I would have no doubt that a lot of the best places for birds to live in American desserts particularly those in Arizona have been taken over by People or their Human Development. If there was far fewer people living in Arizonan dessert climates, bird populations would not be so threatened by the heat. It is a well-known meteorological fact that the Arizonan dessert climate has been far drier and hotter in the relatively recent past. Climates there have fluctuated naturally rather dramatically over the decades or hundreds of years. Also dessert habitats are definitely the not the best place to stuff millions and millions of people as in the Phoenix mega-suburban sprawl area or the less one around Tucson.

For all of you that love to bird in desert areas.
