Birding Tips

1
Bring waterproof boots for marsh trails and muddy edges.
2
Scan the edges of open water for herons, egrets, and rails at dawn.
3
Visit during mid-May for peak warbler migration.
4
Bring insect repellent — wetland areas can have significant mosquito activity, especially in warmer months.
5
Bring quality optics — a good pair of binoculars (8x42 or 10x42) makes all the difference in species identification.
