Birds: We've got lots - over 320 species have been recorded. To the non-expert, birds are often just mysterious whistles, trills and calls, or a flutter of wings and a glimpse of colour. Patience is needed,good binoculars and a bird guide help. Roadsides, the old golf course, grasslands and the watching towers are good places to start . Hornbills are quite easy to spot, and hear the "gak gak gak" laugh of the Indian Pied (often seen in big flocks near Nong Pak Chi Tower in the evenings), or the deep resonant "gok…gok" of the Great Hornbill (usually seen in pairs or alone, the biggest of Khao Yai's hornbills)
