It has also found its way to Japan where it is considered to be an invasive species. Now and then individual catfish of various species hunt nearer the surface and larger catfish such as the American Channel Cat will take a duck or other water bird. The range of size of sampled catfish ranges from 0.9

I haven’t yet been birding in Europe but whenever I occasionally skim a field guide about the birds on the other side of the Atlantic, I’m always encouraged to find that I’m already familiar with many species found over there, even though most of my birding experience has been limited to eastern North America.

Plasticity in humans is probably modulated primarily through experience and enculturation. Most likely, all individuals of a given species have very similar genes guiding very similar developmental processes, but produce different results because the plasticity itself is selected for.

There were opportunities to go to far flung places like the islands of the Pacific or the coast of Canada or the Yorkshire Dales… Anyway, as I was obsessed by Africa at the time, I leapt at the opportunity to go to Namibia to collect samples of bat DNA for a biogeography project. And then, there it was.

This would have allowed you to summarize your experience in sentences such as “A total of 98 boluses regurgitated by 52 chicks aged 1 day to 11 days after hatching form the sample and are shown to contain 323 food items.” Now I just need to find some grant money to try and prove my theory.

There is also text, distribution maps, a dark red bar “warning” about similar looking rare species, and conservation symbols. So, how do you find the species account for Kestrel if falcons are not placed between woodpeckers and parakeet?

I’m sure many of you have had similar experiences. I’m wondering as I write if you are shaking your head, uneasy that all these FACTS will interfere with your love of observing owls, an experience that easily borders on the mystical for some of us.

This is a sampling of the literary array Rogers has gathered from birders who write and writers who love birds. The essays range widely in place, bird, and voice, though the emphasis is on the North American. Though all are well-written, there are several that standout for excellence of the writing, challenge of topic, or stylistic daring.

It is helpful to have a sample paper. For example, fancy words will be used where normal words might seem appropriate: birds of the same species are “conspecifics” (and they will never, ever “flock together”).

Honeyeaters are “active, noisy and pugnacious” and there are a lot of them–76 species–in Australia. The colored font is also used to indicate measurements, voice, and notes.

Once considered a separate species, the Mexican Duck was lumped with Mallard in 1983 after studies indicated a high degree of hybridization, and that is where it’s remained ever since. And while we’re at it, what’s your experience with Mexican Ducks and Mallards in Mexico, Arizona, New Mexico, and Texas?

Unlike other bird races where participants keep tight-lipped about bird species as mundane as a House Sparrow , this event gives a prize to the team that helps the most. But isn’t all of that data sharing counterproductive for a bird race where the team with the most species wins? This is a Masked Shrike.

Fortunately, Alan Tilmouth, a beat writer with pelagic experience, expressed an interest in the book as well. A respected expert on seabird taxonomy, Howell summarizes the current state of a field, which, he says, “has followed a long and tortuous path, with much debate about whether separate populations are species or subspecies” (p.15).
