The definitive photographic guide to North American gulls

Gull identification can be challenging for even the most seasoned birder. While these birds are common to coasts, lakes, and rivers, they exhibit remarkable plumage changes related to age, which is sometimes complicated by similarities between species and a readiness to hybridize. This book provides an invaluable identification guide to all regularly occurring gull species and subspecies throughout North America. It is packed with the very latest research on field identification, updated taxonomy, current distribution trends, color maps, and helpful notes on natural history, aging, and molt. The Gull Guide integrates the essential elements that are critical to understanding gulls, setting an entirely new standard for identifying and enjoying these marvelous birds.


Features more than 1,800 superb color photosCovers 36 gull species as well as 7 of the most commonly encountered hybrid gullsGives equal attention to rarities from Asia, Europe, and South AmericaDescribes the key characteristics of all age groups, from juvenile through adult plumagesInnovative photo collages give side-by-side comparisons, enabling readers to distinguish between similar species and avoid common pitfalls associated with gull identificationComes with a one-of-a-kind “cheat sheet” describing key features of select Larus speciesA must for the bookshelf of every birder and ornithologist

Even master birders with decades of experience will often concede that they struggle with identification of gulls. These birds are so diverse yet so similar, have so many different phases where they look drastically different, yet very similar to one another in similar cycles, and sometimes telling them apart is a matter of the edge of a single feather or something equally ridiculous. As a result I was excited to get my hands on a copy of Amar Ayyash's The Gull Guide: North America.

I myself am not a master birder. While I am not a complete amateur since I have some years of experience under my belt, I only very recently started venturing out into interactions with other people who can teach me new things outside of my own reading and studying. As a result a guide like this is exceptionally valuable. The reason this book works so well, in my opinion, is that it does not fall into the trap that some guides do and trying to simplify something complicated. The author discusses this in how some people do not want to teach the different feathers and parts of the bird so as not to confuse someone new. However, with gulls as well as some other species, being able to tell these minute differences apart is critical. Ayyash also critiques the "x winter" labeling style since it's inaccurate given the differences in molt and breeding months between species and instead uses a far more accurate "x cycle" labeling structure.

The information as well as the many charts and labels are indeed somewhat intimidating, but I found myself completely engaged. I was not intimidated in the way one can feel like they're drowning in information that's impossible to parse. There are copious amounts of photos showing each bit of information from a different angle. All of the photos have clear descriptions that help to learn things by sight quite well. Each section on an individual species has tons of photos and many different ways of identifying and thinking about the birds. There is even a section on aberrant birds such as leucistic and melanistic gulls.

Ayyash also offers general birding tips on when to step back and when to hyper focus. He gives examples of confusing identifications that were made in error. The only criticism I have of the book's structure is that the multitude of images in an average sized book means that it's tough to see some of the details in smaller images. But, I'm not sure this could have been created any other way because making the images large would make the book so massive and heavy as to be unusable. I'd rather have this structure than fewer images.

Approaching the material this way not only helps one see the whole bird and learn more, it gives the reader multiple ways to focus on the birds. What I mean by this is that people learn and perceive things in different ways with different traits dominating their minds. This gives enough information on each identification type to be used by each person. Because it is full of photos and the print is high quality, it is a heavier guide. Sort of like a medium-sized Bible. So, to use in the field, I imagine this guide would be better for something like a stationary birding session. However, as someone who uses both apps in the field and print guides at home, don't let this deter you. There's something about book guides in hand that aid identification in ways that are different than those on electronics, including the wonderful pages available on Cornell's website. I can't even describe what this is, I just know that there are many times that I've been stumped only to open a book that makes everything clear to me. This book is indispensable as one of those on my shelf. None of my other guides, of which I have many, managed to make it possible to more confidently identify gulls.

I still have a lot of practicing to do. Recently a group of ring-billed gulls in multiple cycles stood in a nice little line for me. Thanks to this guide, I was able to pick out the features and cycles of each which was a great exercise with an abundant species I'm somewhat familiar with. The next time a rare bird alert goes out for a gull, I'll be much more confident in my ability to find that needle in a haystack.

As a complete non-expert in gulls, I feel like this has to be the definitive work on the subject. The knowledge presented here is remarkable, as are the array of pictures.

That said, I have a couple issues, both of which relate to the presentation and not the content:

1) I wish the book were bigger. The print and even some images are smaller than I'd like (even after updating my glasses). I saw someone else point out that this isn't like to be a book you tote with you, so making the pages bigger wouldn't hurt its usefulness (it's more a guide to leave on the car seat than to stick in your pocket).

2) I would benefit from comparison pictures. Ayyash will say that two species can be distinguished by, idk, one having a more rounded head. And then you have to flip back to find a nice oval headed example of the other species. Having a few pictures of the most confused species together would be helpful. [Another reviewer mentioned the desire to have a picture of an adult at the start of each species account, and I have to agree, even acknowledging that part of the challenge of gulls is how often you're looking at a bird that isn't the quintessential-looking adult.]

For these reasons, I'm not entirely convinced that Dunne's Gulls Simplified isn't more useful to a novice, although anyone with even a remotely serious interest in learning about gulls should certainly own this one.

As with all of my field guides, I’ve never read it all the way through. I am working my way through it though and really love the writing, the photos are excellent, descriptions within each photo along with the captions are excellent too. I will post more as I make my way further through it.

Jam packed with loads of pictures and information. Pretty hefty guide--the electronic version would be more practical in the field. Text is a small font.
I appreciated the suggestions of potential new names for the birds named after people.

Not a book to read right through. More of a reference volume but have gone all through it even if I didn't read every word. Many pics, could be larger. Would have liked an adult picture at the start of each chapter. Gulls are still difficult to ID.
