The Spanish, or willow, sparrow is a rather large sparrow, 15–16 cm long and 22–36 g, slightly larger and heavier than the house sparrow with a slightly longer, stouter bill. The male is like the house sparrow in plumage but has underparts heavily streaked with black, a chestnut rather than grey crown and white rather than grey cheeks. It is found in the Mediterranean region and south-west and central Asia, in two subspecies with little visible difference between them in worn breeding plumage (Wikipedia, general species account).
Each pair lays three to eight eggs, which hatch in 12 days, and the chicks fledge at about 14 days. Little is known of the species' survival rate, and the maximum recorded age is 11 years. The male's call when displaying at its nest differs somewhat from the house sparrow's, and other calls are almost the same (Wikipedia, general species account).
