This was on a green turtle nesting beach. We visited at night with a guide and saw the green turtles climb ashore, lay eggs, and return to the water.
This bird was seen approximately 3-4 times, each time at low-tide mark. The initial observation was during a regular shorebird survey. Birds that we normally see include Greater Yellowlegs, which is what we first thought of, but it didn't look quite right for a Yellowlegs. The legs were not yellow enough - rather they were a grey-green-yellow. We estimated that the bird was between 24-28cm as it was hanging out with some Black-bellied Plovers. We went down a few times after the initial sighting at high-tide and did not see it. All other sightings were only at low-tide. High quality pictures were taken, and from those we saw that the rump is lightly barred. After much discussion we came to the conclusion of a non-breeding Red Knot, however as far as I can tell this is the first record for the Caribbean Coast and we are just a bit hesitant to call it without some other opinions!
