Birding Tips

  1. 1

    Scan the water surface methodically for diving ducks, loons, and grebes.

  2. 2

    Check the shoreline and mudflats for shorebirds and wading birds.

  3. 3

    Acclimate to altitude before hiking to high-elevation birding spots.

  4. 4

    A spotting scope is essential here — many waterbirds stay far from shore and are difficult to identify with binoculars alone.

  5. 5

    Winter months bring peak waterfowl diversity — visit November through February for the best duck and goose viewing.
