This was an interesting evening. I heard the first chorus for the season by Brandywine and they were Chorus frogs. Their call has always reminded me of a finger drawn across a comb. As I recall, this area has had a good population of these frogs for some time. Back when the beaver dam next to the Cuyahoga line just north of Vaughn road was filled with water, these were the first to call. Another strong area is in Hinkley, OH at the Whipps ledges and State road intersection. The next chorus was a small population of Spring peepers, about a mile south. The most interesting call, however, was the call of several Night hawks (Chordeiles minor). I have never heard them so early in the year. I didn’t think there was enough bugs flying around to eat. (Edit 4-10-2011) Was just informed that they are actually Woodcock calls! Now it makes sense!
