I birded Seneca through the migration. The best trail I found is is located at the edge of the visitor center parking lot nearest the entrance. It leads on to the power line right-of-way which was good for blackpoll and prairie warblers, yellowthroats, towhees and an occasional cuckoo. The trail then follows Seneca creek which is good for thrushes, acadian flycatchers and vireos. The trail loops and comes back on to the powerline along a stream which is heavily vegetated. I spent soem time at this spot during the spring and I saw white eyed vireos, indigo buntings, prairie warblers towhees and song sparrows. You can return to the woods from there or continue along the powerline. I highly recommend the site as well as the Meadowside Nature Center by Lake Frank. Good Luck! Chris Barnard
