The Blue-naped Pitta is a striking bird species that belongs to the family Pittidae. Known for its beautiful appearance and melodious call, this species is a favorite among bird enthusiasts.

In this article, well explore the identification, plumages, and molts of the Blue-naped Pitta.

Identification

Field Identification

The Blue-naped Pitta is a medium-sized bird that measures approximately 18cm in length and weighs about 40g. This species features a blue nape, black loral stripe, green mantle, wings, and tail, yellow underparts, and red vent.

Males and females are sexually dimorphic, with females featuring a duller plumage compared to males.

Similar Species

The Blue-naped Pitta can be confused with other species that share similar features. The Orange-breasted and Elegant Pittas, for example, feature similar blue and green plumages, but lack the blue nape of the Blue-naped Pitta.

On the other hand, the Rusty-naped Pitta features a rust-colored nape, while the Blue-rumped and Hooded Pittas feature blue rumps and hoods, respectively.

Plumages

The Blue-naped Pitta features three main plumages, namely the juvenile, non-breeding, and breeding plumages. Juvenile Plumage: Juvenile Blue-naped Pittas feature a duller and browner plumage compared to adults.

The blue and green feathers are yet to develop, and the bird may also lack the red vent. Non-

Breeding Plumage: This plumage is seen outside of the breeding season and is characterized by a duller coloration of the blue and green feathers.

The blue nape, however, remains strikingly visible.

Breeding Plumage: The breeding plumage is the most distinctive and striking. The blue and green feathers are at their brightest, and the red vent is also prominent.

Molts

The Blue-naped Pitta undergoes two molts each year, namely the pre-basic and pre-alternate molts. Pre-basic molt: This molt occurs after the breeding season, typically between July and December.

During this molt, the bird sheds its feathers and grows new ones to prepare for the harsher winter conditions. The old feathers are replaced by new ones with fresh colors and patterns.

Pre-alternate molt: This molt occurs in preparation for the breeding season and is seen between December and May. During this molt, the bird sheds its feathers again and grows new ones that are brighter and more striking, particularly in males.

Conclusion

The Blue-naped Pitta is a beautiful bird species that can be easily identified by its blue nape and bright plumage. Although it may be confused with other species, it remains a favorite among bird enthusiasts due to its striking appearance and melodious call.

Habitat

The Blue-naped Pitta is a forest bird that occurs in a wide variety of habitats across Southeast Asia, primarily in countries such as Thailand, Malaysia, Indonesia, and the Philippines. The species occupies a range of natural and anthropogenic environments, including primary and secondary forests, forests near waterways, and human-modified habitats such as plantations, gardens, and parks.

In the Philippines, the Blue-naped Pitta occurs in lowland and hill forests, forest edges, and in secondary growths. The species has also adapted to human-modified habitats, occurring in orchards, gardens, and even urban parks.

In Malaysia, the Blue-naped Pitta is found in both lowland and montane forests, as well as in human-modified habitats such as agricultural lands, plantations, and even suburban gardens. In Thailand, the Blue-naped Pitta primarily occurs in evergreen forests and mixed deciduous forests, as well as secondary forests adjacent to agricultural lands and human settlements.

The species is also found in gardens, plantations, and roadside habitats.

Movements and Migration

The Blue-naped Pitta is primarily non-migratory, with most populations remaining within their breeding range year-round. However, some populations in the northern areas of their range, such as Nepal, may undertake altitudinal movements in response to changes in climate and habitat availability.

In some areas, particularly the Philippines, rainforest fragmentation has resulted in populations that are confined to isolated forest patches. This has led to genetic isolation and reduced gene flow between populations.

As a result, the Blue-naped Pitta population structure in the Philippines is likely to be less homogeneous than in other areas where the species occurs. Some studies have suggested that the Blue-naped Pitta may exhibit nomadic behavior, moving between areas in response to changes in food availability and other ecological factors.

This behavior may be particularly common in areas that experience extreme weather or other disturbances that affect the availability of food or water. Understanding the movements and migration patterns of the Blue-naped Pitta is important for developing effective conservation strategies.

Habitat fragmentation and destruction can limit the species’ movements and lead to genetic isolation. In areas where the species is trapped in isolated forest patches, it may be necessary to establish habitat corridors to connect populations and facilitate gene flow.

In human-modified habitats, conservation efforts should focus on maintaining critical resources such as food, water, and shelter. In these areas, planting native trees and maintaining understory vegetation can provide habitat for the species and increase its chances of survival.

Conclusion

The Blue-naped Pitta is a forest bird that occurs in a range of habitats across Southeast Asia. Although primarily non-migratory, some populations may undertake altitudinal movements in response to changes in climate or habitat availability.

Habitat fragmentation and destruction can limit the species’ movements and lead to genetic isolation, making it important to establish habitat corridors to connect populations and facilitate gene flow. In human-modified habitats, conservation efforts should focus on maintaining critical resources such as food, water, and shelter to ensure the species’ survival.
