Eurasian wren
Adult birds are about and the sexes are similar in this species. As compared to the Eurasian wren ("Troglodytes troglodytes"), it is much darker in colouration, especially the crown and nape which are nearly black. The barring on the upper parts is blacker and the markings on the lores and ear coverts are darker brown. The throat and breast are brownish-buff rather than white and the dark speckling on the belly extends further up the flanks and breast. The beak is dark brown and the sturdy legs are mid-brown. The song is rather louder and more varied than the Eurasian wren, perhaps to make it more audible on the boulder beaches where it mainly breeds.
