While nesting and raising their young, both types of sparrow feed exclusively on insects, especially arthropods (insects with segmented legs). Therefore, their traditional role in keeping down pests and maintaining the balance of nature is a very important one, though not always recognised. Recently the numbers of both species have declined substantially and in some areas they are now rarely seen. Long term studies have confirmed this drastic reduction in their numbers across Europe. The survival of these species is particularly threatened by widespread building renovation and clearance which denies them many nesting possibilities.
