As part of the Arizona Game & Fish Commission's "Arizona Wildlife Awareness" program in 1985, thousands of school children from around the state voted for an official state mammal, reptile, fish and amphibian. The winners would be introduced to the Arizona state legislature for approval as official representatives of the state.

Students studied 800 species in an effort to determine the best choice in each of the four categories. Four finalists were chosen for each category. In the amphibian category, the choice was limited to the red spotted toad, the Colorado River toad, the spadefoot toad and the Arizona treefrog.

When the votes were counted, it was clear that the students preferred the Arizona treefrog by a wide margin.

  1. The Arizona Treefrog (11,622 votes)
  2. The Colorado River toad (8,520 votes)
  3. The red spotted toad (6,346 votes)
  4. The spadefoot toad (3,486 votes)

Legislation was introduced in the Arizona State Legislature by Representative Larry Hawke and, on August 13, 1986, the Arizona treefrog became the official state amphibian of Arizona.

About the Arizona treefrog

The Arizona (mountain) treefrog is one of only two kinds, or species, of tree frogs found in Arizona. (The other species is the canyon treefrog, Hyla arenicolor.) If you don't have good eyes, you'll have a tough time spotting an Arizona treefrog. They're only about 3/4" to 2" long.

The little fellow in the picture is green, but they can be gold to bronze as well. They have a distinct black stripe that runs from their nose, through their eye and ends before their rear legs. Though whitish on their undersides, the male frog has a tan or greenish throat.

Arizona treefrogs have small pads at the ends of their toes. These pads are very useful when climbing in trees. In the early rainy season, male frogs can be heard calling from the high tree-tops. Their call has been described as a "nasal clacking sound with one to fifteen or more notes often given in succession."

When you go looking for Arizona treefrogs, look in oak, pine and fir forests higher than 5,000 feet above sea level. You'll find them in the mountains of central Arizona along the Mogollon Rim or in the Huachuca Mountains in Cochise County. That's where they live, eating insects.
