Additions for 7th to 14th Dec – A serendipitous ‘first’ for Lundy: not one but THREE Great White Egrets!

This post includes additional records from Martin Thorne for the period 7th to 14th Dec and should be read together with the previous post, from Dean Jones, covering sightings for 4th to 19th Dec.
 
On discovering that the Radio Room was available for a week following a cancellation, Martin Thorne grabbed the opportunity for a pre-Christmas break on the island. Here’s his summary, including an encounter with not one but three Great White Egrets – a new species for Lundy’s burgeoning bird list!

“My week started with a skua harassing Kittiwakes off the Landing Bay on 7th. It looked very much like a juvenile Herring Gull but had the distinctive raised wings of a skua but with no noticeable wing barring – a shame I didn't have my 25x100 binoculars handy as I feel certain it was a Pomarine (certainly the most likely skua species to occur in SW waters this late in the year – eds). The following day a Mediterranean Gull off the Jetty was showing an interest in a Grey Mullet dying of a severe infestation of gill parasites (see photo). Later on I saw a Yellow-browed Warbler feeding around the gateway opposite the Shop. On Wednesday a white-winged gull flew over the Airfield, possibly a Glaucous though it looked rather small. Looking through the gulls again on Thursday, I picked out one or more adult Yellow-legged Gulls. On Saturday there were two immature Glaucous Gulls, one white, one very brown (see photo). I would say from the markings on its head the latter was the same bird that turned up on Monkstone Beach, Pembrokeshire, due north of Lundy, on 14th Dec (see https://pembsbirds.blogspot.com/). The same day I made it up to the North End. It was very quiet bird-wise, with six Snipe around Pondsbury and just three Gannets off North End. On Sunday I noted well in excess of 450 gulls, split into roughly four flocks.

On most days there were two or more Black Redstarts, four Stonechats and a Chiffchaff in Millcombe, a single Great Northern Diver off the East Side, and a Woodcock in and around St John's Valley at dusk. Standing outside the Radio Room at one point, a stone bounced off the roof and hit the ground hard. On closer inspection I realised it was a gastrolith, or gizzard stone, consisting of a piece of tarmac – no doubt purged by some high flying gull.

Undoubtedly the high point of my stay came on 8th when, from below the South Light, I saw what I first thought were three Cattle Egrets approaching from the west. As they loomed into view I became aware of their much larger size, brilliant white plumage, dark legs, yellow bill and rather heron-like cranked neck posture – three Great White Egrets (which I later learned from the two Tims were new for Lundy!). Without stopping, they headed away east toward the mainland. Oh, and I mustn’t forget also two speedy Teal at dusk!

Non-avian sightings included a superb stag Sika Deer in Middle Park, and a Grey Seal emerging from kelp and various bits of 'human' waste along the East Side."

Congratulations Martin on your serendipitous ‘first’ for Lundy, and nicely captured on camera for posterity!
