Mountain Shrike Lanius validirostris

Justification
This species is restricted to various small patches of suitable habitat within a small range. It is therefore likely to have a small global population that is fragmented in structure; however, it is thought to be stable at present, thus the species is considered Near Threatened. It should be carefully monitored for any evidence of future population declines.

Taxonomic source(s)
Sibley, C. G.; Monroe, B. L. 1990. Distribution and taxonomy of birds of the world. Yale University Press, New Haven, USA.

Distribution and population
Lanius validirostris is endemic to the Philippines, where it occurs on Luzon (nominate validirostris, in Cordillera Central and Sierra Madre), Mindoro (race tertius) and Mindanao (race hachisuka, including on Mt Kitanglad, Civolig, Mt Malindang and Mt Apo) (Collar et al. 1999).

Population justification
The population size of this species has not been quantified, but it is described as uncommon.

Trend justification
Data are lacking on population trends, but habitats are thought to be secure at present, so the population is assumed to be stable.

Ecology
This species is found in clearings within forest in the highlands, above 1,000 m.

Threats
Although its area of occupancy must be small, its habitat is apparently secure and it is present in a high proportion of suitable patches.

Conservation Actions Underway
No targeted conservation actions are known for this species, although some of its habitat is protected.

Conservation Actions Proposed
Conduct repeated surveys in areas within and surrounding the species's range to determine its current distribution and abundance, as well as assess population trends and rates of habitat loss. Conduct ecological studies to improve understanding of its precise habitat requirements, tolerance of secondary habitats and response to fragmentation. Protect areas of habitat occupied by the species and safeguard against future threats.
