I also saw Beach Kingfisher but was not able to shoot it by my camera. I used Canon 200D with Tamron 150-600 mm.
In addition to birding, I also enjoyed snorkeling at the beach. I saw a lot of species of fish and coral reef. There were wobbegong, butterflyfish, stonefish, Striped Surgeonfish, anemonefish, and other marine creatures like burrowing clam, christmas tree worm and crab.
