The black-bibbed cicadabird is thought to be restricted to tropical moist lowland forest. It is threatened by habitat loss.
Description
editEBird describes the bird as "A medium-sized bird of lowland and foothill forest. Gray on the crown and back, with black feathers in the edge of the wing and a black tail with white corners. Male has a black forehead, face, and chest, and female has gray underparts. Races differ, with southern birds having paler bellies. Female is similar to female Blackish cuckooshrike, but Black-bibbed has a stouter bill and a paler belly. Voice includes a sharp "wek!" and a downslurred whistle repeated at short intervals."[2] It is often seen either alone or in mixed-species flocks,
They are sexually dimorphic in which males have the eponymous black bib and overall darker plumage with the females lighter and having "bibs" of either gray or white depending on the subspecies.[3]
Subspecies
editFive subspecies are recognized:
- Edolisoma mindanense mindanense: Found on Mindanao and Basilan
- Edolisoma mindanense lecroyae: Found on Luzon
- Edolisoma mindanense ripleyi: Found on Samar, Leyte, Bohol and Biliran
- Edolisoma mindanense elusum: Found on Mindoro
- Edolisoma mindanense everetti: Found on Jolo, Tawi-Tawi, and the island in the Sulu Archipelago[3]
Subspecies appear to fall into two plumage sets, mindanense and ripleyi are pale gray on males and pale grey to whitish on belly and rump on the females, Subspecies lecroyae, elusum and everetti are much darker gray in males and slaty gray on females. These considerable differences in plummage may one day lead these birds to be split but will need further study. [4]
Habitat and conservation status
editIts natural habitats at tropical moist lowland primary forest and secondary forest up to 1,000 meters above sea level.
The IUCN Red List has assessed this bird as vulnerable with the population being estimated at 2,500 to 9,999 mature individuals. Extensive lowland deforestation on all islands in its range is the main threat. Most remaining lowland forest that is not afforded protection leaving it vulnerable to both legal and Illegal logging, conversion into farmlands through Slash-and-burn and mining. Its preference for low altitudes suggests that it must have suffered population losses with the loss of lowland forest in the Philippines.
Conservation actions proposed are further surveys to better understand distribution and population status in remaining habitat. It is also recommended that protection in existing protected areas be improved and other key habitats be formally protectef.[5]
