The last two weeks has seen unsettled weather with temperatures ranging from 17 degrees to as low as 7 degrees. Wind direction has varied from south easterly to north westerly and has been gale force at times. Birders always keep a close eye on the weather as it influences what can potentially be found.
Spring migration peaks in mid May and thereafter falls away quickly. The period has produced a good number of rarities though many have been seen by single observers only. New discoveries all have a distinct Mediterranean flavour and have included an adult Purple Heron near Probus, White Stork at Tregoss, Kentish Plover at Sennen Beach, flyover Bee Eaters at St Levan, Red-rumped Swallow at Marazion Marsh, Alpine Swift and Red-throated Pipit at Pendeen, several Serins, five Woodchat Shrikes and perhaps up to ten Hoopoes this Spring. In terms of national status, Montagu's Harrier, the rarest of all UK breeding raptors, a juvenile (ringtail) was seen at Coombe on 14th May.
Wader passage has been light compared to past years but fair numbers of Sanderlings, Dunlins, Ringed Plovers and Turnstones have been seen at typical coastal sites. Purple Sandpipers have peaked at 42 birds at Battery Rocks, Penzance. Most of them are now in full summer breeding plumage. By June they will all be on territory in the high Arctic.
Away from Cornwall, an Eastern Subalpine Warbler and potential first record for Devon was found on Sunday at Dawlish Warren.
