Face it. Half the time … most of the time, really … you use your Peterson (or some other favorite “field guide”) as a checklist. You see a bird and you pretty much know in your head what it is, but you need to look it up to see what the three or four similar…

How are birds related to dinosaurs, crocodiles, and pterosaurs? Where do birds live, and not live? How many bird species are there, and how many actual birds, and how does this vary across the glob? What about endemics?; Where ate the most local species found? Mike Unwin’s The Atlas of Birds: Diversity, Behavior, and Conservation…

Birds don’t live in nests. They make nests for specific purposes, use them for that purpose, then abandon them. Or, sometimes they don’t abandon them, but rather add on and use them again and again, but in between they don’t live in or on them. Well, sometimes they hang out on them a lot. And…

Here in the Northern Hemisphere, many of our birds fly away in the fall. Other, very cool birds from even farther north, depending on where you live then arrive. But just about now, where I live, we are at the tail end of the migration out and not quite at the migration in, so this…

Rapid climate change can cause species extinction. But if a species is highly mobile or wide-ranging, then that effect may be attenuated. And, more rapid climate change would be more serious a problem than less rapid climate change. Therefore, there should be a relationship between species mobility (migration) and the rate, or velocity, of climate…

To my Ukrainian Readers

Повідомлення у блозі я написав для 10 тисяч птахів, з питань міграції, був переведений березня Ruszkowski на український Langauge, і доступний для Вас, щоб прочитати тут: Питання про міграцію Я сподіваюся, що ви любите читати його стільки, скільки я сподобалося писати його! Я не знаю, скільки задоволення перекладі це було, одначе! Дякуємо Березня.

People who watch birds identify them, and that process is integral to what makes birding interesting. But the best practices for identifying birds appear on the face of it to conflict with evolutionary concepts of birds, and this can lead to both sloppy thinking and missed opportunities

The Birds of New Jersey

I’ve recently reviewed bird or nature books for some fairly exotic places (see this for all the reviews) including the Antarctic and the West Indies. Now, I have a book on the birds of one of the most exotic places ever: New Jersey! OK, if you are from New York like I am, you know…

I’m sitting here looking at Antarctic Wildlife: A Visitor’s Guide. I’ve never been to the Antarctic so I can’t tell you what I think of this book from the pragmatic angle of how well it works as a guide, but I can tell you that I’ve learned a number of things just looking at the…
