Extension of the Known Range of the Gray Treefrog, Hyla versicolor, in Northwestern Ontario

Wayne F. Weller

Abstract


I present the first documented records of Gray Treefrog, Hyla versicolor, from the Red Lake area of Kenora District in northwestern Ontario. A photograph of H. versicolor was taken at a locality west-northwest of the town of Red Lake in 2007 and another east of Red Lake in 2009. H. versicolor choruses were heard at 11 localities east and southeast of Red Lake in June 2008, and were tape recorded at 5. These seven documented records are 46-56 km north-northwest of the previous most northern voucher, west of the town of Ear Falls, and they represent the most northern locations known for H. versicolor in Ontario.
