Ecosystem and habitat
These white-breasted woodswallow species have low forest dependence. These species normally occur in altitudes from 0 to 2000 meters.
The artificial ecosystems and habitats of these woodswallow species include agricultural fields, plantations, canals, rural gardens, urban parks and degraded tropical and subtropical forests.
The natural ecosystems of these white-breasted woodswallow species include tropical and subtropical moist lowland forests, tropical and subtropical moist montane forests, mangrove forests, dry grasslands, flooded grasslands, dry savanna, marshes and rivers.
Diet and feeding behavior
The diet of white-breasted woodswallow consists mainly of flying insects. Beetles, cicadas, crickets, grasshoppers, mantids, moths, airborne termites and ants and airborne spiders are their primary food.
These white-breasted woodswallow species are arboreal and forage usually above the canopy. They make aerial sorties from conspicuous perches and hawk flying insects. They also form flocks and follow the swarming insects and catch them on the wing.
Reproduction and breeding habits
The breeding season of the white-breasted woodswallow species is from March to May in Indonesia (Sumatra). The laying season in Philippines is during March and April. The breeding season is from April to June in Java (Indonesia).
These woodswallows are monogamous and are strongly territorial. The breeding pair build a loose, shallow cup-shaped nest on the bare fork of a tree branch or in a hollow of a broken branch.
The woodswallow nest is a shallow saucer of interwoven moss, cobwebs, fibres, rootlets and pieces of bark. The typical clutch contains three pale green eggs with brown spotting. Both the parents take turns to incubate the eggs.
The white-breasted woodswallow parents feed the young with worms and insects. The nestlings are entirely altricial, being naked and blind, requiring continuous parental care.
Migration and movement patterns
These white-breasted woodswallow species are non-migratory resident birds. They make local nomadic movements. North to south movements have been observed in Australia.
Post breeding, the juvenile white-breasted woodswallows may disperse and establish in new locations within the range. They may make local movements for feeding and breeding within their range.
Conservation and survival
The global population size of the white-breasted woodswallow (
Artamus leucoryn) has not been quantified. The overall population trend of these species is reported to be stable.
Throughout its range this woodswallow species is reported to be common. The generation length is 5 years. Its distribution size is about 30,000,000 sq.km.
Degradation and fragmentation of habitats are the main threats that may endanger the survival of these woodswallow species.
IUCN and CITES status
The white-breasted woodswallow (
Artamus leucoryn) does not approach the thresholds for being Vulnerable under the range size criterion or under the population trend criterion, or under the population size criterion.
The IUCN (International Union for Conservation of Nature) has categorized and evaluated the species and has listed it as of "Least Concern".
The CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) status is ‘Not Evaluated’ for white-breasted woodswallow (
Artamus leucoryn).
