Bull Frogs - I swear I heard Barry White in the background

I don't see Bullfrogs that often.... When I do, they are usually jumping in the water... away from me... Yesterday when I was at Lk. St. Clair Metropark (slowly getting used to the new name) in the afternoon, they were all in a mating frenzy in the small pond near the South Marsh.... The sound was incredible and I was able to approach the frogs closely... they had other things on their mind.... It was interesting watching their behavior... Not being an expert on Amphibians, I found it interesting that they all had the same thing on their mind at the exact same time....  click to enlarge
