Taxonomic Notes: Lewinia pectoralis and L. mirifica, cross-regional species, and L. muelleri, a New Zealand endemic (Sibley and Monroe 1990, 1993) are retained as separate species contra Turbott (1990) who include mirifica and muelleri as subspecies of L. pectoralis, pending revision of the New Zealand CheckList. Gender agreement of species name follows David and Gosselin (2002b).

This species is listed as Data Deficient because there are few recent records and almost nothing known of its distribution, population, ecology and threats, thus an assessment of its threat status is currently not possible.

Geographic Range [top]

Range Description: Lewinia mirificus is known from Luzon and Samar in the Philippines, to which it is probably endemic, although as breeding there has not been confirmed, this remains to be proven (Collar et al. 1999). The vast majority of records derive from the migration funnel, and bird-catching site, of Dalton Pass on Luzon, where over 200 were recorded between 1965 and 1970, suggesting that it may persist in reasonable numbers, and that it is migratory. In October 2009, 10 individuals were recorded as they were caught by bird-trappers (Allen 2010). Although breeding and non-breeding areas are uncertain, these records infer movements either between the Cagayan valley and Luzon's central plain, or between the Cordillera Central and the Sierra Madre mountains; if the former is true, the records from south Luzon and Samar may relate to overshooting migrants. Recently an individual was observed in degraded cloudforest at 2,240 m on Mount Data, Luzon in January 2001. The bird was heard to call (a frog-like accelerating series of clicking notes), and the same call was heard in cloudforest at 1,100 m on Mayon Volcano in Southern Luzon (Dinets 2001).

Habitat and Ecology [top]

Habitat and Ecology: Although it has been speculated that it has strict habitat requirements, if these are similar to its congener (and possibly conspecific) Lewin's Rail L. pectoralis, it may prove to be rather cosmopolitan in its preferences, as the few documented details (cloudforest, near pine forest, and in a small undisturbed riverside swamp), from 550-2,250 m, imply.

Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Unknown
Generation Length (years): 3.7
Movement patterns: Not a Migrant

Threats [top]

Major Threat(s): The only known threat is hunting (evidenced at Dalton Pass), although the impact of this on its population cannot currently be gauged.

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
None are known.

Conservation Actions Proposed
Prioritise fieldwork to clarify the distribution and habitat requirements of the species and to locate viable populations at sites where it might be effectively protected.
