About
The Olive-winged Trumpeter is a newly split species, which was previously lumped together with Psophia viridis, the Dark-winged Trumpeter.
The trumpeters diverged on their own 50.2 Million years ago, splitting from all other birds in the Paleogene Period. Trumpeters are so called because they call loudly when alarmed. Major rivers appear to form a hard barrier at the edge of the species’ range, and this separation may have been the catalyst to the speciation events within the trumpeters. Unfortunately, this species is suspected to lose 32-54% of its extent of suitable habitat in the Amazonian portion of its range over 31 years as projected in 2002. This species is suspected to decline by 62.3% over the next three generations. The deforestation of the Amazon basin is mainly due to land cleared for cattle ranching and soy production. Conservation actions are underway with many large protected areas creating a mosaic of conservation units in the Amazon Basin. The protection of this species habitat should be a priority for the safe guarding of future populations of the Olive-winged Trumpeter.
