Way of life
The blue-eyed pigeon has so far been little researched. It inhabits the Cerrado steppe. Occasional observations used to be made in harvested rice fields . The blue-eyed pigeon is territorial and occurs singly or in pairs.
status
In the years 1823 to 1825 Josef Natterer caught the first five copies in Mato Grosso . In 1904 there was evidence from São Paulo . Further historical evidence comes from 1940 and 1941 when two specimens were collected in Goiás . The most recent sightings are all unconfirmed. Two observations were made in the Serra das Araras reserve and at Cuiabá in the state of Mato Grosso during the 1980s . A last sighting is said to have taken place in October 1992 near Campo Grande in the state of Mato Grosso do Sul . The greatest threat is the transformation of the cerrado steppe into eucalyptus plantations and pastureland . BirdLife International estimates the population at between 50 and 250 specimens.
