Javan Trogon

The Javan trogon is a bird species in the family Trogonidae endemic to western Java, Indonesia. It was previously grouped with the Sumatran trogon as a single species, known as the blue-tailed trogon. However, differences in size, weight, and plumage have led to their classification as separate species. Both species were once included in the genus Harpactes alongside other Asian trogons, but due to differences in plumage, they have been reclassified into their own genus, Apalharpactes.
