I have been reading about frogs’ habitat and behaviour in the past months for my book project. Yesterday I returned to a marsh in my area where I had previously heard some frog calls (this is mating season). As I was quietly waiting for some action, frogs started calling each other. It became quite loud as more of them joined the chorus. It was a surreal moment because I was completely surrounded by frogs, some very close to me, yet I could not see any of them. Listen and tell me if you can identify them.
Update: They have been identified as Pacific Treefrogs (Pseudacris regilla) by Brent Matsuda, co-author of Reptiles and Amphibians of British Columbia.
