Welcome to the first sound(e)scape mini-ep. Between each Sheltered Spring episode we'll be cleansing your aural palate with three minutes of soundscape recording. This first recording was done at night next to an Aptos, CA neighborhood backyard frog pond. This track features the Sierran treefrog (Pseudacris sierra). Or a bunch of them, that is. Here's what Gary Nafis says on his excellent californiaherps.com website:
"Advertisement calls are heard during the evening and at night, and during the daytime at the peak of the breeding season.
Males produce two different kinds of very loud advertisement calls: a two-parted, or diphasic call, typically described as rib-it, or krek-ek, with the last syllable rising in inflection, and a one-part, or monophasic call, also called the enhanced mate attraction call.
They also produce a slow trilled encounter call, a release call, and a land call, which is a prolonged one-note sound that is produced much of the year, especially during the beginning of the fall rains."

Can you hear any of the calls he describes?
