Wetland wildlife is most abundant in winter, when snowbirds such as cinnamon teal and northern pintail use the refuge. During the summer months, look for permanent residents such as great egrets and muskrat.
In the desert, wildlife such as black-tailed jackrabbits and western whiptail lizards are plentiful. Watch at dawn and dusk for desert bighorn sheep and mule deer heading to the river for a drink.
Volunteer opportunities are available for individuals interested in assisting with the following programs: biology, environmental education, visitor center, and maintenance. Trailer pad hook-ups are available for volunteers with self-contained RV units. In addition, Student Conservation Association positions and internships may be available.
