We have two first sightings following fledging although the GBBGull's are not the same age.

GBBGull P:65D was hatched and fledged from the North East arm of the Break Water  in June 2019

It waited until the 19th July 2023 to show itself and it was back in Portland Harbour on the C head of the Bincleaves arm which is attached to the Weymouth mainland.

                                                     Photo and sighting from Mark Rowles.

GBBGull P:57F didn't wait as long to show itself seen on the River Adur opposite Shoreham Airport Sussex. Seen there by Richard Fairbank on the 20th July.
