A sparrow is a small bird that is typically brown or grayish in color. There are many different species of sparrows throughout the world, with more than 35 species found in North America alone. Sparrows are often called "LBJs" or "little brown jobs" by birders because they can be difficult to identify. Some key characteristics of sparrows include:

• Bill: A sparrows bill is relatively short and thick with a conical shape, which is perfect for cracking the seeds that are these birds primary food source.
• Diet: Sparrows are principally granivorous seed eaters, though they also consume a fair amount of insects.
• Flight Pattern: Sparrows are fast, agile fliers that use a series of rapid wing beats followed by a brief glide with folded wings to create an undulating flight pattern.

Sparrows are social birds that often form flocks with other species of birds. They are also known for engaging in social activities such as dust or water bathing and "social singing," in which birds call together in bushes. Sparrows are common in urban areas and are often associated with human settlements. They have been kept as pets, used as a food item, and are sometimes considered a symbol of lust, sexual potency, commonness, and vulgarity.
