Blue-crowned Hanging Parrot (Loriculus galgulus)

The Blue-crowned Hanging Parrot (Loriculus galgulus) is a small, vibrant parrot species known for its unique ability to sleep upside down, much like bats. Found primarily in Southeast Asia, this species is a rare visitor to the Sundarban region, preferring dense tropical forests and mangrove ecosystems. Its striking blue crown, green body, and red undertail make it one of the most colorful birds in its habitat.

Taxonomy and Classification

• Kingdom: Animalia
• Phylum: Chordata
• Class: Aves
• Order: Psittaciformes
• Family: Psittaculidae
• Genus: Loriculus
• Species: Loriculus galgulus

The Blue-crowned Hanging Parrot belongs to the genus Loriculus, commonly known as hanging parrots, named after their peculiar sleeping posture.

Morphology and Physical Characteristics

• Size: Small parrot, measuring around 12–14 cm (4.7–5.5 in) in length.
• Weight: Approximately 28–36 grams.
• Plumage:
  • Bright green body, providing excellent camouflage in foliage.
  • Blue patch on the crown, which gives the species its name.
  • Red rump and undertail, adding a splash of color during flight.
• Sexual Dimorphism:
  • Males have a more prominent blue crown.
  • Females generally lack the intense blue markings on the head.
• Juveniles:
  • Similar to females but with duller coloration and less distinct crown markings.

Habitat and Distribution

The Blue-crowned Hanging Parrot is native to Southeast Asia, including:

• Malaysia, Thailand, Indonesia, Myanmar, Vietnam, and the Philippines.
• It inhabits lowland forests, mangroves, and plantations, preferring areas with dense tree canopies.

Presence in Sundarban

While the Sundarban mangrove forests do not provide an ideal primary habitat for this species, occasional sightings have been recorded in:

• Fringes of the Sundarban Biosphere Reserve, where semi-evergreen and moist deciduous forests exist.
• Coastal forest patches and riverbanks, where they may be seen foraging.

The species is more common in Southeast Asian mangrove forests, but due to its highly mobile and nomadic nature, some individuals may appear in the Sundarban as transient visitors.

Diet and Feeding Behavior

The Blue-crowned Hanging Parrot is a frugivore and nectarivore, feeding on:

• Soft fruits (figs, bananas, papayas, guavas).
• Nectar from flowers (important for pollination).
• Tree sap and young buds.
• Occasionally, insects and larvae for protein intake.

Its small size and agile flight allow it to feed among high tree canopies, where it blends seamlessly with foliage.

Special Features and Behavior

• Hanging Sleepers: Unlike most parrots, these birds sleep upside down, similar to bats.
• Silent Flyers: Their small size and swift movement make them difficult to spot.
• Non-aggressive Nature: They are generally shy and prefer staying within dense foliage.
• Breeding Season: Occurs between March and June, with nests built inside tree cavities or old woodpecker holes.

Conservation Status

• Classified as Least Concern (LC) by the IUCN Red List.
• Major threats include deforestation, habitat loss, and illegal pet trade.
• Protection measures in mangrove reserves and tropical forest sanctuaries help conserve their populations.

The Blue-crowned Hanging Parrot is an extraordinary small parrot species, known for its unusual roosting habits and striking plumage. Though rarely sighted in the Sundarban, occasional records indicate that some individuals may pass through coastal forest patches in the region. For birdwatchers and nature lovers, a Sundarban private tour package offers an excellent opportunity to explore the diverse avifauna of the Sundarban Biosphere Reserve.
