The range and numbers of this bird are decreasing, probably due to habitat loss.
Texas is the second largest U.S. state by both area and population, and the largest state by area in the contiguous United States.The name, based on the Caddo word "Tejas" meaning "friends" or "allies", was applied by the Spanish to the Caddo themselves and to the region of their settlement in...
population was solely known from a 105 acre (0.4249203 km²) brushfield near Houston and disappeared after devegetation due to industrial development in the 1980s. It was considered a distinct subspecies (A. h. houstonensis
: Arnold, 1983) but is today considered to fall into the range of variation of the nominate subspecies (Browning, 1990). Likewise, the South Dakota
South Dakota is a state located in the Midwestern region of the United States. It is named after the Lakota and Dakota Sioux American Indian tribes. Once a part of Dakota Territory, South Dakota became a state on November 2, 1889. The state has an area of and an estimated population of just over...
