The Bonaparte's Gull again present on the incoming tide from 0545 - 0645, off the imperial recreation ground, and still there when I left. It flew over to Mudbank briefly before heading back to the Black-headed Gull flock, dip-feeding off Shelly Beach. Attempts at photography again hampered by distance and poor light.
Good to meet up with Mark this evening as the bird fed well out on the river, at times close to the floating café. It was again feeding with c100+ Black-headed Gulls but 2 Sandwich Tern, one or two first-summer Mediterranean Gulls and a first-summer Common Gull were also present.
