Related Species

The phylogenetic relationships of trogons were investigated by Espinosa de los Monteros (1998), based on DNA sequence data for two mitochondrial genes (cytochrome b and 12S ribosomal RNA), and by Moyle (2005), using DNA sequence data from both nuclear ((RAG-1) and mitochondrial (ND2) genes. Both Espinosa de los Monteros (1998) and Moyle (2005) recovered a clade of trogons that includes Black-throated Trogon (Trogon rufus), Elegant Trogon (Trogon elegans), Mountain Trogon (Trogon mexicanus), Collared Trogon (Trogon collaris), and Masked Trogon (Trogon personatus). Espinosa de los Monteros (1998) identified elegans and rufus as sister taxa. Moyle (2005), on the other hand, identified rufus as basal to all other members of this clade, and elegans as basal to all but rufus.
