High in the mountains of Chiapas, the southernmost state of Mexico, a male Highland Guan is performing his territorial display. The Highland Guan perches on a tree-branch, whistles, and then glides on vibrating wings. The resulting wondrous sound is like no other. The bird’s display creates a sound emblematic of the cloud forest of El Triunfo Biosphere Reserve. Clouds and fog roll frequently through the reserve, creating a lush forest wonderland. Cloud forest makes up less than 1% of the world’s forest, and its conservation is crucial. At El Triunfo, the display of the Highland Guan testifies to a conservation success.
