Ash's Lark Mirafra ashi



Justification

Justification of Red List Category
This species has a very small range and is therefore classified as Endangered. It may be threatened by development and is assumed to have a very small, declining population.

Population justification
The population is estimated at 3,460-6920 (10-20 individs/km2 x 346km2 [20% EOO]), i.e. in the band 2,500-9,999 mature individuals. This equates to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals. The species is described as locally common, so use the median to upper quartile of ten estimates of seven Mirafra spp. in the BirdLife Population Density Spreadsheet.

Trend justification
The population is suspected to be in decline owing to the development of its coastal habitat, as well as the potential indirect effects of drought and over-hunting on the numbers of livestock and wild ungulates. The likely rate of decline has not been estimated.

Distribution and population

Mirafra ashi remains known from only one small area just north of Uarsciek (80 km north of Mogadishu) in south-eastern Somalia, between 2°00'N and 2°30'N, where it is locally common (Ash and Miskell 1998). It has not been reported from the coast to the south-west of this site, where there has been intensive ornithological fieldwork. It is possible that it may occur north along the coast at least to 3°N (increasing its range to c.3,000 km2) as this area is virtually unexplored ornithologically (Ash and Miskell 1998). Nine other species of lark occur in the area, and M. ashi could easily have been overlooked among Red-winged Larks M. hypermetra hypermetra and Somali Long-billed Larks M. somalica rochei.

Ecology

Little is known about this species, which is found on semi-arid (350 mm rainfall), open, grassy coastal plains with a few, small, scattered bushes (Ash and Miskell 1998). Like M. somalica, it often runs across open ground between grass tussocks before perching on top of them (Ash and Miskell 1998).

Threats

If its range is indeed restricted to this single locality, it may be seriously threatened by new coastal developments reported from the area (Ash and Miskell 1998). The ecological relationship of this species with grazing animals is unknown, but it has been suggested that reduced numbers of domestic stock due to drought and loss of wild ungulates due to over-hunting may adversely affect its habitat.

Conservation actions

Conservation Actions Underway
No conservation action or fieldwork relating to this species has been undertaken for many years, due to the political instability in the area.

Conservation Actions Proposed
Clarify its distribution and population size and trend (Ash and Miskell 1998). Study the species's ecology. Investigate the effects of grazing-levels to assess potential threats. Protect suitable habitat from development. Legislate to reduce the hunting of wild ungulates.

Identification

14 cm. Small lark. Greyish-brown upperparts with paler edging to mantle feathers. Buff underparts with brownish streaks, but paler on belly and vent. Slight crest, with buff eyebrow-stripe. Similar spp. Singing Lark M. cantillans and Pink-breasted Lark M. poecilosterna are less greyish and less marked on mantle. Former has thicker bill and latter has pinkish breast. Rufous-naped Lark M. africana and Red-winged Lark M. hypermetra are larger. Voice Undescribed.
