We report observations of Gray Jays ( Perisoreus canadensis ) appearing to consume larval Long-toed Salamanders ( Ambystoma macrodactylum ) in a drying subalpine pond in Oregon, USA. Corvids are known to prey upon a variety of anuran amphibians, but to our knowledge, this is the first report of predation by any corvid on aquatic salamanders. Long-toed Salamanders appear palatable to Gray Jays, and may provide a food resource to Gray Jays when salamander larvae are concentrated in drying temporary ponds.
