You might hear humming birds, fly catches, mocking birds, grackles, dogs, children and traffic and airplanes. This stream is coming from my back garden in Tempe, Arizona. Arizona is part of the Sonoran Desert, and experiences a wide range of weather conditions from extreme heat in the summer through to monsoon, and even frost in the winter. It is a rich ecosystem with a wide range of birds, insects and other animals. This is an open back garden so you will also hear quite a lot of road traffic and as it is relatively close to the airport, quite a lot of plane traffic as well.
