Saving the Blue-Rumped Parrot: Behavior Conservation and Demography

The Blue-rumped Parrot, scientifically known as Psittinus cyanurus, is a captivating species of parrot that can be found in parts of Southeast Asia. This bird’s distinct blue rump and lime green belly make it an easily identifiable species.

In this article, we will explore the identification, plumage, and molts of the Blue-rumped Parrot.

Identification

Field Identification

The Blue-rumped Parrot’s distinct blue rump and lime green belly make it easy to identify in the field. However, it can be often confused with the Blue-crowned Hanging Parrot, which is smaller in size and has a blue crown instead of a blue rump.

Additionally, the Blue-eared Barbet, which is similar in size and has a blue face, can also be misidentified as a Blue-rumped Parrot.

Similar Species

The Blue-rumped Parrot shares characteristics with several different parrot species. For example, the Plum-headed Parakeet has a similar blue rump, but the rest of its body is a bright pink.

The Blue-throated Parakeet also has a similar body coloration, but has a blue throat and chest rather than a blue rump.

Plumages

The Blue-rumped Parrot has a unique and distinctive coloration that stands out in its environment. Adult birds have a greenish-yellow crown, a blue rump, and a lime-green belly.

The wings and back are a deeper green color. Additionally, the beak is grey, and the eyes are orange.

Molts

Unlike most other parrot species, the Blue-rumped Parrot does not undergo a complete molt every year. Instead, they go through a partial molt, during which they replace a few feathers at a time.

These molts occur in both sexes and happen irregularly throughout the year, depending on the individual bird. In conclusion, the Blue-rumped Parrot is a beautiful and unique parrot species that can be found in Southeast Asia.

Its distinctive blue rump and lime green belly make it an easily identifiable bird in the field. The species is also distinguishable from other similar parrot species, and they undergo a partial molt rather than a complete molt.

It is important to appreciate and protect this beautiful species and its unique characteristics.

Systematics History

The Blue-rumped Parrot, Psittinus cyanurus, has undergone several changes in its taxonomy since its discovery. Initially classified as a subspecies of the Blossom-headed Parakeet (Psittacula roseata), it was later reclassified as a separate species.

Today, it is classified in the Psittinus genus along with the Echo Parakeet (Psittinus echinatus) and Grey-headed Parakeet (Psittinus bromheadensis).

Geographic Variation

The Blue-rumped Parrot has a wide distribution range throughout Southeast Asia, from Myanmar in the west to Indonesia in the east. Along its distribution range, the species displays geographical variation in its plumage and size.

Birds in the western part of their range tend to be larger and have darker plumage, whereas birds in the east are smaller and have lighter plumage.

Subspecies

Based on geographical variation, the Blue-rumped Parrot is currently recognized as having two subspecies:

1. P.

cyanurus cyanurus: This subspecies is found in mainland Southeast Asia, including Myanmar, Thailand, Laos, Cambodia, and Vietnam. 2.

P. cyanurus abbotti: This subspecies is found on the islands of Sumatra and Borneo.

The subspecies differ in size, with P. c.

abbotti being slightly smaller than P. c.

cyanurus. The former also has a brighter green plumage on the upperparts, while the latter is generally darker.

Related Species

The Blue-rumped Parrot is part of the Psittinus genus, which includes two other parrot species: the Echo Parakeet (Psittinus echinatus) and Grey-headed Parakeet (Psittinus bromheadensis). The Echo Parakeet is endemic to the island of Mauritius and was once on the brink of extinction due to habitat loss and predation by introduced species.

Today, with conservation efforts, the population has slowly grown. The Grey-headed Parakeet is found in the Solomon Islands and has a broad range of habitats, from mangroves to primary rainforests.

Historical Changes to Distribution

The distribution range of the Blue-rumped Parrot appears to have changed over the years, likely due to habitat and range fragmentation. The species was once widely distributed across many nations in Southeast Asia, including Singapore and Peninsular Malaysia.

However, due to habitat loss and fragmentation, the parrots are now restricted to specific areas. The population in Singapore was believed to have gone extinct by the 1950s due to habitat loss, although there have been occasional sightings in recent years.

On the other hand, the species was not recorded in Cambodia in the early 2000s, but recent surveys have found small populations in the country. These populations are believed to originate from birds that were illegally captured from neighboring countries and released into the wild.

The Blue-rumped Parrot’s distribution range has also changed due to human activities such as logging and deforestation. The parrots are now mostly confined to degraded and secondary forests, as they require large trees for breeding and feeding.

Habitat fragmentation caused by human activities is a significant threat to the species, as it reduces the availability of appropriate breeding and feeding sites. In conclusion, the Blue-rumped Parrot has undergone several changes in its systematics history, with the species initially classified as a subspecies of the Blossom-headed Parakeet.

The species displays geographical variation in both plumage and size, and two subspecies are recognized: P. cyanurus cyanurus and P.

cyanurus abbotti. Changes to the species distribution are also evident, with habitat loss and fragmentation affecting its current range.

The Blue-rumped Parrot is now mostly confined to degraded and secondary forests and remains subject to ongoing conservation efforts to ensure it’s long term survival.

Habitat

The Blue-rumped Parrot can be found in a range of habitats throughout its distribution range, from lowland rainforests to forest edges, plantations, and secondary growth. They prefer large, mature trees, as they require tree cavities for nesting and feeding.

The parrots are typically found at elevations of 300 to 2,000 meters, but they can also be found at lower elevations in certain parts of their range. The species is widely distributed in Southeast Asia, ranging from Myanmar in the west to Indonesia in the east.

In Malaysia, they are typically found on the west coast of the peninsular region, as well as on the islands of Penang and Langkawi.

Movements and Migration

Blue-rumped Parrots are generally non-migratory, although there have been reports of some limited movements in search of food and nesting sites. The species is known to be territorial, with breeding pairs occupying small territories.

During the breeding season, which occurs from March to July in Malaysia, they may be seen flying to and from their nesting sites, which are typically found in tree cavities. After the breeding season, the parrots may disperse to other areas in search of food and water but generally stay within their home range.

In areas with seasonal fruiting trees, the parrots may move between different areas to take advantage of different food sources. For example, in Malaysia, the parrots are known to move between lowland forests and higher elevation montane forests to take advantage of different fruiting seasons.

Conservation

The Blue-rumped Parrot is classified as Near Threatened by the International Union for

Conservation of Nature (IUCN). The species has undergone a significant decline in its population due to habitat loss and fragmentation caused by human activities such as logging, deforestation, and agricultural development.

Additionally, the parrots are often captured for the pet trade, which further impacts wild population numbers.

Conservation efforts to protect the species include habitat conservation and restoration, controlling illegal wildlife trade, and raising awareness about the importance of protecting the species. In Malaysia, the species is listed under the Wildlife

Conservation Act 2010, which provides legal protection against hunting, capture, or harming of the parrots or their habitat.

Additionally, some areas in Malaysia and other countries have established protected areas to conserve the parrots and their habitat. For example, the Royal Belum State Park in Malaysia is an important site for Blue-rumped Parrot conservation, as it contains large areas of primary forest and supports a healthy population of the species.

Conservation efforts at the park include habitat management and monitoring of the parrots’ population, as well as educating the public about the importance of the species. In conclusion, the Blue-rumped Parrot is found in a range of habitats throughout Southeast Asia and is non-migratory.

Although they may move within their home range to find food or nesting sites, they are generally territorial and do not undergo long-distance migrations. The species faces threats from habitat loss and fragmentation due to human activities, as well as capture for the pet trade.

However, conservation efforts such as habitat conservation and restoration, controlling illegal wildlife trade, and raising awareness about the importance of protecting the species are helping to protect the population.

Diet and Foraging

Feeding

The Blue-rumped Parrot is an omnivorous species, feeding on a variety of fruits, seeds, flowers, and insects. They have been observed feeding on a range of fruits, including figs, berries, and mangoes.

They have also been known to consume seeds from different tree species, as well as flowers and nectar. Insects, such as grasshoppers and beetles, make up a small part of their diet.

Diet

The parrots’ diet can vary according to the availability of food in their environment. During the breeding season, they tend to eat more fruits and seeds, as these provide the necessary nutrients for breeding and raising young.

In contrast, during the non-breeding season, the parrots may supplement their diet with more insects and other protein sources.

Metabolism and Temperature Regulation

Like many birds, the Blue-rumped Parrot has a high metabolism and needs to eat regularly to maintain energy levels. They maintain their body temperature by regulating blood flow to their internal organs and feathers.

By changing the volume of blood flow, they can regulate their body temperature more effectively. The parrots are adapted to the warm, humid climate of Southeast Asia.

They have a cryptic coloration that allows them to blend into their environment to avoid predation. Additionally, they have a respiratory system that allows them to conserve water by reabsorbing moisture from the air during exhalation.

Sounds and Vocal Behavior

Vocalization

Blue-rumped Parrots are a vocal species and use a range of calls and sounds for different purposes. They have a distinctive, high-pitched call, which is used for communication between individuals.

They also have a range of other calls, including contact calls, alarm calls, and threat calls. During the breeding season, male Blue-rumped Parrots use a unique vocalization to attract mates.

They perform a “chatter” call while bowing and raising their wings, which is thought to be an important component of their courtship behavior. The parrots also have a range of social calls, which are used for communication within their group.

Social calls include calls made during feeding or when flying between trees. The parrots also have contact calls, which are used to keep track of the flock and to locate other flock members.

In conclusion, the Blue-rumped Parrot is an omnivorous species that feeds on a range of fruits, seeds, flowers, and insects. Their diet can vary according to the availability of food in their environment and changes throughout the year.

The parrots have a high metabolism and need to eat frequently to maintain energy levels. Additionally, they use a range of vocalizations for communication, including distinctive high-pitched calls, courtship calls, and social calls.

The calls are an important component of their behavior and allow them to communicate with individuals within their group effectively.

Behavior

Locomotion

Blue-rumped Parrots are highly arboreal and spend most of their time perched in trees. They move around by hopping and climbing branches, and are capable of awkward, but effective flight over short distances.

Self-Maintenance

Like many bird species, the Blue-rumped Parrot spends a lot of time preening and grooming its feathers. They use their beaks to remove dirt and maintain feather structure, which helps protect them from the elements.

The parrots also use specialized glands to preen their feathers with oil, which helps to keep them flexible and water-resistant.

Agonistic Behavior

Blue-rumped Parrots are a generally non-aggressive species, but they will defend their territory against other birds. During breeding season, males may display aggression towards other males who enter their territory.

Agonistic behavior may include posturing, bill jabbing, and calling.

Sexual Behavior

Blue-rumped Parrots are monogamous and form breeding pairs that remain together for many years. During the breeding season, males will perform courtship displays to attract mates.

The courtship display includes bowing with ruffled feathers and high-pitched calls. Once the pair has bonded, they will mate and begin nesting.

Breeding

The Blue-rumped Parrot breeds during the wet season, which varies in different parts of their range. In Malaysia, the breeding season occurs from March to July.

The birds nest in tree cavities, usually located high above the ground. Both males and females participate in nest building, which consists of excavating a cavity in a dead or living tree.

Once the cavity is formed, the female lays 2-3 eggs, which she incubates for around 26 days. Both parents share the responsibility of feeding and caring for the young.

After hatching, the chicks are dependent on their parents for several months. During this time, they are progressively weaned onto solid food and begin to develop their flight feathers.

Once they have fledged, the young will remain with their parents for a period of time, during which they learn survival skills and gain independence.

Demography and Populations

The Blue-rumped Parrot faces several threats to its populations, including habitat loss and fragmentation, as well as capture for the pet trade. The parrots’ range has been significantly impacted by deforestation and land conversion for agriculture and urbanization.

Additionally, their population numbers may be impacted by the illegal pet trade, although data on this is limited. The species demography varies across its range, with some populations remaining stable while others are in decline.

In certain areas, such as Malaysia, the population is thought to have declined due to habitat loss and fragmentation, although some populations remain in protected areas.

Conservation efforts to protect the species include habitat conservation and restoration, controlling illegal wildlife trade, and raising awareness about the importance of protecting the species. These efforts aim to protect the Blue-rumped Parrot and ensure its long-term survival.

In conclusion, the Blue-rumped Parrot’s behavior includes highly arboreal locomotion, self-maintenance through preening and grooming, and a relatively non-aggressive agonistic behavior under most circumstances. The species is monogamous, with males performing specific courtship displays to attract mates.

During the breeding season, the species nests in tree cavities, with both parents participating in nest building and chick rearing tasks. Additionally, the parrots face several threats to their populations, including habitat loss, fragmentation, and capture for the pet trade, with conservation efforts aiming to protect the Blue-rumped Parrot and ensure its survival.

In conclusion, the Blue-rumped Parrot is a unique and distinctive bird species with a beautiful and colorful appearance. The parrots are widely distributed throughout Southeast Asia but face several threats to their population, including habitat loss and fragmentation, and capture for the pet trade.

Habitat conservation and restoration efforts, controlling illegal wildlife trade, and raising awareness about the importance of protecting the species are crucial to the Blue-rumped Parrot’s survival. The species’ behavior includes monogamous breeding pairs, highly arboreal locomotion, self-maintenance through preening and grooming, and a relatively non-aggressive agonistic behavior.
