Birding Tips

  1. 1

    Bring waterproof boots for marsh trails and muddy edges.

  2. 2

    Scan the edges of open water for herons, egrets, and rails at dawn.

  3. 3

    Carry extra water and sun protection; mornings are the prime birding window.

  4. 4

    Bring insect repellent — wetland areas can have significant mosquito activity, especially in warmer months.

  5. 5

    Bring quality optics — a good pair of binoculars (8x42 or 10x42) makes all the difference in species identification.
