Reports of Pallid Swift have been in the news this week. The following write-up and original submission to BBRC serves as a timely reminder for anyone searching for Pallid Swifts over Cornwall, hopefully proving useful.
This record below was accepted by BBRC.
It was only a matter of time before a Pallid Swift would turn up in Cornwall this Autumn. With so many others dotted around the east and south coasts, one would surely end up in Cornwall. On Sunday 18th an early shout from Vicky Barnes went out of a swift seen flying over Rose Valley near Pendeen. Several birders searched the various nearby valleys and likely spots but without luck.At around midday, another report was sent in to Cornwall Birding of a swift around the Land's End complex. Luckily John Chapple had just arrived on site and connected pretty soon. With close views overhead, he was sure it was a Pallid Swift and put the news out. I called John, got some details and arrived ten minutes later. I also connected quickly as the bird hawked low over the moor to the north of the complex. In perfect light with the sun behind us, we could see the paleness of the bird and why its called a Pallid Swift. The dark inner axillaries/secondaries compared to an otherwise pale underwing was immediately noticeable, even at distance through my bins. Within an hour, some 20 more birders had seen it.
After a close look at the accepted records, this bird is the fourth record for the county and my first for Cornwall. The first record was at St Levan in November 2004. First noted as a swift sp, it was later accepted as a Pallid Swift in 2005 (CBWPS Report 2005). The second was at Wadebridge in June 2007. The third was found by Kester Wilson at Nanjizal in May 2009. There was another interesting swift in Nov 2016 found at Kenidjack and then Botallack/Pendeen, but it was eventually considered to be a Common Swift, possibly of the subspecies pekinensis, though the latter has yet to be accepted in the UK.
The images below were taken by myself. John Ryan has also taken a close interest in this bird and given me for comparison, three images of the 2016 Common Swift at Kenidjack. I have linked the photo's together for exact comparion. The differences are subtle:
Pallid is overall paler and browner with obvious dark inner secondaries
Pallid has a less defined throat patch
Pallid has no white supercilium/patch in front of the eye
Pallid has a slightly larger head with the impression of a large eye
Pallid has less clear white trailing edge to the secondaries.
Pallid has less white showing in the leading edge of the wing
