Boonsong Lekagul (15 December 1907 – 9 February 1992) was a Thai medical doctor, biologist, ornithologist, herpetologist,[1] and conservationist.
He was born at Songkhla in southern Thailand and received a medical degree from Chulalongkorn University in Bangkok in 1933.
At first a keen hunter, he became a strong conservationist as he saw Thailand's forests and wildlife becoming fragmented and destroyed.
In the mid-1950s, he and the ACW lobbied for a bird sanctuary on the banks of the Chao Phraya River to protect the only known nesting site in Thailand of the openbill stork.
