Heterophasia picaoides

Identification

28–34·5 cm (11-14 in), an unmistakable Sibia¹:

Grey to greyish-brown
Long, white wing patch
Extremely long, graduated, broadly white-tipped tail
Slender bill which is slightly downcurved
Dark, red eyes

Juveniles have grey eyes. Can be confused with Grey Treepie, Green-billed Malkoha or a Blue Magpie in flight.

Distribution

Found from the Himalayas (Central Nepal) east over Sikkim and Bhutan to NE India and NE Bangladesh to Myanmar, Thailand, S China (Yunnan, Guangxi) and Laos. Also south to Peninsular Malaysia and on Sumatra (Indonesia).
Very rare in Nepal but common in most other parts of its range.¹

Taxonomy

Subspecies

Usually four subspecies are recognized^{1, 2}:

H. p. picaoides from C Nepal east to Bhutan, NE India, N Myanmar, S China (Yunnan) and also NE Bangladesh
H. p. cana in Myanmar, Thailand, Laos, Vietnam and SE China (SE Yunnan to W Guangxi)
H. p. wrayi in Peninsular Malaysia
H. p. simillima on Sumatra

Cana is sometimes considered doubtfully valid.¹
If the genera Leioptila and Malacias would be accepted, this species would be the only remaining member of Heterophasia.¹

Habitat

Broadleaf evergreen forest, forest edge, secondary growth, open scrub with large trees, forest clearings. Usually found between 100m and 3000m. ¹

Behaviour

Diet

Feeds on insects, flower buds, fruits, berries and seeds. Also known to take nectar. Forages mostly in the canopy.
Seen in pairs or small groups of 4 - 15 birds, sometimes more. Often with other species in bird waves.

Breeding

Breeding season from February to August. The nest is a deep cup made of moss with dead leaves, placed on a horizontal branch or suspended from thin twigs of a tree, 6 - 9m above the ground.

Movements

Resident species, unconfirmed altitudinal movement reported.¹
