winter, as flocks have been found in winter further south and east than where they breed, including in the United Arab Emirates and Saudi Arabia. Genetic analysis of birds in Israel revealed high connectivity among different populations indicating migration of individuals between these populations. However, despite this gene flow there is latitudinal variation in wing length and body mass, with individuals in the north of Israel having longer wings and being heavier than those in the south suggesting local adaption in accordance with Bergmann's rule. Behaviour This species feeds principally on seeds, like other sparrows. It breeds in dry lowlands with some shrubs, including tamarisk, and access to water. It builds a nest in a tree, and four to seven eggs are laid.
