One at Llandilo this morning, first detected by its distinctive call high up in the oak canopy. It took a while to get a glimpse of it, because it was initially very flighty and was constantly on the move being harassed by a coal tit which seemed annoyed at its presence, or its call. After a minute or so they decided to ignore each other and were feeding a few feet away quite happily, though in silence. The yellow-browed stayed in loose association with a mixed group of tits and goldcrests for at least the next half-hour.
