“Cyanoliseus parakeets are highly intelligent birds that exhibit complex behaviors.”

There is currently only one living species within the Cyanoliseus genus, though evidence exists that other species previously existed. The single surviving member of this genus is the Burrowing Parakeet (Cyanoliseus patagonus), an endangered parrot of the Patagonian region in Chile and Argentina. While more Cyanoliseus species likely roamed these areas long ago, the Burrowing Parakeet serves as the last remaining example of parrots within this group.

The Burrowing Parrot exhibits many characteristics unique to the Cyanoliseus genus. Let’s explore what defines this remarkable group of parrots, spotlight the sole surviving member, and learn what threats Cyanoliseus species face today. Through education and conservation action, we can preserve the legacy of this highly intelligent genus of parakeets.

Species Spotlights

Burrowing Parakeet (Cyanoliseus patagonus)

Also known as the Patagonian Conure, the Burrowing Parakeet or Burrowing Parrot is the only surviving member of the Cyanoliseus genus. This large parakeet measures 30-38 centimeters (12-15 inches) long and bears vivid green plumage accented by a grayish crown and blue flight feathers. Its scientific name comes from its bluish wings (cyan) and smooth feather texture (liseus).

The Burrowing Parakeet inhabits open grasslands, scrublands, and forest edges ranging across southeastern South America. Its native range spans parts of southern Brazil, Uruguay, Paraguay, Bolivia, Chile and southwestern Argentina. These intelligent birds travel in noisy flocks, nest in burrows or tree cavities, and utilize their strong jaws to feed on seeds, nuts, fruits, buds, and some insects.

As the sole remaining Cyanoliseus species, the Burrowing Parakeet serves as an important “poster bird” for conservation. While not currently endangered, it faces threats from habitat loss and trapping for the pet trade. Protecting grassland ecosystems and regulating capture will help preserve populations of this unique parakeet into the future.

Other Cyanoliseus Species

While the Burrowing Parakeet remains the only living member of the Cyanoliseus genus, studies show that up to 3 other species may have existed prehistorically. Based on genetic evidence and some fossil data, scientists have proposed there were formerly Cyanoliseus species in the Caribbean, the Andean region, and southern South America respectively.

“Up to 3 extinct Cyanoliseus species likely existed before modern times.”

Due to factors like climate shifts or human activity, these hypothetical Cyanoliseus species all faced extinction prior to recent history. As a result, the Burrowing Parakeet persists as the sole surviving example of these specialized parakeets. By protecting this species and its grassland habitat, we pay respect to its potentially lost evolutionary cousins within the Cyanoliseus genus.

Behavior and Intelligence

The Burrowing Parakeet exhibits many complex behaviors reflecting advanced intelligence for a bird. All parrots display brighter than average bird brains, but Cyanoliseus species seem exceptionally smart, social and communicative.

Communication

Burrowing Parakeets have a repertoire of contact calls, alarm calls, and flight calls used to maintain group cohesion. Their loud squawks of “ri-ka-tek!” ring out as they fly in large flocks or roost communally in trees. Researchers have identified over a dozen distinct vocalizations from these highly social birds.

Bonding and Breeding

These parakeets are monogamous breeders that mate for life. Paired couples synchronize actions closely as they prepare nests together in burrows or tree cavities. Both parents share brooding and feeding duties once their 4-6 eggs hatch after about 26 days of incubation. The bonded pairs preen each other often and may refuse other mates if one dies.

Foraging and Feeding

Burrowing parakeets have strong jaws and beaks evolved to crack hard nuts and seeds. They display intelligence seeking the most energy-rich foods across grasslands and forests. Their range of dietary items also speaks to behavioral flexibility. As the saying goes, “many crops, one stomach!”

Captivity and Training

An early 20th century psychologist studied captive Burrowing Parakeets completing color and shape matching tasks. He concluded they matched simians in intelligence, outperforming dogs. Today, pet Burrowing Parakeets are noted as playful, curious companions open to bonding, learning tricks and communicating. Their intelligence makes them highly responsive to patient training.

Overall the behavioral richness of the Burrowing Parakeet provides a window into the former diversity of Cyanoliseus species before extinction. Protecting this species allows continued study of its advanced intelligence within the parrot family.
