| A male Northern Pacific Treefrog calls while floating on a pond in the Cascades Mountains of Washington on a sunny Summer day. This is the two-part advertisement call. |
A male Sierran Treefrog makes the one-part or enhanced call from the edge of a small temporary snow-melt pond at 8,600 feet elevation in Alpine County. This species is identical in sound and appearance to the Northern Pacific Treefrog. | A male Northern Pacific Treefrog on a pond in the Cascades Mountains of Washington responds to the frog-like sounds made by a human. When the human sounds are similar to the territorial call, the frog reponds likewise. |
