| A look at a Cascdes Frog breeding pond high in the Cascades, including the pond surrounded by melting snow, male frogs in calling position, two calling males, and two episodes of male frogs attempting to mount other males with sounds of protest. | Several adult male frogs make calling sounds in the Washington Cascade Mountains. | An adult male frog floats on the breeding pond, trading calls with two other frogs heard in the background. | Male frogs chase each other around in the breeding pond, chattering and clucking. |

| The bottom frog of this pair in amplexus (probably a female) makes a few release calls as it tries to shake off the male on its back. | A male frog discovers another frog (probably a female that has already laid eggs) grabs on to her, and is carried around the pond as she tries to shake him off. | Views of some of the many egg masses in a breeding pond in the Washinton Cascades Mountains. | |
