-nesting swiftlets in Malaysia and Indonesia, and various swifts, hirundines, nightjars and other groups in Africa), and large insects (Brown et al., 1982; del Hoyo et al., 1994; Ferguson- Lees and Christie, 2001).
Breeding Site Nest platforms are constructed in the upright forks or outer lateral branches of tall, leafy, emergent trees such as baobab or eucalyptus, and are composed of sticks lined with smaller twigs and occasionally also leaves. It is often faithful to the same site for many years (Brown, et al., 1982). The species has also been known to nest in town trees where bats are often present (Brown et al., 1982; del Hoyo et al., 1994; Ferguson- Lees and Christie, 2001).
Management Information The species may be declining in Borneo although its status is little known. It is not known to be affected by pesticides, even though their bat prey probably are (del Hoyo et al., 1994).
