Species Amazona gomezgarzai

The Blue-winged amazon (Amazona gomezgarzai), is a species of amazon parrot found in the Yucatan Peninsula, Mexico. Described in 2017 in the journal PeerJ.

Amazona gomezgarzai has an average body length of 25 cm and a body weight of 200 g. It is characterized by distinct sexual dimorphism, with males larger than females. Depending on the gender, the wings' length is 170-175 mm and the tail's length is 84-90 mm. Most of the body is covered with green feathers. However, these parrots differ in size and detail of the colors of the plumage from other Amazons found on the Yucatan peninsula (White-fronted amazon and Yucatan amazon).

The forehead and the ring around the male's eye are red. The red color is limited to the forehead, when speaking about female. Remiges (primaries and secondaries) are blue and green. Tail's green with blue and green ends of the feathers. Feathers of the tail with red spots on the inner side.

They produce distinctive loud, sharp and repetitive sounds that resemble the hawk, the natural enemy of these birds. It is possible that this sound is used to alert other birds. The syllables are 3-5 times longer than those of White-fronted amazon and Yucatan amazon.

They live in groups up to a dozen individuals. Couples and their adult offspring tend to remain together as a group.

Genetic analyzes based on mitochondrial DNA indicate close affinity with the White-fronted amazon and suggests that Blue-winged Amazon could be a subspecies of the first one. However, this may be due to the introgression of mitochondrial DNA or too small variation in the genetic markers examined. It is possible that the new species has evolved relatively recently (about 120,000 years ago) within one of the white-fronted amazon population.

The species was discovered in 2014 by ornithologist Dr. Miguel Gómez Garza during one of his expeditions on the Yucatan Peninsula.
