Appears to be the roost. Noisy and circling in a dense cloud. Too dark for photos. Estimate by 10s. Gut feeling for number was 250. We also counted about 1/3 of the group by 5s and got 75. Note: At compilation, we learned that Danielle had also found part of the island roost here, at the same location, and also counted 200 birds. So, our subteam (2 of us) arrived at the number 200 three different ways, and Danielle independently arrived at the same total. (She doesn't believe this is the whole roost for the island.)
