Appearance:

Very deep and heavy, conical bill. Large head and bull-neck, gives the bird a front-heavy appearance, especially in flight. The short tail adds to the impression. Wings with broad, white bars and tail with white terminal band. Bill grey in breeding plumage, and yellowish in winter. Largely unmistakable, but easily overlooked when hiding high in foliage. Often flies high, even for short distances. Flight heavily undulated.

Sound:

Most typical call a sharp and explosive "tzek", with abrupt, emphasized, cut-off ending. Quite similar to Robin, but harder, with each syllable marginally longer with a slightly wheezing timbre. Repetitions are slower and more singular than Robin. Diagnostic when interspersed with high frequency notes.
