With its vibrant blue and orange feathers and distinctive call, the Blue Pitta, or Hydrornis cyaneus, is a bird that is sure to catch the eye and ear of birdwatchers and nature enthusiasts. This species can be found across Southeast Asia, and is a favourite among birders due to its striking appearance and elusiveness.

In this article, we will explore the identifying features of the Blue Pitta, as well as its habitat, breeding habits, and preferred diet, so you can be sure to spot one on your next birdwatching adventure.

Identification

Field Identification

The Blue Pitta is a stocky bird with a robust bill and longish tail. It stands about 17cm tall and weighs about 50 to 80 grams.

Adult males have vibrant blue feathers on their back, crown, and wings, while their face, throat, and underparts are a rich orange hue. Females, on the other hand, have more muted colours, with olive-brown feathers on their back and wings, and a chestnut-brown underside.

Their head and throat are also brown, and they have a paler belly. Juvenile birds resemble females but are duller and less colourful overall.

When spotting a Blue Pitta in the wild, it is important to look for its distinctive call, which is a loud, metallic, and slightly nasal “chet chet chet”. They are often heard before they are seen, as they are generally secretive and wary birds that prefer to stay hidden in dense vegetation.

Similar Species

The Blue Pitta can be easily mistaken for other similarly coloured species, such as the Blue-winged Pitta, however, there are subtle differences that set them apart. The Blue-winged Pitta has a blue back, but with a greenish tint, and a white belly.

Its face and throat are black, and it has a prominent white stripe above its eye. The call of the Blue-winged Pitta is also different, sounding more like “piu piu piu”.

Plumages

The Blue Pitta undergoes a complete annual molt, during which it replaces all of its feathers. Juveniles and females go through a pre-basic molt between May and June, while adult males undergo a pre-alternate molt between December and February, just before the breeding season.

The molt is often triggered by changes in daylight and temperature, and is important for the bird’s survival, as it helps streamline its feathers for better insulation and aerodynamics.

Breeding

The breeding season of the Blue Pitta varies depending on location, typically occurring between April and August in Southeast Asia. During this time, the male Blue Pitta creates a nest in the forest understory, using materials like leaves, twigs, and moss.

He attracts a female with his call and displays, which involve fanning his wings and tail to show off his vibrant colours. Once they have paired up, the female lays a clutch of 3-4 eggs, which she incubates for around 15 days.

Once hatched, the chicks fledge after around 16-18 days, and are fed by both parents for a few more weeks before becoming independent.

Habitat and Distribution

The Blue Pitta is found across Southeast Asia, in countries like Thailand, Laos, Cambodia, Vietnam, Malaysia, and Indonesia. They are highly adaptable birds that can thrive in a range of habitats, including dense forests, bamboo groves, and even secondary growth areas.

They prefer areas with thick understory vegetation, and can be found at elevations up to around 1,500m.

Diet

The Blue Pitta is an omnivorous bird that feeds on a variety of insects, small mammals, and fruits. Their diet includes beetles, termites, snails, spiders, centipedes, and earthworms, as well as berries, figs, and other fruits.

They are often found foraging on the ground, using their bill to flick through leaves and debris to find their prey.

Conclusion

The Blue Pitta is a striking and elusive bird that is sure to delight any birdwatcher lucky enough to spot it in the wild. With its vibrant blue and orange feathers, it is a species that is both beautiful and fascinating.

By understanding its identifying features, habitat, breeding habits, and diet, you can increase your chances of observing and appreciating this magnificent bird on your next nature adventure.

Systematics History

The Blue Pitta, or Hydrornis cyaneus, is a member of the Aves class, order Passeriformes, family Pittidae. The species was first described by Temminck in 1822.

Since then, the taxonomic classification of the Blue Pitta has gone through several revisions, reflecting changes in our understanding of the bird’s morphology and genetics.

Geographic Variation

The Blue Pitta has a wide distribution across Southeast Asia and is found in a range of habitats. Despite this, there is limited variation in the morphology of the species across its range.

Subspecies

There are several recognized subspecies of the Blue Pitta, with subtle differences in plumage coloration and size. These subspecies are:

– H.c. cyaneus – found in southern Thailand and Peninsular Malaysia and has a bright blue crown and back, and deep orange underparts

– H.c. bangkokensis – found in central and western Thailand and has a slightly greener blue back and darker orange underparts than H.c. cyaneus

– H.c. sumatranus – found in Sumatra and has a darker blue back and a more russet-toned orange underparts than the other two subspecies

However, these subspecies are still subject to debate and further research is needed to determine their taxonomic validity.

Related Species

The Blue Pitta is part of the Pittidae family, which includes around 35 species of ground-dwelling, insectivorous birds. The family is primarily found in tropical regions of Asia and Oceania, and many species have bright, colorful plumage.

The Blue Pitta is closely related to the Giant Pitta (Pitta caerulea) and the Mangrove Pitta (Pitta megarhyncha), which also occur in Southeast Asia.

Historical Changes to Distribution

The Blue Pitta’s distribution has changed over time, reflecting the impacts of habitat destruction and climate change on the bird’s range. In earlier times, the species was found in a broader area, including the southwestern Yunnan Province and the island of Hainan in China, throughout much of the Indochinese Peninsula, and on Sumatra and Java.

However, historical records suggest that the Blue Pitta has experienced a significant decline in population and range since the 20th century. The decline is primarily attributed to habitat destruction and fragmentation caused by deforestation for agriculture, logging, and urbanization.

The species’ preferred habitat of dense undergrowth and forest floor is particularly vulnerable to human activity, and the fragmentation of forested areas has led to a decline in the size of the Blue Pitta’s habitat range. In addition to habitat loss, climate change is also having an impact on the Blue Pitta’s distribution.

As temperatures rise, suitable habitats for the species are shifting upwards in elevation, and the Blue Pitta is being forced to move to higher altitudes. This has led to a contraction of the species’ range, and it is now considered near threatened by the International Union for Conservation of Nature (IUCN).

Diet and Foraging

The Blue Pitta is a primarily insectivorous bird, feeding on a range of arthropods, including beetles, termites, spiders, snails, earthworms, and centipedes. The species occasionally consumes small mammals, reptiles, and amphibians, but these are not significant parts of their diet.

Feeding

The Blue Pitta is a terrestrial bird that forages mainly on the ground, using its strong legs and feet to scratch and hop amongst leaf litter and debris. They have a distinctive feeding behavior in which they flick their bills rapidly through the leaves and twigs to uncover hidden prey.

They are skilled at finding small invertebrates, and their long, curved bill allows them to extract insects from small crevices in the soil. The birds are also known to climb up into the vegetation to search for prey, particularly during the breeding season when they may need to find food to feed their chicks.

They are active feeders during the early morning and late afternoon, with feeding bouts lasting up to several hours.

Diet

The diet of the Blue Pitta varies depending on the bird’s location and the availability of prey. In Southeast Asia, the species feeds heavily on ants, beetles, and termites, with termites accounting for a significant portion of their diet.

The birds are also known to feed on ants’ eggs and pupae, which are high in nutrients. In areas with a higher prevalence of snails and other soft-bodied invertebrates, the Blue Pitta will include these in their diet.

In some locations, the birds have been observed feeding on small reptiles and amphibians or consuming fruits.

Metabolism and Temperature Regulation

The Blue Pitta has a unique metabolism and temperature regulation system that allows it to maintain high levels of energy and activity despite living in hot and humid environments. Studies have shown that the species has high amounts of adipose tissue, or fat, which provides energy reserves during times of low food availability.

The birds also have high levels of mitochondrial enzymes, which allow for efficient energy production. To regulate their body temperature, the Blue Pitta will pant, gape its bill, and hold its wings away from its body.

These behaviors help release heat from the body and increase evaporative cooling, allowing the birds to maintain a stable body temperature in hot and humid environments.

Sounds and Vocal

Behavior

Vocalization

The Blue Pitta is known for its distinctive vocalizations, which play a critical role in communication and territory defense. The birds produce a clear, metallic “chet-quet-quet” call that is often heard before the bird is seen.

The call is repeated quickly and can be heard over long distances. During the breeding season, males will also produce a variety of other calls and songs, often while perched on high vantage points like trees or rocks.

These calls and songs are used to attract mates and defend territory from other males. The male will display visually while singing, fanning out the feathers on his wings and tail to show off his bright blue coloration.

Females are less vocal than males, but they are known to produce a soft, whistling call when alarmed or communicating with chicks. Juveniles also produce a unique begging call to solicit food from their parents.

Conclusion

The Blue Pitta is a fascinating bird species that has adapted to life in dense forest habitats. The birds are skilled insectivores with unique foraging behaviors and feeding adaptations.

They also have a unique metabolism and temperature regulation system that allows them to maintain high activity levels despite living in hot and humid environments. The birds’ vocalizations are also notable, with a metallic, repeated call that is often the first sign of their presence.
