Field Identification

12 cm; 12–16 g. Small, compact lark with rather stout bill; crouched feeding posture, recalling a canary (Serinus) or other finch. Has prominent whitish supercilium (often not reaching bill anteriorly, also sometimes interrupted by eye), dark eyestripe, dark moust­achial and malar stripes; small pale spot on forehead immediately above bill on some individuals; crown and upperparts brown, variably streaked darker brown; central tail brown, matching upperparts, rest of tail dark blackish-brown, outer feathers sometimes with narrow white edge; whitish below, regular blackish streaks on breast and flanks; eyes brown; bill mostly brown, paler yellow base; legs dull flesh-brown. Sexes alike. Juvenile undescribed.

Systematics History

Monotypic.

Subspecies

Monotypic.

Distribution

Coastal plain of C Somalia (50 km S of Jariban S to Halhambe).

Habitat

Vegetated coastal dunes, also open coastal plain with heavily grazed grass and scrub farther inland; extends up to 40 km inland in N, to only 1 km in S.

Movement

Unknown. Possibly resident, but often occurs in flocks of up to 30 birds, even during breeding season; may be subject to local movements within its small range.

Diet and Foraging

Diet unknown; probably consists largely of seeds. Feeds on the ground, in typical crouched posture; also creeps over low mats of vegetation, in manner atypical for a lark.

Sounds and Vocal Behavior

Flight call “tip-tip”; song unknown.

Breeding

May–Jul and Nov–Dec in years with sufficent rainfall. Nest an open cup, variably lined with vegetation, fluffy seeds and even pieces of woolly string, in shallow scrape in sand at base of a plant, often on S or E side (providing little shade), or partly concealed under thin cover of creeping vegetation; few nests found have been close to the sea (of six sites detailed, four were within 50 m of high-water line). Clutch 2–3 eggs (mean 2·2); no information on parental duties or incubation and fledging periods.

Not globally threatened. Currently considered Data Deficient. Restricted-range species: present in Central Somali Coast EBA. No recent information on the species’ status; was the most abundant passerine in coastal dunes in late 1970s with occasional flocks of up to 30 individuals (1). The most recent sighting was in Apr 2006, when several pairs were seen in Ceel Dheer and Mareeg (2) BirdLife International (2015) Species factsheet: Spizocorys obbiensis. Downloaded from http://www.birdlife.org on 26/10/2015. . Largely dependent on vegetated dunes; some concern that increasing grazing pressure, coupled with demand for firewood, will lead to destabilization of its dune habitat, especially around Mogadishu. As its range extends over minimum of 570 km from N to S, it is likely to be still secure in at least some areas. No population estimates. Nothing known about changes in population size. Available data are insufficient to support a robust assessment of its risk of extinction, and it is therefore classified as Data Deficient. Urgent need to carry out population census of sand dune habitat within known range, and obtain information on ecological requirements, threats and population trends.
