We have lots of critters up at our float cabin on Powell Lake. Most of them are annual returnees, but this year I saw my first Pacific Chorus Frog (Pseudacris regilla). I went to water my zucchini plant and there he was, sunning himself on one of the large leaves.

The Pacific Chorus Frog is common in Southern BC west of the Rockies and on Vancouver Island. It can be found in the woods, meadows, and even in urban areas. They come in light grey, tan, bronze or bright emerald green. You can see which kind I found.

They are small frogs, up to 5 centimetres in length. A distinguishing mark is the mask-like stripe that starts at the nostrils and continues all the way to the shoulder.

Pacific Chorus Frogs breed mostly in temporary water bodies that dry up later in the summer months. This prevents enemies such as fish and bullfrogs from raiding their eggs and young. Powell Lake has a good sized population of invasive bullfrogs, garter snakes and trout, so breeding here must be a challenge.
Mating season comes in the spring. Next year I'll have to listen more carefully for their krek-ek song. -- Margy
