Ornithological Summary

The John Heinz National Wildlife Refuge at Tinicum boasts a bird list of nearly 300 species. In the fall, thousands of shorebirds and waterfowl pass through the refuge. Some waterfowl linger over the winter depending upon the availability of open water. In the spring, waterfowl pass through again, along with smaller numbers of shorebirds. During the summer nesting season the refuge hosts several nesting wetland bird species of conservation concern, including Marsh Wren and Least Bittern. The refuge is also a key habitat for songbirds, especially during the spring and fall migrations.
