Pacific Chorus Frog

Pseudacris regilla

Also known as Pacific Tree Frog, Northern Pacific Tree Frog

Pacific chorus frogs are famous for producing the iconic double-syllable ribbit call featured in countless film soundtracks. Capable of shifting their skin color from bright green to dark bronze within hours, individuals are instantly recognizable by a dark eye mask running from snout to shoulder. These versatile amphibians thrive from coastal wetlands up to alpine meadows, gathering in deafening breeding choruses around quiet ponds each spring.

Responsible observation
  • Listen at Dusk: Locate breeding males near quiet ponds by following their loud ribbit calls during spring nights.
  • Look for the Mask: Identify individuals by the distinct dark stripe running from the snout through the eye.
  • Protect Sensitive Skin: Avoid handling with dry or unwashed hands to prevent transferring oils or chemicals.
