Identification
28 cm. A small, pale grey pigeon. Adult overall very pale grey with warmer upperparts and a dark tip to tail and dark band across rump. The crown is pinkish brown and the eye pale yellow. Oily green and blue iridescent patches on sides of neck apparent only at close range. Similar spp. Within its range might be confused with Feral Pigeon which is larger and much darker. Voice Typical pigeon-like cooings. Hints Little known pigeon but most likely seen at Guban Cliffs and in mountains east of Ras Asayr in N Somalia.

Distribution and population
Columba oliviae is a locally common species endemic to north-east Somalia (Ash and Miskell 1998). It has been found from 45°E east to Cap Guardafui and south down the east coast as far as 7°30'N (Ash and Miskell 1998). There have been records as recently as 2005 at a few sites, including in areas around Galgalo (J. Miskell in litt. 2006). Given its small range and the paucity of recent information, its status remains uncertain, though there is no evidence to suggest that it has changed in the last 60 years (J. S. Ash in litt. 1999). There has been no survey or conservation work carried out in recent years; something that is urgently required to improve existing knowledge of this species's abundance, distribution, ecology and possible threats.

Population justification
The global population size has not been quantified, but the species is described as probably rare, although poorly known (Gibbs et al. 2001).

Trend justification
The population is suspected to be stable in the absence of evidence for any declines or substantial threats.

Ecology
It is a ground-feeding, rock-dwelling bird of arid, coastal regions, at altitudes of 75-750 m (though once seen at 1,425 m), within 24 km of the coast (Ash and Miskell 1998). It is generally resident but shows seasonal movements locally (Ash and Miskell 1998). It feeds mainly on the ground, on seeds, cultivated grains and berries (Baptista et al. 1997). Very little is known of its breeding ecology (Baptista et al. 1997, Ash and Miskell 1998).

Threats
A potential threat may come from Speckled Pigeon Columba guinea, which is still expanding its range very rapidly in Somalia and was seen for the first time in the Galgalo area in April 2005 (Miskell in litt. 2006). How this may affect the Somali Pigeon remains to be seen. No other threats are known.

Conservation Actions Underway
None is known. Conservation Actions Proposed
Survey and monitor populations in suitable habitat within known range. Study breeding ecology and possible threats (including that posed by C. guinea).
