Pacific treefrog, Hyla regilla, found at the American River, California.
Bright sunny day.
He and a friend treated us to a show of their voices. They are very loud and make their song by expanding their balloon like throats. It is a fascinating thing to see.
Here’s a video that I shared on my other blog that has the frogs croaking at 25 seconds and 50 seconds into the video.

The video is terrible but the audio is fantastic. They really were as loud as they sound in the video.
Handbook of Nature Study, page 186
“The frog may be studied in its native situation by the pupils or it may be brought to the school and placed in an aquarium; however, to make a frog aquarium there needs to be a stick or stone projecting about the water, for the frog likes to spend part of the time entirely out of water or only partially submerged.”
On pages 178 and 179 of the Handbook, Anna Comstock talks a little about a different variety of tree frog and shows a few photos.
“It is by means of these sticky, disclike toes that the animals hold themselves upon the tree trunks or other upright objects.”
Here is a nature journal entry my son did last summer of another Pacific treefrog that we observed.
We are going to be able to identify this little creature now when we hear his call and we feel privileged to have had this experience.
