Greenish Warbler at Porth Joke and status in Cornwall

Greenish Warbler is a rare vagrant in Cornwall with just eight records up to June 2019. The two  records in 2019 are the first in Spring in Cornwall.  The species breeds in north and eastern Europe and Russia and has expanded its breeding range westwards during the last century. Migrates south east to winter in S. Asia.

1984: Nanquidno, 30th Sep to 1st Oct. Found by Dave Flumm. Paul Semmens, Lawrie Williams, Stuart Hutchings and Graham Hearl were also named as co-finders. It was present for two days and preferred the high canopy of the sycamore tree by the farmhouse with blue windows. It was also seen in the copse by the ford. This individual was by no means an easy ID and several observers of the day considered this to be a Two-barred Greenish.

2000: Kenidjack, 24th Sep. Found by John Swann and T. Whiley. This bird again spent much of the time in the high canopy in the copse part way down the valley.

2008: Pendeen, 16th to 17th Sep. Found by John Foster. This individual was found in the copse around Calartha Farm on the road down to Pendeen Watch. It was highly active and elusive at times. It was occasionally seen in the gardens adjacent to the copse.

2009: Church Cove, Lizard. 28th Oct to 1st Nov. Found by visiting birder Duncan Poyser from Cambs. Initially found at the bottom of the valley near Mariner's Cottage. The bird was highly mobile and could be found in the sycamores and elms in the churchyard as well as the copse at the bottom of the valley. This individual will be long-remembered for its see-saw identification between Green and Greenish. Eventually confirmed by sonogram on the call by Magnus Robb, Ilya Maclean and Hugh Harrop.

2010: Treeve Common, Land's End. 25th-29th Sep. Found by John Chapple.

2016: Porthgwarra, 24th August, M Elliott, J F Ryan.

2017: Millbrook, St Andrew's Street. 23rd-25th Aug.

2019: Lizard Village. 4th June. One seen briefly by Tony Blunden.

2019: Porth Joke, Crantock. 9th June. Singing male in willows below Treago campsite, found by Steve Rowe.

Black-headed Wagtail at the Lizard

An adult male Black-headed Wagtail was found at the Waterings, Housel Bay, Lizard on Sunday 19th May by Tony Blunden.  It spent all day in the cattle field catching insects.  The record followed a strong easterly air flow directly from Scandinavia.  It was present for just one day.

I have seen a lot of this sub species of Yellow Wagtail abroad in Cyprus, and this bird is one of the purest I have seen.  There was no white in the chin or hint of any supercilium.

A look at past Cornwall records makes this bird the third record.  Several previous records have been rejected on review or just not submitted, see below data kindly supplied by Derek Julian.
