We've had a blackcap singing in the park over the road for a couple of weeks now, and another one a few hundred metres away. Usually only get one for a couple of days on passage, as we also seem to with chiffchaff and willow warbler, both of which passed through very quickly a few weeks ago.
Elsewhere, have caught up with quite a few summer visitors, and have twitched green-winged teal locally, my first ever citrine wagtail (stunning male) in the Brecon Beacons, and 3 dotterel a few mins from M4 J26 last Monday (they've gone now).
