![]() Predators of adult frogs include water bugs, garter snakes, small mammals, and birds. Prey is located by vision, then a large sticky tongue is used to catch the prey and bring it into the mouth to eat. Recent studies not yet published (2019) show that Cascades frogs live much longer than the 5-7 years previously thought.Ī quiet series of low grating clucking noises.Ĭalls at night and also during the day from above and under water.ĭiet is not well known, but probably consists of a wide variety of invertebrates. In the Oregon Cascades, both male and females are thought to live less than 5 years, sometimes reaching 7 years (Lanoo 2005). When frightened, a frog typically hops into water and swims away to escape, usually to the opposite shore or to the bottom where it goes head first into silt and mud.Īdults are not territorial, but males behave aggressively towards other males during the breeding season. ![]() Occurs in areas covered by winter snow, hibernating throughout winter buried in mud under several feet of water or in saturated areas around ponds. Typically found near water at higher elevations. Tadpoles grow to about 2 inches in length (5 cm.)Ĭolor is dark brown, with copper to pinkish speckling, golden coloring on the sides and a finely speckled tail. The sides are cream colored, and there is dark mottling on the groin.Ī dark face mask is present with a light upper jaw stripe extending to the shoulder. The eyes are positioned directly laterally - they are oriented outward.īrown, copper, tan, to olive green above, yellowish below and on the back of the legs.īlack spots with distinctly-marked edges are usually present on the back. Raised ridges on the sides (dorsolateral folds) are distinct. (Stebbins, 2003)įemales grow up to 3 inches long (7.5 cm) males up to 2.25 inches (5.8 cm.)Ī medium-sized frog with a slim waist, long legs, smooth skin, and reduced webbing on the hind feet. More pictures of this frog and its habitat are available on our Northwest Herps page.Īdults are 1.75 - 3 inches long from snout to vent (4.4 - 7.5 cm). Views of some of the many egg masses in a breeding pond in the Washinton Cascades Mountains. 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.Ī 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. ![]() Male frogs chase each other around in the breeding pond, chattering and clucking. Several adult male frogs make calling sounds in the Washington Cascade Mountains.Īn adult male frog floats on the breeding pond, trading calls with two other frogs heard in the background. Views of several Cascades frogs in their habitat, a creek in the mountains of Siskiyou County.Ī look at a Casacdes Frog breeding pond high in the Washington 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.
