The potpourri covers some interesting bird related science of the last few weeks, and the promise is this: I’ll get to that other stuff soon, I promise! If this was America, we might not be concerned because starlings are an invasive species, at least in North America. “We may be talking about 50,000 to 100,000 deaths.
While it makes a passing attempt to say not all scientists are like these monstrous fiends (or truly arrogant, as she dubs them) it mostly focuses on these monstrous fiends simply to prove that scientists in wildlife conservation can be monstrous fiends, particularly compared to the environment-loving oil industry of Alaska.
per cent of individuals of a species at a given time” and a vagrant bird as a bird that shows up outside of this range (p. The accounts cover vagrancy patterns for the family as a whole, reasons for vagrancy, documented examples of vagrancy for specific species and reasons that might account for those incidents.
During the decade, I submitted 1,219 checklists and observed 555 bird species, all in the U.S. After an initial period when all species are new, the lifers begin to follow a pattern. Thus, I can pinpoint my first pelagic trip, as it added 13 new species. and Canada. I’ve submitted 448 such checklists.
Given how far Hokkaido is from Europe, it seems a bit surprising how many bird species wintering on this Japanese island have a name starting with “Eurasian” Or how many of these species I have also seen in my parents’ garden in Germany. In science speak, this is named the optimal body mass hypothesis.
Ridgway himself had 23 species, 10 subspecies, and two genera of birds named for him, including Ridgway’s Hawk.) 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.
Before my trip to Washington the only species of puffin I had ever seen in the wild was the puffin of the Atlantic Ocean, the appropriately named Atlantic Puffin. The first obstacle was getting to the general range of the species, which is the west coast from northern California to Alaska and across to Russia.* I love puffins.
Kills in Canada, Alaska and Mexico are not included in the count. Hunting sandhill cranes in Kentucky is a bad idea from a public relations standpoint, considering the growing cadre of birders and nature enthusiasts for whom cranes are a touchstone species. A species which is the most abundant crane species on the planet.
Sarah Palin of Alaska, the scientific literature is very clear that polar bear survival is highly threatened in the wild. Sarah Palin of Alaska—that the Fish and Wildlife Service should not list the polar bear as threatened under the Endangered Species Act because science doesn’t support doing so—doesn’t persuade.
Picture being a Blackpoll Warbler being born in the boreal forests of Alaska. Almost as soon as you leave the nest, you have the strong urge to migrate to a place called “Venezuela” Can you imagine how many potential choices and decisions are involved in flying from Alaska to the Atlantic Seaboard, flying down the eastern U.S.,
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. What the Owl Knows: The New Science of the World’s Most Enigmatic Birds is a joyous, fascinating read.
Many, many things happened in the area of bird science this year, so this review can not be comprehensive. 08–20 Many bird species are in trouble, but the Hooded Grebe is really really in trouble. But I’ve compiled a sampling of this year’s news and events for your edification. But there was this one in Australia.
I’m going to start with a specific example: species accounts for Common Tern and Arctic Tern. How have these species accounts changed from The Sibley Guide to Birds , published in 2000 (heretofore called Sibley One) to The Sibley Guide to Birds, Second Edition , published in March 2014 (and heretofore called Sibley Two).
I’ve never known quite what to do with the two Cardinal sightings I have had near our church in Morelia, since that species is not supposed to be seen there, or to be migratory, but both sightings occurred in winter. I have seen two Godwit species at Lake Cuitzeo. One is unusual, the other is extraordinary. It means something.
