Red Knots

When I arrived at Trestle Bay (Ft. Stevens, parking lot D), around 3:30pm, there was a lot of sand exposed, allowing me to walk almost all the way out to the trestles (below).

But an hour later, the water was quickly filling back in (below).

Here is the view looking back towards the bunker and parking area when I first arrived and walked out there (below).

The water started to quickly fill in about an hour later, perhaps driven by the west wind (below). No one photo captures all of the birds. I counted about 600 birds in this photo (plus David Bailey & daughters in the background).
