40+ of these round, medium, shortish-billed mostly soft grey sandpipers - some of the photos show relative vs. other shorebirds (twice as tall as dunlins, same shoulder height as black-bellied plover, half the height of godwits, etc.)
group of the ruffs after the tide has risen, various photos showing size vs. avocets, lesser black-backed gulls, sandwich tern, etc.
The smaller waders here. Not the Avocet, The Godwit or the Gull.
fourth from the left in this group of Great Knots
not the Brown pelicans, or the peep (likely a Sanderling)
