House Sparrows are fairly bulky-looking birds, with stout heads and thick bills. Males are easily told by their black bibs, black ‘face-masks’ and chestnut-brown heads with grey crowns. They also have broad white wing-bars. Female and juvenile House Sparrows appear dusky brown with grey-white undersides and dirty-brown but streaked backs. They lack the black bib of the male, and have pale brown crowns and a buff line above the eye.
