Herring Gull and Kittiwake wanderings

We've not blogged anything for a while, but with a quiet winter devoid of Siberian Chiffchaffs there's not much to report! But this week we've had a couple of exciting colour ring sightings, so thought we'd share.

On 4th May we heard from the assistant warden at the newly-accredited Lundy Bird Observatory, with news of one of our blue-ringed Herring Gulls; W:377, which was ringed as a chick on a roof at Tregoniggie Industrial Estate, Falmouth in June 2020. It is a bit of an explorer though, having been seen locally until August 2021, before being report on the French coast in February 2022. The next winter (January 2023), it was reported from a French landfill site, before returning to the coast in March. It was last reported there on 6th April before swapping France for Lundy.

Then on 15th May, we had a report of one of our Trewavas Head Kittiwakes, seen pair bonding and attending the beginnings of a nest maintenance on Skellig Michael, Co. Kerry, Ireland. KJ was ringed as an adult at Trewavas Head in 2017 and bred there (when the site was doing well) until 2020. As the main site started to fail, it then moved a short distance along the coast to Trequean Zawn in 2021, but then wasn't seen in 2022.

We rarely see movements between our sites and Wales/Ireland as it's far more likely for us to share birds with the French colonies. In fact, this is our first Kittiwake to be found in Ireland and only the second Cornish-ringed bird to make the trip.
