Cardiff foreshore

Significant post-breeding arrival of Black-headed Gulls (350+, including 1 fledged juv) on this evening's high tide, plus Mediterranen Gulls (14: 1 ad summer, 1, second-summer, 12 first-summers), though frequency of sightings suggested there were more first-years present than this conservative figure. Most flew into Rhymney Estuary at high tide.
