12 c, 12-14 g, wingspan 26-27 c. Smallest hirundine of west Palearctic with character and behaviour of Sand Martin, but rather more compact form. Both upperparts and underparts duller than Sand Martin, contrasting less and no chest-band. Sexes similar, no seasonal variation. Habitat. Low latitudes near southern limits of west Palearctic. Consequently tolerates much warmer climates, but exposed to oceanic influences in Moroccan breeding area which reaches up to Mediterranean climatic zone. No significant differences in habitat from Sand Martin. Food and Feeding. No much informatiopn known from west Palearctic, elsewhere, diet consists of small flying insects. Takes prey in flight, often over water, often breaks surface in dipping to catch low-flying insects. Breeding.
