Northern red-legged frogs dispersing near Olga

Northern red-legged frogs were observed four times between August 24 and September 15 near Olga and Anacortes, Washington, during the post-breeding dispersal phase. In Washington, these state-listed threatened frogs breed in February and March, then migrate from breeding ponds to terrestrial forest habitat to feed and prepare for overwintering.¹ September observations document them in dispersal, moving into riparian zones and moist forest cover within roughly one kilometer of water.¹
