[edit] Taxonomy

Four subspecies accepted which are sometimes split in up to three species:

  • A. i. iouschistos (Rufous-fronted Tit)
  • A. i. bonvaloti and A. i. obscuratus (Black-browed Tit or Black-headed Tit or Bonvalot's Tit)
  • A. sharpei from Mount Victoria (Burmese Tit or Myanmar Tit)

The three forms seem to be morphologically distinct and form a superspecies with White-throated Tit. No evidence of intergradiation or hybridization where ranges meet.

[edit] Habitat

Boreal forests and temperate forests, especially rhododendron zone and low scrubby deciduous trees.

[edit] Behaviour

Outside the breeding season found in flocks of 10 to 40 birds, foraging through all heights of forest.
Resident with some altitudinal movement in winter.

[edit] Diet

Feeds on insects, larvae, sometimes on vegetable matter.

[edit] Breeding

Breeds from April to July. The nest is a ball made of lichens and lined with feathers.
