The Asian fairy bluebird is a small, colorful songbird found in forests and woodlands across tropical southern Asia. With its bright blue wings and long tail feathers, the male Asian fairy bluebird is a beautiful sight to behold. Though not well-known, this striking bird has some fascinating facts about its appearance, habitat, diet, breeding habits, and more. Read on to learn some fun and interesting tidbits about this lesser-known member of the Oriolidae family of birds!
Appearance
The Asian fairy bluebird gets its name from the gorgeous plumage of the male. Here are some key facts about the appearance of this vividly-colored bird:
- Males have deep, iridescent blue wings, back, and tail. Their heads are black, while their underparts are brownish-orange. Females are duller, with greenish upperparts and paler underparts.
- Their long tails can make up around 50% of their total body length. The tail feathers are used for display and balance while perched.
- Asian fairy bluebirds have thin, slightly curved beaks perfect for eating fruits and insects.
- They measure between 15–17 cm long from beak to tail tip. Their wingspans are around 23–26 cm wide.
- Weighing about 28 grams on average, they are similar in size to sparrows.
- The eyes are reddish-brown with an orange eye-ring around them.
- Legs and feet are orange-pink in color.
The male’s vibrant plumage likely helps attract mates and defend territories. Meanwhile, the duller female blends in better while incubating eggs.
Habitat
Asian fairy bluebirds occupy a specific type of forest habitat across their wide distribution. Here are key facts about where they live:
- They are found from India and Sri Lanka east through Southeast Asia to Indonesia and the Philippines.
- They inhabit the understory and middle levels of tropical evergreen and deciduous forests, woodlands, second growth, parks, and gardens.
- Favor areas with good canopy cover and dense patches of bamboo and vine tangles.
- Occur up to elevations of 1200 m in the Himalayan foothills.
- Can adapt to some human disturbance and degraded forest habitats.
Within their forest homes, fairy bluebirds prefer thicker vegetation close to the ground, which provides safety, insects to eat, and support for building nests.
Diet
The diet of the Asian fairy bluebird consists mainly of fruits and arthropods. Here are some key facts about what these colorful birds eat:
- Up to 70% of their diet can be fruit such as figs, berries, and small melons.
- Also eat a wide variety of insects like beetles, caterpillars, crickets, cicadas, and more.
- Will occasionally eat flowers, nectar, seeds, lizards, and geckos.
- Forage primarily in the dense understory vegetation, gleaning prey from leaves and branches.
- Sometimes sally out from perches to snatch insects from the air.
- Males and females cooperate to defend fruiting trees from other hungry birds.
Their diverse diet provides the energy and nutrients they need to maintain their active lifestyles. The fruits complement the high-protein arthropod prey.
Breeding and Nesting
One of the most interesting aspects of the Asian fairy bluebird is its unique breeding behavior and nest construction. Fun facts include:
- Breeding season is February to September, varying locally.
- Males perform courtship flights and sing to attract mates.
- They are socially monogamous, with pairs staying together for a whole breeding season.
- Both sexes cooperate to build an unusual pendant-shaped nest from vines, leaves, moss, bark, and spiderwebs.
- Nests have a tubular entrance dangling below, leading to a chamber above.
- They nest low down in dense thickets, hanging nests from slim branches.
- Clutch size is just 1-2 eggs, which are pale bluish-green with reddish spots.
- Incubation lasts 14-15 days. Both parents incubate eggs and feed nestlings.
- Chicks fledge at 17-19 days old but remain dependent on parents for a few more weeks.
The intricate hanging nests likely help protect eggs and chicks from predators. Both parents are involved in raising the young.
Threats and Conservation Status
Despite its wide distribution, the Asian fairy bluebird does face some threats to its long-term survival:
- Their forest habitats are being degraded and fragmented by logging, development, and conversion to agriculture.
- Climate change may alter fruiting cycles and arthropod populations they depend on.
- They are sometimes trapped for the pet trade, though less so than related species.
However, overall populations seem stable. The IUCN Red List categorizes the Asian fairy bluebird as a species of Least Concern. Protecting their forest habitat is the main conservation priority.
Fun Facts Summary
In summary, here are some of the most fun and illuminating facts about the dazzling Asian fairy bluebird:
- Males have iridescent blue plumage while females are dull greenish.
- They have very long tail feathers used for display and balance.
- Build unusual hanging pouch nests in dense thickets.
- Lay only 1-2 eggs at a time.
- Eat a diverse diet of fruits and insects.
- Found in forests from India to the Philippines.
- Not globally threatened but depend on habitat preservation.
