Birding Tips

  1. 1

    Check rocky shorelines and jetties at low tide for shorebirds.

  2. 2

    Scan offshore waters with a spotting scope for seabirds and waterfowl.

  3. 3

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

  4. 4

    Onshore winds can push pelagic species closer to shore, making post-storm days excellent for rarities.

  5. 5

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