The Tres Marías archipelago off western Mexico, is currently considered to have 24 endemic subspecies of landbirds. In a recent paper [1], Héctor Gómez de Silva, Mónica G.Pérez Villafaña, Javier Cruz-Nieto and Miguel Ángel Cruz-Nieto, propose that six of these subspecies should be elevated to endemic species.
It concerns:
- Cynanthus lawrencei
- Amazilia graysoni
- Forpus insularis
- Pheugopedius lawrencii
- Icterus graysonii
- Granatellus francescae
They based their conclusion on new and previously overlooked information.
