Chestnut-crowned Warbler (Phylloscopus castaniceps) is a small, active leaf warbler found in the forests of the Himalayas and Northeast India. It is easily recognised by its rich chestnut crown, bold yellow underparts, and distinctive white eye-ring. Usually seen in mixed-species flocks, it forages in the understorey and mid-canopy, flicking its wings and tail restlessly.

Red-throated Thrush (Turdus ruficollis) is a medium-sized thrush that breeds in Central Asia and during winters in South Asia, including parts of northern India. Males are distinguished by a rufous throat and breast, contrasting with greyish upperparts. This species is a rare winter visitor to the Indian subcontinent and is often seen foraging on the ground or in fruiting trees.

Crested Finchbill (Spizixos canifrons) is a distinctive bulbul of Northeast India, known for its prominent crest and olive-green plumage. It frequents forest edges, secondary growth, and gardens, often seen in noisy flocks feeding on fruits and insects. Its melodious calls and social behaviour make it easy to detect.

Chestnut-capped Babbler (Argya ruficeps) is a skulking, long-tailed babbler of tall grasslands and scrub in the Indian subcontinent. It is easily identified by its rich chestnut crown contrasting with white underparts and buffy flanks. Often heard before seen, it moves in pairs or small groups, weaving through dense vegetation with jerky movements and constant calls.
