Osborn, a passionate field biologist who participates to the core of her being three re-introduction projects aimed at saving three very different, endangered species: Peregrine Falcon, Hawaiian Crow (‘Alala)*, and California Condor. Sophie Osborn’s stories are personal and inspiring, but this is more than a personal memoir.

There’s no indication yet that the American Ornithological Union is considering lumping Blue-wings and Golden-wings into one species, but according to the researchers, a conservation case can be made for doing so, as both birds favor similar habitats.

Pough “with illustrations in color of every species” by Don Eckelberry, Doubleday, 1946. The National Audubon Society Birds of North America covers all species seen in mainland United States, Canada and Baja California. The press material says it covers over 800 species, so you know I had to do a count.

Artists rendition of Inkayacu paracasensis There are 17 living species of penguins, which make up their own Linnean family (Spheniscidae), which is the only family in the order Sphenisciformes. Penguins are flightless, but some species locomote over long distances on antarctic ice to travel between breeding grounds and the sea.

And so, I turn to Better Birding: Tips, Tools & Concepts for the Field , the new book by George L. It is an intriguing choice of species. These are extremely detailed, covering distribution, behavior, and plumage by age and gender (when relevant) and comparisons with other species in and external to the group.

“The Purpose of Field Guides: Taxonomy vs. Utility,” co-authored with Brian Sullivan, Michael O’Brien, Chris Wood, Ian Lewington, and Richard Crossley ( Birding , November 2009) proposed a standard avian species order for field guides, apart from the ever-changing AOS taxonomic order. Species are useful handles (p. 16, below).”

But getting a grip on gulls can be rewarding, and even within a large group of seemingly drab-colored, dump-loving trash eaters, there are spectacular species, like the dramatic Sabine’s Gull, the nearly mythical Ivory Gull, and easily one of the most sought-after species in North America, the mysterious Ross’s gull.

It’s not often that we have the opportunity to glimpse the home life of albatrosses, nor of any seabird species. An array of tools ranging from geolocators to satellite trackers to depth measurers to miniature cameras have been employed by ornithologists and biologists over the past twenty years, yielding scads of information.

The multitude of tools and ways you can enter/view your personal data is quite impressive, and it only continues to grow…although it might be on a subconscious level, embracing eBird more can be another kick in the butt to get out in the field.

Not only is it a very impressive citizen science project that manages to marshal the legions of birders around Canada and the U.S., Time will tell how much good science can be wrung from the data (due to observer bias, misidentifications, the vastly differing skillsets of contributing observers, under-birded areas, etc.),

In each case, "rational man" had to rethink human identity ¯ his species identity common to all other humans, or rather, all those counted as "human" and as part of the valuer´s community. Having misled us for so long about animals, science is initiating a revolution in our understanding. Why can we talk?

The species was in the news because some scientists had finally managed (or bothered – it’s much the same thing) to locate the population high in the mountains of the Solomon Islands, and catch and photograph one. If you want to know why most scientists support collecting this piece in Science explains it better than I can.

This is also where Johnson starts talking about the cost of the theft to the Museum and to science. In some cases, he took all adult males of the species or subspecies held by the museum. The skins were invaluable tools for ornithological, ecological, environmental research. Mostly adult males. The Flame Bowerbird, for example.

Unless you are nothing but the lowly diehard lister, for which you should feel much shame and embarrassment for, birders and biologists alike frequently want to understand birds on a deeper level than how to identify the age, sex and species of a certain individual. I believe in science. Science, for many years, has done no better.

Even if you don’t live in the summer range of a particular species, you may have opportunities to observe it while it passes through, especailly if you live in an active flyway, like I happen to. Because the ancestor of this species of bird migrated, and the migratory adaptation and all that entails were passed on.

In this book, rare birds are species “for which, on average, only 5 or fewer individuals have been found annually in North America since around 1950.” Species that were once seen rarely and have now become more common, like Clay-colored Thrush, are not included. Rare Birds of North America covers 265 species within these parameters.

Basically, Prum takes issue with the “adaptionist” interpretation of Darwin’s writings, which focuses almost purely on On the Origin of Species and the famous maxim, ‘survival of the fittest.’ Form develops according to function and sexual mating choices are based on choosing the mate best configured to deal with the environment.

Phenology is a vital science. As it turns out, a useful tool for the amateur phenologist is a dog. There’s some excitement in putting up feeders and in discovering which species are gracing us with big invasions this year (2011, Montana: Snowy Owls ) but much of the time its a slog. But good phenology is hard.
