Thus, the cattle we raise for meat and dairy are sometimes called Bos taurus while the extinct wild form is always called Bos primigenius. Some time after the Spanish encounter with the Turkey, birds were brought back to Europe where they were raised and became an important source of food and fancy feathers. Which would be weird.

Photo by Adam Riley (Rockjumper Birding Tours) Despite initial appearances, these birds are in fact very large passerines (13-16 in) and research has shown them to be an ancient basal offshoot from the passerine evolutionary tree. White-necked or Yellow-headed Picathartes, Bonkro, Ghana.

Raised in and around the West Texas steppe country where temperatures reached 100 degrees with regularity, he began life as the Dust Bowl and Great Depression converged. That summer of 1938, when he was ten years old, Cade read of two brothers, Frank and John Craighead, who wrote of their experiences with falcons in National Geographic.

What I didn’t know was how this relationship actually works: the mechanics of Red Knot migration, the reduced digestive systems necessary for their long flighta, the need to fatten up quickly so they can fly to the Arctic and breed, how they compete with other shorebirds and gulls and, it turns out, humans, for horseshoe crab eggs.

Marc Hauser, a cognitive psychologist at Harvard University, recently opened his own such research lab and has 1,000 dogs lined up as subjects. Horowitz and other scientists are now running experiments to determine what a behavior, like a kiss, really means. Other facilities are operating in the U.S. and Europe. Going to the Dogs.

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. But what do we know beyond these commonly seen and heard behaviors?

Many birders keep personal birding lists or life lists, documenting the species they have seen throughout their birding experiences. The concept of a big year gained significant attention through books, such as “The Big Year” by Mark Obmascik, which chronicled the experiences of birders participating in competitive big years.

This is a delightful book, large (8-1/2 by 11 inches), filled with Sibley’s distinctive artwork and an organized potpourri of research-based stories about the science behind bird’s lives. His art is beloved (if you have owned a Sibley calendar at least once in your life, raise your hand) and his bird expertise is widely respected.

With regard to the Grey-backed Thrush , “further research should focus on identification of nest predators, implications of nest exposure and begging calls on nesting success, and breeding habitat requirements at different spatial and temporal scales of Grey-backed Thrush in fragmented landscapes of northeast China.”

The experience was marvelous — but it also weighed heavily on me. Here’s a diagram, available on the Audubon site , that compares its 2000 range with its anticipated 2080 range: Only 1 percent of the bird’s breeding range remains stable between 2000 and 2080 if global warming continues on its current course.

Take a look at this little Blue Tit and admit that you have never seen a more pathetic picture of a bird that combines the colours blue, yellow, green, white, and black in the most marvellous way you have ever seen: Recent research has shown that Leonardo da Vinci showed a Blue Tit to his model while he painted the smile on “Mona Lisa&#.

Their goal is simple yet lofty: “We hope these redescriptions will arouse some interest in the chewing lice of shorebirds among researchers working with lapwings” As I mentioned in one of my posts this spring, for me the personal start of the migration season is when I see my first male colorful flycatcher.

Mallards , of course, bring new meaning to the term dabbling duck , what with all those wild mallard hybrids and domestic cross-breeds running around. Researching this single hybrid revealed that teals are as liberal with their love as mallards! The more I learn about ducks, the more impressed I am with their blatant promiscuity.

Penguins are also bellweathers of climate change; dwellers of remote areas you’ve (probably) never heard of; creatures who have developed unique, innovative ways of adapting to the harsh environments where they breed and rear chicks and the water environments in which they feed and swim.

Those large international agencies use reputable local ground agents, and in my experience this creates a safety cocoon around the travellers. And the answer to the question I am raising here is, yes, I would travel to Sri Lanka in the next period. And now is the time to go back to the Bradt travel guide to Sri Lanka by Philip Briggs.

Do you really need to have Kai’s birding experience further detailed not just by month but a level below? As with Chinese male humans, having your own building is still vital to raising young. There was a breeding pair at Binjiang Forest Park this June. Most scientific research really just proves the obvious.

I have written about the interesting sex life of these jacanas a few times already (short version: female mates with male, lays a bunch of eggs for him to incubate and raise the chicks, leaves him, finds another male, repeat). The Little Grebe is of course a very common bird that can still surprise by its beauty in its breeding plumage.
