The Tablas fantail (Rhipidura sauli) is a fantail endemic to the Philippines on Tablas Island. Until recently, it was considered conspecific with the blue-headed fantail and Visayan fantail. It is threatened by habitat loss.
Description and taxonomy
[edit]EBird describes the bird as "A medium-sized, long-tailed bird of lowland forest on Tablas. Dull blue on the head, chest, back, and shoulder with some paler blue streaking on the chest and crown. Has a buff belly, a rufous lower back, rump, outer tail feathers, and wing, and a dark wing edge and dark central tail feathers. Tail often held cocked and fanned while foraging. Similar to black-naped monarch, but Tablas fantail has a rufous rump and tail. Voice includes single nasal 'jep' notes given at intervals or speeded up into a rapid series."[2]
It was formerly conspecific with the blue-headed fantail and Visayan fantail but it is differentiated from the with its darker brown belly, longer wings, lower pitched calls, stronger rufous wingpanel connecting to its back. [3]
This species is monotypic and has no subspecies.
Ecology and behavior
[edit]The diet of the Tablas fantail consists of insects. It is often observed in mixed flocks with other birds such as Rufous paradise flycatcher, Black-naped monarch, White-vented whistler and other small forest birds.
Barely anything is known about this species breeding behaviour. Young birds seen in late March. Breeding habits pressumed to be similar to the Blue-headed fantail which nests in a small cup made of plant fibers, roots and moss and lays 2 cream colored eggs with gray spots and blotches.[4]
Habitat and conservation status
[edit]The species inhabits tropical moist lowland primary forest in areas with mature closed-canopy forest. It is believed to be less tolerant to habitat disturbances compared to close relatives the Blue-headed fantail and Visayan fantail.[3]
The IUCN Red List classifies this bird as vulnerable with population estimates of 2,500 to 9,999 mature individuals. This species' main threat is habitat loss with wholesale clearance of forest habitats as a result of legal and illegal logging, and conversion into farmlands through Slash-and-burn and other methods.The species does not occur at high density even within the little remaining forest cover on Tablas:
Mt Palaupau serves as a watershed for Tablas Island.
There are no species specific conservation programs going on at the moment but conservation actions proposed include more species surveys to better understand habitat and population. initiate education and awareness campaigns to raise the species's profile and instill pride in locals. Lobby for protection of remaining forest and assess feasibility of reforestation projects,[5]
