A trip to this unique place is by special permit from the Bergen Swamp Preservation Society and will feature nesting birds. The mix of vegetation zones provides secluded nesting habitat for the usual western NY species as well as those more characteristic of the Canadian zone such as Blue-headed Vireo, Hermit Thrush, Magnolia, Blackburnian, Black-and -White, Canada, and Nashville Warblers. This is a walking trip of 2 - 5 miles on variably wet and slippery corduroy trails that must be followed closely for safety reasons and because of the fragile habitat. Sturdy boots (rather than sneakers) are STRONGLY recommended, and hiking or ski poles may be useful. Massasauga rattlesnakes are VERY rarely encountered. Parking at the trailhead is limited, so we will meet in the parking lot of the Sunoco Gas Station at the junction of Routes 33 and 19 at 7:30 a.m. Drive about 20 miles west of Rochester on I-490 to exit 2. Turn right (west) on Route 33 and go about one mile to the junction with Route l9. Turn left (south) and then immediately left into the parking lot. Park near the "Drop Off” sign.
