Breeding activities, population levels, movements, and pond preferences were investigated for the Pacific treefrog, Hyla regilla, during two breeding seasons at five small ponds in northern Idaho. The number of males declined from approximately 360 in 1976 to approximately 160 in 1977. Individual males spent more time at the ponds in 1976 than in 1977, and the average snout-vent length for both sexes was less in the first year than in the second. The dominant coloration of males shifted from nongreen in 1976 to green in 1977.
