Orinoco Goose
The Orinoco Goose (Oressochen jubatus). Read in Spanish
Physical Appearance: The Orinoco goose has a unique and striking appearance. It is a medium-sized goose, typically measuring around 69 cm (27 inches) in length. Their plumage is predominantly dark grey, with a lighter grey and white coloration on the head and neck. They have large, webbed feet and a stout bill.
Habitat and behavior: These geese prefer freshwater habitats, especially those with dense vegetation where they can find cover. 500-2600 m. They are not highly migratory and tend to be sedentary, residing in their preferred wetland areas year-round. Orinoco Geese are known to be social birds, often forming large flocks, particularly during the breeding season. Grazes on plant matter.
Breeding: Orinoco Geese typically breed between October and March in Colombia. They construct nests on the ground, near the water's edge, using plant material and lined with down feathers. Females typically lay around 7-9 eggs, which they incubate for approximately 30 days. Both parents participate in raising the young.
Conservation: Orinoco Geese face threats from disturbance from human activities. Nevertheless, they are currently listed as a species of concern/vulnerable by the International Union for Conservation of Nature (IUCN).
Distribution
The Orinoco Goose (Oressochen jubatus) has a distribution within Colombia, primarily in regions associated with wetland habitats. Here is more detailed information about the distribution of the Orinoco goose in Colombia:
- Geographic Range: The Orinoco goose can be found in various parts of Colombia, particularly in the eastern and southeastern regions of the country. This includes areas within the Orinoco River basin and the vast Llanos savannas, which are characterized by wetlands, rivers, floodplains, and grasslands.
- The Llanos Region: The Orinoco goose is known to inhabit the Llanos region or the Los Llanos Orientales, which encompasses parts of eastern Colombia and western Venezuela. This vast lowland area is dominated by grasslands, wetlands, and seasonal flooding, creating suitable habitats for the species.
- Wetlands and Rivers: Within Colombia, the Orinoco goose is typically associated with wetlands, rivers, and their surrounding areas. It can be found in marshes, flooded grasslands, and wooded riversides that offer a combination of open water, suitable vegetation, and nesting sites.
- Conservation Areas: Several protected areas and national parks in Colombia may serve as important habitats for the Orinoco goose. For example, wildlife reserves such as the El Tuparro National Natural Park and the Serranía de la Macarena National Natural Park, both located in the Orinoco River basin, are known to support populations of the Orinoco goose.
- Elevational Range: The Orinoco goose is primarily a lowland species, typically found in elevations up to 1,500 meters above sea level. This species prefers the low-lying floodplains, wet grasslands, and river habitats found in the lowlands rather than higher elevation areas within Colombia.
It is worth noting that more detailed information about the specific distribution, population size, and habitat preferences of the Orinoco goose in Colombia may be available through scientific studies, bird surveys, and local ornithological organizations that focus on bird conservation within the country.
Taxonomy
The Orinoco Goose (Oressochen jubatus) belongs to taxonomic classification mentioned below:
- Kingdom: Animalia (animals)
- Phylum: Chordata (chordates)
- Class: Aves (birds)

The taxonomic classifications may be subject to updates or revisions as new research and genetic studies emerge. If there have been any recent taxonomic changes specific to the Orinoco goose in Colombia, referring to scientific literature, taxonomic databases, or regional ornithological organizations may provide the most up-to-date information.
Vocalization
The Orinoco Goose (Oressochen jubatus) is known for its unique vocalizations, which consist of a variety of calls and sounds. Here are some vocalizations associated with the Orinoco goose:
- Honking: The most commonly heard vocalization of the Orinoco goose is a distinctive honking sound. The honk is a loud, resonant call that is often described as a low-pitched "honk" or "huhonk." This call is believed to serve as a means of communication between individuals, especially during flight or to establish territory boundaries.
- Trumpeting: The goose also produces a characteristic trumpeting sound, which can be a series of short, sharp notes or a prolonged, melodious sound. This vocalization is often associated with courtship or territorial displays and may serve as a signal to attract mates or communicate with other geese in the vicinity.
- Hissing: When threatened or alarmed, the Orinoco goose may emit a hissing noise. This sound is created by expelling air through its bill and is often accompanied by defensive posturing, such as raising the head, extending the neck, or fluffing the feathers as a warning to potential threats.
