Strong SW winds continue. Handful of Curlew, Swifts & a solitary House Martin went south. Family party of Swallows have been loitering on site the last few days that have obviously been reared not to far away. At mid-day the Serin showed up again. If you haven't seen it yet then it is elusive & if you want to see it then be prepared to put the time in - one thing it does seen to be is very vocal when it is in flight so wash your ears out and listen for that little trill (but be beware of all the baby birds around at the moment doing some weird & wonderful calls sometimes resembling it !).
