I spotted these two preening lovebirds in the sunshine at the Mull today. They sat on the same rock, grooming and preening each other for hours. Apparently, it has been scientifically shown that the longer a pair of seabirds grooms each other for, the better their breeding success. This pair, uncharacteristically for guillemots, have set themselves apart from the rest of the colony. I don't blame them, a chance to spend some quality time away from the constant bickering, bill-fighting and noise of the guillemot ledge.
