It preferably inhabits farmland interspersed with hedges and small copses, orchards, vegetable gardens and edges of woods. It is not territorial. It nests in cavities and likes to use nest boxes, where, if necessary, it ejects weaker species. The beak of the Eurasian Tree Sparrow is finer than that of the House Sparrow which is why it eats grains before they ripen, when they are still milky-white. It prefers small grass seeds and all kinds of wild herbs."}
