My job today was to drive a boat around the shoreline of a large, wonderfully clear lake and map and identify the emergent vegetation. All this in partly cloudy, 80 degree weather. Not a bad gig if you can get it. Even if you have to work with the intern. (No really, he's a great guy, I just don't like having "teaching others what their future job may entail" as part of my own job description, for more than a day or two. That's just how I am. Oh well.)
In the process, we encountered this bird, and I happened to have my camera ready! How often does that happen? I knew right away it wasn't one of the usual ring billed gulls, but my mistake was thinking it was still a gull. After getting back to the office, and comparing the picture to my Sibley's guide, it turned out to be...a Forster's tern, adult non-breeding plumage. I don't think they occur around here, in late July, too often. Anyway, it was maybe a first for me and a great chance to show the intern about looking at the whole picture. I don't know anyone else around my office who takes the time to identify birds.
