The predawn thunk of a window collision reminds one that birds rise early. The collision was a consequence of birds flying to an adjacent rowan tree (European mountain ash).
Most of the birds flying to the rowan berries were robins.
However, a species not immediately recognized has tentatively been identified as a Hermit Thrush.
Also taking part, but spending most of its time preening, was a Yellow-rumped Warbler.
