Needs no real introduction. Found on every continent in the world. A bird that thrives around human habitation. Their non stop chirping and cheeping is known everywhere. Their diet consists of seeds, nuts, berries, buds, insects and scraps. The RSPB has recorded a 60% decline in the house sparrow in the UK. There are many theories why this is so but none are proven.
Sparrows produce 3 clutches a year. The female does most of the incubating. Both adults feed the young. The juveniles look like the adult female. During the winter they form large social groups. Scouts are sent out looking for food and when it is found the rest of the group follow.
