The Cactus Wren is a resident of the deserts of the southern United States and northern Mexico. At 7-8.75 in/18-22 cm long, it is the largest wren in North America. It is characterized by its white eye stripe, brown cap as well as a long, curved bill which is uses to probe for food on the ground or in branches. It eats insects and spiders as well as some fruit and nectar.

The Cactus Wren often builds its doomed nest between the arms of a cactus where the eggs and young are protected from predators. It is the state bird of Arizona.
