Last week we had a Violet-green Swallow (would probably qualify as a "drab adult' per Sibley) for our quiz bird. I took the photo on one of 2 days that several of them were landing in front of one of the campground host's rv gathering up pine needles, presumably for nesting material. For this week, being a summer holiday weekend, we'll do what a lot of other folks might be doing - go to the beach to look at shorebirds (though it is probably a bit early in the season to see this species in this plumage). Good luck and great birding!
Sanderling is my guess.
By the way, the article I wrote for Bird Watcher's Digest about the skimmers that nested near the beach last year is in the current issue. And wouldn't you know it, the birds are back, or at least a pair of skimmers have nested again. This time they're on the beach right behind the Oceans condos. This is a cause of great consternation for the County. The nest has been over washed twice by high tides but so far they're still incubating. I'll keep you posted.
