Pacific Tree Frog: Pseudacris regilla

Pacific Tree Frogs are generally found anywhere where there is water in the San Dieguito River Park. They breed from November to July and the calls of choruses of males hoping to attract females can be quite deafening at night. These calls have served as a nighttime backdrop for many Hollywood movies and TV shows over the years, so are known the world over! In the daytime, the frogs hide under debris, in vegetation or in burrows in the ground. This is the most common native frog in Southern California. Introduced Bullfrogs are a threat to the much smaller (0.75 to 1 inch long) Pacific Tree Frogs.
