For one thing, we become more aware of cultural biases in our science (new findings on warbling female birds, for example, reveal both gender and geographic biases). Many popular science books have neither. As Ackerman explains in her Introduction, studying extreme behavior brings new insight into what we think we know.
NARITA, JAPAN, DECEMBER 2012 – The art and science of layover birding deserves more rigorous study and perhaps a federal grant. What I learned convinced me to block out a full day to experience my first taste of Japanese birding. Lisa is an American who recently moved to Japan.
While they winter together on some of the Western islands of Japan, they then migrate along very different pathways, one on the mainland and one along the string of Japanese islands. Judging from my experience in the human world, a very predictable result.
It includes stunning photographs by Tipling of eagle hunters (as in Kazakhs who hunt with eagles), Stellar Sea Eagles in Hokkaido, Japan, and Black Kites at the dump near New Delhi, India. The Birds of Prey chapter, on the other hand, is 18 pages long. Cocker focuses on the love-hate relationship we have with raptors.
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.” Where it is not – for example, in Japan – it will have difficulties finding a partner to mate.
In science speak, this is named the optimal body mass hypothesis. For Coal T**s , resident birds were found to be slimmer than transients, which makes sense as they have better knowledge of the available resources and thus less volatility in their food supply (and of course slimmer birds are better at not being eaten themselves).
They are also raised commercially for meat and eggs, as described in that beacon of ornithological knowledge, the World’s Poultry Science Journal. It seems the ones I got decent photos of are all juveniles – it generally seems to be easier to get photos of juveniles as they have not quite learned to avoid humans.
If Japan Can Why Can’t We : 17,000 views (2 years – 39,000). The Red Bead Experiment with Dr. W. Lessons from the Red Bead Experiment with W. Red Bead Experiment (a longer video than the excerpts from this that are listed above): 2,100 views (2 years – 5,300). How Did We Do on the Test?
So sorry, but this is a necessary part of our thought experiment!) Let’s do another thought experiment. First, I set the dial to produce the kind of high energy radioactive radiation stuff that would be emitted by an atomic bomb, and calibrate it to dose you (sorry, but this is necessary for our thought experiment!)
I’m sure many of you have had similar experiences. Jennifer Ackerman points out in the introduction to What the Owl Knows: The New Science of the World’s Most Enigmatic Birds , that we don’t know much, but that very soon we may know a lot more. But what do we know beyond these commonly seen and heard behaviors?
