St. James's Park: Ross'sling'swings
See the downwash-tickled water texture in large.
Ross's geese drinking
Swan vs. pigeon (1/3)
Swan vs. bully
This is shot 5 of 5 in a series (right from here); I particularly like 1/5 and 3/5, but this looks like the reverse angle of my Christmas Day blip which made it stand out for me.
My mother and I went to St. James's Park in the early afternoon to see the Ross'sling and its kin (all four were together!); it was overcast and dark, but it was lovely to see them, and the pelicans, and an avian affray over bread...
I took lots of photos of the pelicans up close in portrait format because a friend asked for a pelican picture for printing on an A5 card, and upright images are more suited for the purpose...
Others are all here (or right from Pelican plumage)
