New studies find that: when birds migrate from the Arctic to South America, fragments of mosses, fungi, and other “diaspores” hitch a ride (and a similar phenomenon may have spread acacia trees from Hawaii to an island in the Indian Ocean); caterpillars which feed on many different types of plants are more attractive meals for birds than caterpillars (..)
In the popular imagination, Hawaii is a tropical paradise. (No, With climate change appearing to expand the skeeters’ range, according to recent research in Science Advances , the birds have fewer safe places to hide. And if you’re lucky enough to be on the island of Hawaii next weekend (Sept. Take birds.
He offered two rewards for consideration: (A) $5,000 in cash or (B) a trip to Hawaii (of equal value to the cash). Then he asked two different questions of them: Which reward would you prefer: the cash or the trip to Hawaii? Hawaii is a reward they’ll remember forever. Hawaii is a reward they’ll remember forever.
It contains numerous citations to the literature, as the process must be based on the best available science. The number of wild geese has increased dramatically: in 1960, there were an estimated 30 birds on a single island, Hawaii, but the current estimate is 2,855 on Kauai, Molokai, Maui, and Hawaii.
In Hawaii I stood on a beach as albatrosses fledged and Tiger Sharks prowled for the less successful ones. There is no feeling in the world like knowing your helping something you care about, whether its sharks or puffins, protecting forests or reefs, advancing science or communities. Amazing stuff. I still have that marker.
A highly imprecise reward is a day at the spa or a dinner for two or a trip to Hawaii. In a terrific paper on the subject, Scott Jeffrey compared the motivational qualities of two similar rewards – a trip to Hawaii and a $5,000 trip to Hawaii. Incentives. Good incentives rely on high degrees of precision to generate motivation.
This is probably one of the reasons Daniel Lewis,the author,turned from writing a popular biography to a history of ornithology as a science and the ornithologist as a profession. Lewis is Dibner Senior Curator of the History of Science and Technology and Chief Curator of Manuscripts at The Huntington Library in California.
49-50) She is also adept at writing about conservation’s larger context in terms of its history, public policy struggles, and the science behind species re-introduction. Well-researched and footnoted, these sections never feel disconnected from the more personal sections.
In addition to my monthly posts here, I have also written short pieces and feature articles that rely on bird-related scientific literature. My impression is that few birders dive into ornithological and ecological papers, but there’s much to be learned, even if the reading can be tough sledding.
The rest of Mexico is not included, nor is Hawaii (which isn’t in North America, after all, but has been accepted as part of the American Birding Association area). The National Audubon Society Birds of North America covers all species seen in mainland United States, Canada and Baja California.
David Pavlik is doing a photographic big year, trying to photograph 500 species in the ABA-area in order to fundraise for the American Bird Conservancy’s work with the endangered bird species of Hawaii. You can follow along at Birding for Conservation , where I learned that David has already reached 270 species for 2013.
A bit surprisingly (at least to me), the Kalij Pheasant has been introduced and established as a gamebird in Hawaii. Bonus note for science nerds (not related specifically to birds): Whenever Chinese researchers give percentages, they do so up to two digits behind the decimal – thus the exact percentages in the HBW citation above.
