The house sparrow used to be very common, but as we all know, they are becoming less common now. Not as spectacular as many other spices, they are however, very entertaining, noisy and gregarious. Sparrows enjoy their squabbles, the collective swimming and sun-bathing.
To decide whether you have a male house sparrow or tree sparrow, the tree sparrow has a chestnut crown and a black mark on its cheek, whereas the house sparrow has a grey crown.
In holes, often in buildings but will take over other nests or build in creepers and hedgerows. Tree sparrows favor more rural locations.
