This very nice Gull-billed Tern was found by Rob Taylor, it was roosting with a small gull flock which also contained a 1st summer Little Gull. The Gull-billed Tern spent a few days commuting between Penclacwydd and the shore south of Loughor Bridge (relocated here by Barry Stewart). Some video showing the bird at both locations can be found on the link below.
