Erythrism in Spring Peeper (Pseudacris crucifer) in Maritime Canada

Donald F. McAlpine, John Gilhen


We document three cases of erythrism in Spring Peeper (Pseudacris crucifer) in New Brunswick and Nova Scotia. Although the source of erythrism in Maritime P. crucifer remains uncertain, the occurrences reported here demonstrate this colour morph to be a widespread, although apparently rare, form in the Canadian Maritimes region.
