They can be found in temperate deciduous forests; forested mountainous locales, like foothills and conifer forests; open woodlands, including diminutive woodlots; riparian woodlands, in dry regions; pinyon woodlands; farmlands; floodplains; and even in urban locations.

5.) A group of hawks is called a cast, kettle, aerie, boil, or lease.
