Field notes

  • When threatened or highly excited, this bird can produce a unique wheezing or 'huffing' sound through its nostrils.
  • The species is known for its bronze or olive iridescence on the mantle and wings, which shimmers under direct sunlight.
  • It is the most widely distributed member of the Pionus genus, showing high adaptability to human-altered landscapes.

Subtropical and tropical dry forests, Atlantic forest, gallery forests, and wooded savannas.
