I haven't had much time to photograph the shorebird migration so far, but here's one from earlier this week when I had an hour or so to spare near my place. That beach was rather empty, thanks to the city hiring someone with a drone helicopter to spook all the geese away...and along with it gulls, herons, and shorebirds away from the public beach (heaven forbid there are birds in a wild place they built a park in!!)...but the birds slowly simply return once that fella is gone from his early morning shift.
Canon 7D + 500mm f/4 II + 1.4TC, manual exposure, evaluative metering, 1/640s., f/5.6, ISO 800, natural light, handheld, small crop to help the composition, toned down and gave more saturation to the bright blue BG.
