Origin, geographical range and distribution
The Baudo oropendola is endemic to Colombia in South America. They are known "from the foothills and lowlands around the serranías de los Saltos and de Baudó, Chocó, north-west Colombia" (BirdLife International).There are records of sightings of a nesting colony at the headwaters of the río Acandí in 1991 (Renjifo et al. 2002), two individual birds in north of Ensenada de Utría National Park and a group in the Siviru and Tipicay river basins.
The Important Bird and Biodiversity Areas (IBA) of these Baudo oropendola species in Colombia is Parque Nacional Natural Ensenada de Utría.
Ecosystem and habitat
The Baudo oropendola species have high forest dependence. They normally occur in altitudes between 100 to 365 meters.The natural ecosystems and habitats of these species include tropical and subtropical moist lowland forests, secondary growths, river valleys and forest edge along sandy-soiled coastal plain.
Diet and feeding behavior
The diet of the Baudo oropendola species consists mainly of fruits and insects. They forage for fruits and insects in the canopy in small groups.Reproduction and breeding habits
The breeding season of these Baudo oropendola species is probably during May and June (Jaramillo and Burke 1999). One nesting colony was observed in March 1991.These species are colonial breeders and the nests are suspended from the lateral branches of tall trees and palm trees.
Migration and movement patterns
The Baudo oropendola species are non-migratory resident birds.Post breeding, the juveniles may disperse and establish in new locations within the range. Within their range they may make local movements for feeding and breeding.

The overall population trend of the species is considered to be decreasing.In most of its range, this species is reported to be rare and localised. The generation length is 4.6 years. Its distribution size is about 4,570 sq.km.
Ecosystem degradation, ecosystem conversion, deforestation, logging operations, road laying across the forests and capture for pet-trade are the main threats that may endanger the survival of the species.
