Possible Black-bellied Dipper in Dublin

Found the day of the arrival of The Beast from the East, this unusually dark-bellied dipper has been hanging around the same spot on the river Dodder in the middle of Dublin. If it is a Black-bellied Dipper it has been pushed across from continental Europe, the closest area that is occurs is probably Denmark.

The Irish race of Dipper, ssp. Cinclus cinclus hibernicus has a narrower chestnut breast band than the British race (C. c. gularis). This bird has a few chestnut feathers only.

Wherever it comes from, this bird shows no signs of homesickness, and seems to be collecting nesting material in preparation for a long stay...
