I spent part of the afternoon at Cromwell Valley Park today, and for most of that time I literally didn't hear a peep. The only area with any real activity was along the south entrance road. There was a mixed flock of sparrows about 2/3 of the way to the first bridge along the tree line on the right side of the road. There were about a dozen Juncos, several Song Sparrows, several Chipping Sparrows, one Field Sparrow and one pretty American Tree Sparrow. I posted a couple distant photos of the Tree Sparrow on my flickr page. http://www.flickr.com/photos/27381338@N03/5188441584/
