Black-casqued Hornbill

Tiny warbler with a long bill and frequently cocked tail. Secretive, tending to stick to the brushy underlayer of hill and submontane forest. Often moves about solitarily, but can sometimes be found with mixed-species flocks, especially with small warblers and fulvettas. Green above and yellow below, with a pale gray throat. Somewhat resembles a Common or Dark-necked tailorbird, but only a fraction of the size, with a proportionally far longer bill, black eye-stripe, and bright orange forehead. Song is an extremely high-pitched tinkling series of whistled notes with an otherworldly quality. Calls include high descending trills and dry chittering.

A medium-sized prion with a noticeable dark “M'' stretched across their back from wingtip to wingtip noticeable in flight. They breed on Antarctic and subantarctic islands in the South Indian, Southern and South Atlantic Oceans and are widespread and abundant at sea around these areas. Regular visitor to New Zealand and Southern Australia during the austral winter. Very similar to other prion species, especially Salvin’s prion, with the Antarctic prion having a slightly brighter blue bill with straighter sides and a larger nail at the tip.

Very similar to Common Nightingale, but more dusky brown (not reddish-brown), with a duller and darker rufous tail and a mottled brown (not plain and sandy) breast. Their songs can be confusingly similar, but Thrush Nightingale is more monotonous, less varied, and slower, resembling that of Song Thrush. Calls include a bright but difficult-to-locate “teek”, and a low, dry rattle. Breeds in thick, damp, deciduous forest as well as well-wooded parks and gardens. Winters in tangled, often damp, thickets and brushy vegetation. Turns up in a wide range of habitats on passage, including drier areas. Feeds on invertebrates and berries.
