As we approach the pond a silence settles in as if no souls were there. Then first one voice followed by another voice and another join in. Soon a full chorus of the entire symphony booms out its arrangement to delight our ears. I wonder how many species we will hear this year. One? Three? Five? Help us keep track of the songsters in and near our ponds desperately calling for company! Meet at the Bretschnieder Park/Audubon parking lot on the north side of Pioneer Trail a few hundred yards east of Page Rd. in Aurora.
