Birding Tips

  1. 1

    Start birding at dawn when desert birds are most active before the heat.

  3. 3

  4. 4

    Check eBird hotspot data before visiting to see recent sightings and what species are being reported.

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