These bats are found from southern Canada into Central America. They often roost in barns and under bridges, and move into caves and mines to hibernate. Apparently, some individuals use the same feeding ground on different nights. After feeding, they fly to a night roost to rest.

Big brown bats are not listed as endangered because they are widely distributed throughout their range and populations appear to be relatively stable.

crested saguaro

Tonto National Monument is home to a crested saguaro. Botanists disagree as to why some saguaros grow in this unusual form. Some speculate that it is a genetic mutation. Others say it is the result of lightning or freeze damage. About one in 150,000 saguaros develop this unusual growth.
