I went to Red lock in the Cuyahoga Valley tonight. The main pond was all but silent with 1 Wood frog calling. The vernal pools to the east had Wood frogs and Chorus frogs. There are 2 ponds and 1 vernal pool North East of the main pond, each had a diffent species calling and all had Spring Peepers. The first had mainly Chorus, the next had Peepers and Leopard an the last had Wood frogs. I have never heard Leopard calling so soon. We are only 2 days into 50 degree weather and the last stretch above 40 degrees was for 2 days ending on March 11th. I will get some sound recording links up within the next several days.
