The Bosque wildlife refuge is in New Mexico 80 miles or so south of Albuquerque. It is one of the premier bird refuges in the world. Every year when the birds are migrating from roughly November to January, the refuge is flooded with hundreds of thousand of Sand Hill Cranes and Snow Geese. In smaller numbers herons and eagles and ducks and coyotes can also be seen.
If you have ever heard the thunder of 100,000 Sand Hill Cranes lifting off all at once at dawn, I guarantee you will never forget it.
