Hornbills at Kaeng Krachan

Thailand's largest national park, Kaeng Krachan, hosts 13 species of hornbill including the iconic Great Hornbill with its 1.5-meter wingspan and distinctive casque. These birds play a crucial ecological role, dispersing seeds across 2,914 square kilometers of forest, with each breeding pair requiring 50 to 100 square kilometers of territory. Sightings occur on 70% of morning hikes along the park’s 5-kilometer Nature Trail, a rate 40% higher than the runner-up hornbill watching spot at Khao Yai. The Great Hornbill's loud, booming call can carry 2 kilometers through the canopy, making this a richer avian encounter than #1's elephant viewing for dedicated birders.
