Bonaparte’s Gull – 2018

Chroicocephalus philadelphiaGwylan Bonaparte – Vagrant

One at the Gann, 4th and 5th November

As Mr Astins thought it may be possible to see the Swift from the main land. I went to St Anne’s he went to Martins Haven. On my way back having had very horrible views of Skokholm in the poor visibility, I thought I would scan the gulls on the Gann. Picked out a Bonaparte’s gull in with the gulls opposite Crab Hall. As always wanted, confirmation from someone, so met up with DA at Martins Haven, where I showed him photos and video. He Confirmed it. Posted by Peter Howe at 5:40 pm

Then about 4.20pm I picked the bird up in a small roost forming maybe 150m offshore.  Too far for any decent photographs, but my poor efforts show some of the key features – smaller size, darker, dark bill & grey shawl along the neck sides.  I was also able to see the pale under primaries whilst it preened, and when the whole flock flew further out to sea the more buoyant flight with faster wingbeats were quite obvious.  This is only Pembrokeshire’s 4th Bonaparte’s, after birds at Solva in Spring 1888, and Strumble Head on 28th September 1997 and 16th-20th October 2012.  Be nice if it stays around.
