Tips for Birdwatching on the Big Island

1. Best Time: Early morning and late afternoon for feeding flocks.
2. Locations:
   • Cattle Egret: near pastures, golf courses, and roadsides.
   • Great Egret: near ponds, rivers, and wetland areas.
   • White Tern: coastal cliffs, Kahaluʻu Beach, Hilo shoreline.
3. Photography Tips:
   • Use long lenses for egrets in wetlands.
   • For White Terns, high shutter speeds capture mid-air grace.
4. Conservation: All three are protected under Hawaiʻi state laws, but Cattle Egrets are non-native and extremely abundant.
