Irenidae

Fairy Bluebird

The two fairy-bluebirds are small passerine bird species found in forests and plantations in tropical southern Asia and the Philippines. They are the sole members of the genus Irena and family Irenidae, and are related to the ioras and leafbirds. These are bulbul-like birds of open forest or thorn scrub, but whereas that group tends to be drab in colouration, fairy-bluebirds are sexually dimorphic, with the males being dark blue in plumage, and the females duller green.

Both species eat fruit, especially figs, and possibly some insects. They lay two to three eggs in a tree nest.

The call of the Asian fairy-bluebird is a liquid two note Glue-It.

As the names would suggest, the Asian fairy-bluebird occurs across southern Asia, and the Philippine fairy-bluebird in that archipelago. They are robust birds that resemble Old World orioles in shape and size. Males are larger than females, and the two species weigh between 50g & 100g, with some of that variation being caused by sexual differences and some by geographic variation. There are clines in size differences in both species which can be attributed to Bergmann's rule, with the northernmost populations being larger on average. Both species have a powerful deep and notched bill used for crushing, with that of the Philippine species being larger. Their feet are small, which suggests that they spend less time climbing in order to feed and more time on the wing.

Their plumage is exceptional, with the upper-parts being deep rich blue. The Asian fairy-bluebird is sexually dimorphic in its plumage, with the male being much brighter than the female, but the Philippine fairy-bluebird exhibits much less difference and the female is almost as bright as the male. The deep colour is provided by specialised naked feather-tip barbs. Although the fairy-bluebirds are highly visible in sunlight they are much less visible in the shade of the forest.

They have a discontinuous distribution from India to Java and Vietnam. In India the species is present in the south west of the country and in the north east. From Burma it has a continuous distribution (in suitable habitat) throughout most of South East Asia, and down into Borneo and Sumatra, as well as on the Andaman Islands. The species has not been reliably recorded on Sri Lanka since the 1870s. The Philippine fairy-bluebird is found only on Luzon, Polillo, Leyte, Samar, Mindanao, Dinagat and Basilan.

They are dependent upon fruit producing forests, but both species seem to exist in a wide range of forests, both evergreen and semi-evergreen where they forage widely to obtain food.. Within forests they are usually found in the canopy. They generally eat fruit of a certain size, and will crush larger fruits in order to make them manageable. Most food is obtained in the canopy. In addition to fruit berries may be eaten, as well as nectar, although this behaviour has only been reported in birds in India. In contrast to adults, however, insects are the principal component of the diet of nestlings. In the Philippines birds have been observed following troops of macaques, possibly in order to collect flushed insects.

Male courtship displays include elaborate vocalisations, which the female responds to with nest building. Nests are constructed in trees or tall bushes from twigs, moss and grasses, and males and females cooperate in rearing chicks

There are just two species in this family of Fairy Bluebirds; they are:

Family Account

The Fairy-Bluebirds are a small group of arboreal passerines found throughout tropical Asia. There are but two species in the genus Irena. The widespread bird ranging from eastern India through SE Asia to Java and Palawan in the Philippines is the Asian Fairy-Bluebird (left and below right in fine shots from the Andaman Islands by Ron Saldino). The only other member of the family is the Philippine Fairy-Bluebird Irena cyanogaster, endemic to the major Philippine islands…

Species Account

The Asian fairy bluebird eats fruits, nectar and some insects. Its call is a liquid two note glue-it.

Asian Fairy-bluebird Irena puella

HBW Species Account

Taxonomy: Coracias Puella Latham, 1790, Travancore, southern Kerala, India. Formerly considered conspecific with I. cyanogastra. Race andamanica treated as synonymous with nominate by some authors, but differs in having heavier bill. Birds from N Indian Subcontinent, described as race sikkimensis, considered better treated within nominate. Body size varies with latitude, outer tropical populations of nominate being largest, equatorial crinigera smallest. Race tweeddalei has sometimes been spelt tweeddalii, following very slightly later usage by same author; latter, however, must be rejected as unjustified emendation or incorrect subsequent spelling. Six subspecies recognized.
