Arica y Parinacota Region
In 2018, researchers Patrich Cerpa, Fernando Medrano and Ronny Peredo found the ectoparasite stick-tight flea "Hectopsylla psittaci" on two birds out of ten captured in Pampa de Chaca within the Arica y Parinacota Region. Both specimens were found in the lorum on each bird. The turkey vulture "Cathartes aura" served as a possible source for the transition between hosts, as Cerpa, Medrano and Peredo observed the two nesting in the same colony. Researchers Rodrigo Barros et al. described the bird as "one of the least known seabirds in the world".
