Scientific Name: Lalage sharpei
Species Authority: Rothschild, 1900
Common Name(s):
English Samoan Triller

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01
Assessor(s): BirdLife International
Reviewer(s): Butchart, S. & Symes, A.
Facilitator/Compiler(s): Derhé, M., Mahood, S., O'Brien, A., Shutes, S.
Justification:
This species qualifies as Near Threatened because it is likely to have a moderately small population and range which is declining as a result of habitat degradation. Further data on population size and trends for this species are urgently required and may lead to it being uplisted to Vulnerable.

Geographic Range [top]

Range Description: Lalage sharpei is endemic to Samoa where it is found on Savai'i (race tenebrosa) and Upolu (nominate sharpei). In a survey during 1984, it was nowhere common in the O le Pupu-pu'e National Park on `Upolu (Beichle and Maelzer 1985), and it is regarded as uncommon overall. There are no published population estimates.

Population [top]

Population: The global population size has not been quantified, but the species is described as generally uncommon (del Hoyo et al. 2005).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It inhabits primary and secondary forest and forest edge above 600 m on Savai'i (race tenebrosa) and at least to 200 m on `Upolu (nominate sharpei). It also occurs (rarely) in cattle pastures where there is undergrowth and trees, and in traditional plantations with few permanent houses (Beichle in prep.). It feeds on fruits and invertebrates (Beichle in prep.).

Systems: Terrestrial

Threats [top]

Major Threat(s): Pupu-pu'e National Park on `Upolu, which is unmanaged, was severely damaged by cyclones and is threatened by logging and cattle farming (Beichle and Maelzer 1985, Bellingham and Davis 1988, Elmqvist et al. 1994). These threats are likely to be operating throughout its range. It is likely to be a sedentary species and requires the protection of primary forest to secure its survival(Beichle in prep.).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
The species occurs in Pupe-pu'e National Park.

Conservation Actions Proposed
Investigate population size to establish a baseline against which trends can be assessed. Manage and protect Pupu-pu'e National Park. Conduct a community education programme to promote animal husbandry practices which have minimal impact on the forest.
