Birding Tips

  1. 1

    Scan fence posts and utility wires for perching raptors and kingbirds.

  2. 2

    Walk field edges at dawn when sparrows and grassland species are most vocal.

  3. 3

    Time your visit during the first week of May for maximum species diversity.

  4. 4

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

  5. 5

    Waterproof boots are recommended as trails near marshes can be muddy, especially after rain.
