Alpine Accentor
Prunella collaris
This is a robin-sized bird at 15–17.5 cm (5.9–6.9 in) in length, slightly larger than its relative, the dunnock. It has a streaked brown back, somewhat resembling a house sparrow, but adults have an all-grey head and red-brown spotting on the underparts. It has an insectivore's fine pointed bill. Sexes are similar, although the male may be contrasted in appearance. Young birds have browner heads and underparts.

Dunnock
Prunella modularis
A robin-sized bird, the dunnock typically measures 13–14.5 cm (5.1–5.7 in) in length. It has a brown back streaked blackish, somewhat resembling a small house sparrow. Like that species, the dunnock has a drab appearance which may have evolved as camouflage to avoid predation. It is brownish underneath, and has a fine pointed bill. Adults have a dull grey head, and both sexes are similarly coloured; juveniles are browner on the head, looser, 'fluffy' feathering, and more obviously streaked overall.
