Pacific Chorus Frogs in the Willamette Valley

The Pacific Chorus Frog (Pseudacris regilla, also known as the Pacific Tree Frog) is very common in the Willamette Valley, Oregon and elsewhere in western North America. In late winter and spring, loud choruses of hundreds or thousands of frogs can be heard. These tiny frogs mate and lay eggs in lakes, ponds, slow-moving streams, shallow bodies of water, flooded fields, ditches and more. Learn about what they look like, what they sound like and how you can watch them making their “ribbit” call.

Great look into the world of these froggy choristers, thanks.

Thank you for all the wonderful info!

Love the frogs, I got a bio terrarium for my Regilla.
They do have quite the royal demeanor about them.
I hope they can enter the pet trade as they are amazing.

I have a few frogs that have paderns of both brown and green on them.

​@@riomio7852 I see those in my plant pots and in my yard. I'm in Eugene Oregon

These chorus frogs sound like the frogs in Mill Creek in The Dalles.

Yep, those would be Pacific Chorus Frogs. They are the main frog you hear in the Pacific Northwest, including The Dalles.

Great video! How late in spring are the chorus frogs likely to be breeding? I ask because I finally caught and destroyed a female bullfrog that had taken up residence in my backyard pond, and I wonder if the surviving chorus frogs still have time to breed this year.

[@neighborhood-naturalist]

Pacific Chorus Frogs may have multiple clutches in a season. They may continue to lay eggs until the summer heat gets too intense. There are a lot of local factors involved, like available food, water temperatures and predator pressure. Are there any more bullfrogs, including tadpoles?

[@signedanler6188]

@@neighborhood-naturalistNot that I've spotted. One usually moves in to our pond. If it is a male, we hear it of course, and catch it as quickly as we can. So far we've gotten them before any breeding occurs. For the last couple of years it has been this female, who has been growing and hasn't gone off to find a male. I finally caught her with a flashlight and net. I'm very glad to hear the chorus frogs have time, and I'll be watching for any bullfrog tadpoles just in case.
