Look and Appearance
Small birds known as house sparrows are commonly observed in pairs in rural areas, towns, and cities. They are most commonly confused with the Eurasian Tree Sparrow (P. montanus) in the United Kingdom and the Old World. The United States Midwest is home to a small portion of that species’ territory as well.
How do House Sparrows appear?
What does a sparrow look like? House Sparrows are easily distinguished from one another thanks to their strikingly varied colors and patterns. Male adults have white cheeks and a black mask, throat, and bib. The rear of the head is rufous brown, while the crown is gray. Their backs and wings are patterned with rich, warm brown and black markings, while their underparts are grayish.
The female House Sparrow is a quite dull little bird with minimal characteristics that set it apart. They have pinkish legs and a pale brown bill. They are grayish below and tan above. The two most noticeable marks on them are a pale stripe running from the eye to the nape and a little pale wing bar.
It is challenging to mate with juveniles before their dark bib and chestnut wing feathers mature. Juveniles resemble adult females in appearance. In juvenile females, the throat is also grayish, but in males, it is pale.
