Foraging

Fruits and insects, but like its cousin of the plains it also destroys large numbers of eggs and nest-young of small birds. It is likewise very fond of flower nectar; Silk Cotton and Rhododendron blossoms are regularly visited in season.D

Biology And Ecology

Throughout its Himalayan range this Tree Pie breeds at elevations between two and five thousand feet, and sometimes up to seven thousand feet. April to July are the months most favoured.E

Nest

The nest is of the crow type, a flimsy platform of thin twigs, coarse roots, tendrils, etc. The shallow depression for eggs in the centre is lined with finer material. It is usually built between eight and twenty feet up on saplings growing in forest or in the neighbourhood of scrub-covered ravines.E

Egg

The eggs - three to five - range from pale bluish or yellowish-stone colour to rich yellowish cream. They are boldly blotched with dark or reddish-brown, more numrously at the broad end. The texture is fine and glossy.E

Behaviour

They go about in pairs or parties which keep up a noisy conservation in harsh, rather metallic notes. The flight is undulating, consisting of a few rapid flaps followed by a short glide. Especially when flying from one treetop to another the birds seem to rocket down in a curious way at a steepish angle on each undulation.E

Ectoparasite

Philopterus emersoni R.D. Price & Hellenthal, 1998F

Voice

Some of the calls are quite melodious.E
