The house sparrow is not a native bird to North America, but was instead brought over to the United States in 1851. Within 50 years, the house sparrow population spread throughout all of America. House sparrows are now commonly seen across all of North America with the exception of Alaska and northern Canada.
In the US, the Migratory Bird Treaty Act of 1918 protects all native birds but does not apply to the growing house sparrow population. This is because house sparrows are an introduced species in America and are considered a pest bird.
House sparrows can be found in a number of different areas including urban and rural settings. House sparrows are one of the most widely seen pest bird in Northern America and have lasting populations because of their genuine lack of fear of humans and their aggressive behaviors to protect their flock.| Back |
