Last weekend, on Valentine’s Day, I attended the 14th Annual Gull Frolic, convening at the Winthrop Harbor Yacht Club. The last time I went was something like five years ago, my excuse either being that I was not in town or I didn’t want to drive the distance in my old car, but the still new Prius and I need to get out more, and I decided it was time to attend, if for no other reason than to see people in the Chicago area birding community that I have not seen for a while.

Gull identification is a fine art practiced by a select few. I do not count myself in that number, and yet by virtue of taking as many pictures as I could while freezing on the lakefront last weekend, I feel obliged to try to identify these enigmatic and entertaining birds. I should mention that one could go inside and be warm at any time, and there was plenty of food and hot beverages to keep us going, but the action was all outside.

Since the majority of the birds were Herring Gulls, the first order of business was to identify them all in the pictures until I came across something that didn’t fit the m.o. The most reliable field mark in most cases is the amount or lack of black on the wing.

Without the pictures I would be at a loss, as the gulls fly by so quickly if I didn’t stop them in time I would not have managed to study them as well. Although it was challenging enough just to hang on to the camera, and I often photographed the nearest subject which left me with a lot of Herring Gull pictures I probably do not need, at times it was fun. I think the gulls’ enthusiasm becomes infectious. Even with the pictures I am still often stymied by identification. It helps to know what gulls were identified that day, because it narrowed the possibilities down to seven species, six of which appear here (Herring, Glaucous, Iceland, Thayer’s, Lesser Black-Backed, Greater Black-Backed). Oddly enough, I have not one picture of a Ring-Billed Gull. I don’t recall seeing them either. This is one case when they were outnumbered by all the larger species.

As if to reassure us that we were not crazy, or if we were, we were in good company, gathering to watch gulls dive for bread in 45-degree below wind chill on Valentine’s Day – Ted Floyd of the American Birding Association and a million other affiliations gave a great talk on the phenomenon of crazy, or as he put it, “interesting” people who gather to identify gulls which, given their various plumages and tendency to hybridize, not to mention individual variation, unlike a male Northern Cardinal, for instance, that always looks red – making the challenge seem even more worthwhile, and now I’m thinking maybe I won’t wait another five years or so before I do this again.

One thing is certain: I know more about Herring Gulls now, after studying 1,000 pictures, than I did before, and this is the first time I have paid attention to cycles. This is no doubt the first symptom of Gullmania.

Unfortunately I did not get pictures of a few individuals that would have been easier to identify, such as an adult Great Black-Backed Gull, which is a bird that I have been able to recognize for years, but it has been nice to study the Glaucous and Iceland Gulls and to finally track down the nuances that distinguish Thayer’s from the Herring Gulls. I referred to the Peterson Field Guide, Gulls of the Americas by Steve N.G. Howell and Jon Dunn, and also Sibley Birds iPhone app.

Normally there are plenty of ducks to look at too, but it was so cold and there was so much ice, the ducks that were there were pretty far away. I only managed to capture a few Common Mergansers in flight and one Greater Scaup who was definitely “iced.” Click on the pictures to get a better view.

It’s hard not to wonder if the gulls mark their calendars every year for this event.
