The house sparrow is a small bird typically of approximately 16cms in length. Females and young birds are coloured pale brown and grey, and males have brighter black, white, and brown markings.
Spreading quickly due to its lack of natural enemies and adaptive traits, the house sparrow has an ability to nest in urban structures, eat urban scraps and a large breeding capacity are some of these adaptive traits. Their legs and toes are favoured for branch perching and their short conical bills are ideal for seed cracking. Their diet consists of seeds and grains, as well as fruits, vegetables, human table scraps and insects. They are boisterous, intelligent birds that roost in noisy flocks on branches of trees and under eaves of houses.
