Issued in 2025, this stamp depicts the endangered horned guan (Oreophasis derbianus). It can be found in areas of Mexico, Guatemala and maybe Honduras. It feeds on fruits, leaves, flowers and possibly insects. A characteristic feature of the species is the red fleshy 'horn' on its forehead.

Thank you Lando!
