The Great Marsh

August 15, 2021 @ 8:00 am - 11:00 am EDT

For: Summer Resident Birds

Place: 28 Moores Road, Elverson, PA, 8:00 a.m.

Leader: Mike Coulter. If you plan to attend please email the Great Marsh Institute at to let them know to expect you.

Note: Join local birding expert Mike Coulter as he guides us through the Great Marsh, an ancient periglacial marsh and the largest marsh in Southeastern Pennsylvania. August may be the quietest time of year as breeding birds are no longer competing for or defending territories, but it certainly does not mean that there is not some good birding action to be had. GMI has recorded 76 species in August in the past and we are hoping to add to that number as coverage has been light during this month in past years. Herons and Egrets are on the move in their post breeding dispersal. We will be keeping our eyes open for Great Egret and Little Blue Herons which have made appearances in the past. Southbound shorebird migration is under way and depending upon water levels we are likely to encounter a variety.

This event is hosted by the Great Marsh Institute, a non-profit with the mission of supporting scientific studies and educational opportunities for all! This event is free, but donations of any amount are welcome to support the Institute! For full trip details see here. This will be about a 3 hour walk. Conditions could be muddy and very wet so wear appropriate footwear.

Please note that the property is private but you can always visit during our planned trips.

Directions: The marsh is off of Rt. 401 four miles northwest of Rt. 100 at Ludwig’s Corner. Lat/Long = 40.127651, -75.767697 or use 28 Moores Road for GPS directions. Meet at the grassy parking area at the top of the hill near 28 Moores Road. Once you turn off of Rt. 401 on to Moore’s Road proceed 1/4 mile along the gravel road. You will cross a bridge and at the 1/4 mile mark make a right up the hill on the paved part of the drive. This is the first right after the bridge. At the top of the hill you should see other cars parked in the meeting area.
