๐ŸธChorus frog season 2025

Chorus Frog Survey

It is that time of year! I like doing Citizen Science. The federal ministry, Environment and Climate Change Canada, has been running  ๐ŸธChorus Frog Surveys for a few years now. We began participating in 2020. They are on hiatus for 5 years, and they cancelled it during COVID. Now they are back with limited surveys. I really don't know what that means. 

I have never seen a Chorus Frog, but I've heard them! They lay eggs in vernal pools, in winter melt water, ones which dry up in summer and don't have fish predators in them. (Clever, eh?)

Western Chorus Frog wiki

I programmed my sites onto the map. Then transferred it to my phone. 



This is the map that shows two different populations. The Carolinian population is not at risk. The Great Lakes population is distinct from the green shaded one. The population near us is threatened. 

They are unusual frogs, at least to me. They sound like someone running a finger across the top of a plastic comb.



Head Office, AKA the biologists, email us when they are calling in our area. Usually for two weeks in April. 
 
A few important notes about weather conditions to optimize your chances of hearing the calls for Western Chorus Frogs:
  • Wait until the temperature reaches 10°C before conducting surveys
  • The wind speed should not exceed 20 km/hour during survey.
  • Please conduct surveys when there is no rain, or light rain only.
  • Only go out to listen for them between 10 a.m. and 6 p.m.

Your description of their call was perfect! I feel like I've heard that before, but I can't be sure it was exactly the same.

I would love being out listening for Chorus Frogs. As it is I can hear them in my mind, as with all frogs one of the great sounds of spring.

I am sorry you missed them but glad that you are going to submit your results anyway. That is what Citizen Science is about.
