Roquero Litoral

Monticola imerina

Ave robusta de tamaño mediano parecida a un petirrojo. Los machos son gris pálido y naranja, mientras que las hembras son pardo-grisáceas. Endémica de Madagascar, se encuentra en bosques espinosos costeros y matorrales en el suroeste. Se posa de forma conspicua. Su canto es una mezcla variable de silbidos finos y notas ásperas. Más pálida que el Zorzal Rocoso Forestal, con poca o ninguna superposición en su área de distribución. La hembra es similar a la hembra de la Urraca-petirrojo de Madagascar, pero más pequeña y grisácea, sin mancha blanca en el ala.

Identificación

As with the other rock thrushes, the littoral rock thrush is sexually dimorphic; the male has much more colorful plumage than the female does. He is pale gray on the head, breast, mantle and wing coverts, with dull orange underparts, gray-brown wings and a dark brown tail.

Taxonomía

When Gustav Hartlaub first described the littoral rock thrush in 1860, he assigned it to the genus Cossypha, believing it to be a robin-chat. It is monotypic, with no distinctive subspecies in its small range.

Distribución y hábitat

Endemic to Madagascar, the littoral rock thrush is found only in the country's southern coastal region, from the Onilahy River to Lake Anony, just to the west of Tôlanaro (formerly Fort Dauphin). It prefers euphorbia bushes and low shrubs on sandy substrate or coral rag, and is found at elevations ranging from sea level to 200 m (660 ft).

Conservación

Although the littoral rock thrush has a restricted range, its population appears to be stable, and the IUCN lists it as a species of Least Concern. However, the scrub habitat which it prefers is among the most degraded in Madagascar, and its population centers are largely outside of protected areas. Threats included clearing of scrub for agriculture, logging for firewood, and the presence of roaming livestock.
