Ecosystem and habitat

These silver-breasted broadbill species have moderate forest dependence. These species normally occur in altitudes from 300 to 2000 meters. The artificial ecosystems of these species include agricultural fields and rural gardens.

The natural ecosystems of these broadbill species include tropical and subtropical moist lowland forests, evergreen forests, tropical and subtropical moist montane forests, semi-evergreen forests, bamboo forests and deciduous forests.

Diet and feeding behavior

The diet of the silver-breasted broadbill consists mainly of insects. A variety of invertebrates like insects and their larvae, grasshoppers, mantises, caterpillars and small land snails are their primary food.

They hawk the flying insects from air and also glean the prey from the tree branches.

Reproduction and breeding habits

The breeding season of the silver-breasted broadbill species is from March to August. These birds are monogamous. The nest is hung from the tip of a tree branch with an average height of two meters above the ground.

The silver-breasted broadbill nest is a bulky untidy ball of twigs with a lateral entrance. Both the pair take part in nest construction. The clutch contains 3 to 5, glossy, white, oval shaped eggs. The eggs are laid with a interval of one day.

The silver-breasted broadbill chicks hatch out after 15 days. The hatchlings are strongly altricial and helpless, being blind and having naked body. Both the parents incubate the eggs and care for the young.

Migration and movement patterns

The silver-breasted broadbill species are non-migratory resident birds. Birds in higher elevations may move to lower levels and plains in winter.

Post breeding, the juvenile broadbills 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 silver-breasted broadbill (Serilophus lunatus) has not been quantified. The overall population trend of these species is reported to be decreasing.

Throughout its range this broadbill species is reported to be locally common to uncommon. The generation length is 4.2 years. Its distribution size is about 4,060,000

Deforestation, habitat degradation and fragmentation and capture of adults and juveniles for pet trade are the main threats that may endanger the survival of these broadbill species.

IUCN and CITES status

The silver-breasted broadbill (Serilophus lunatus) does not approach the thresholds for being Vulnerable, either 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 broadbill 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 silver-breasted broadbill (Serilophus lunatus).
