1. Is photo documentation necessary?

"a picture is worth a thousand words" And with the prevalence of cameras its always a good idea. Now if they can only make them a *LOT* lighter...
1a. Arctic Terns are common and easy to find, so documentation is not important In Maine perhaps...
1b. Arctic Terns are rare, at least in most years, and hard to identify, so documentation is very important Prior to their occurrence at Cupsogue being divulged I think I speak for many when I say that trying for that species was on few birder's radar.
2. Where do Arctic Terns occur in NYS? Worth checking any tern nesting or loafing location at this time of year.
2a. Arctic Terns occur everywhere, from far offshore to small upstate lakes and the Great Lakes; there’s no pattern. If you don't look, you won't know.
2b. Arctic Terns occur at Cupsogue; searching elsewhere is a masochistic waste of time Ha ha!
2c. Arctic Terns occur regularly around all of Long Island’s ocean inlets. Those are probably the best places to look and (occur regularly) is being sussed out as we speak.
3. What does “second-summer type” mean and how should I feel about it? It means the Terns themselves take a relaxed approach to plumage sequence and I can live with that.
3a. When I see the term, “second-summer type” I want to throw up and nobody has the right to make me say it. nauseous perhaps, but whatever.
3b. The term, “second-summer type” is going to keep on coming up so we should tolerate it, even though it doesn’t refer to anything that’s biologically valid. What's wrong with 'sub-adult' plumage. Not juvenal, not adult...  
3c. The concept of “second-summer type” terns is like a revelation that unlocks the secrets of the universe. Can I have some of what you're smoking?
4. Does Arctic Tern occurrence actually dip in late June, between peaks in mid June and early July, or is this an artifact? see 2c

The 2018 summer tern season on Long Island has been great so far and is going to set records for Arctic Tern in several ways: total records, total observers contributing independently documented records, and records from sites apart from Moriches Inlet, such as Rockaway Inlet, Jones Inlet, and Old Inlet. With apologies to those who have had enough ternology already, I’d like to raise a few points now, just past the mid-point of the season, while we still have time to collect lots more data. Here are four debates that I’ve been dealing with:

I’ve uploaded some figures to my flickr site, based on my own observations of Arctic Terns on Long Island, which I think shed light on these debates. Fellow tern enthusiasts, let’s see what we can do.
