Many more gulls tonight, despite a long-boat race in progress when I first arrived at 3:30pm. The early gulls just pushed tighter to the far side as the two crews and safety boat passed. Some hurried counts were 3,000 gulls in total at 4:30pm probably an even split with BH gulls, LBB and Herring gulls, with many LBBs coming in at 4:40pm. 6,000 plus at 5:10pm (1,500 BH gulls, 2,000+ adult LBB, remainder Herring gulls and unidentified juveniles) with more LBB still arriving. The roost split into 2 groups with the majority of the BH gulls and smaller gulls settling towards the dam and the larger gulls up beyond the small western inlet with the two yellow buoys. Light was much better as well for picking out shades of grey. The 2 Glaucous gulls appeared at 4:45pm, the paler bird dropped in among the BH gulls, the sootier individual in with the Herring gulls. The large first winter gull with the dipped-in-ink bill appeared again this evening, probably Argentatus though it does give Glaucous vibes (Viking gull?). 10 GBB (4 adult, 5 2cy, 1 3cy), 6 Yellow-legged gulls (at least 3 adult, 2 3cy and a 2cy), 6 Med gulls (5 adult, 1 2cy). 110 Canadas was the most for a while, they've been absent on some visits. 4 GC grebe.
Rosebush reservoir: All the duck were towards the far bank near the dam. C20 Mallard, 15 Teal, 9 Tufted duck (6m), 2 pair Wigeon, single GC grebe.
