Habitat:

Small pond at Palomar Mountain ~ 5300 feet in elevation. "American Bullfrogs are found throughout most of California, but they are absent from dry deserts and high elevations in the Sierra Nevada Mountains. The species is native throughout most of the midwestern, eastern and southern USA, reaching north barely into Canada, and south just below the Rio Grande River in Texas, and west to New Mexico and Colorado" - California Herps

Notes:

"A loud low-pitched two-part drone or bellow, popularly described as "jug-o'rum." These calls are made during the day and at night. Bullfrogs also produce an alarm call, a fast squeak, which is usually made before the frog jumps into the water to escape from danger. A sharp encounter call is also made, and a loud open-mouthed screaming sound is made when a frog is under extreme stress." - California Herps
