The bulk of wilderness is in Alaska (more than 57 million acres), most of it designated by the Alaska National Interest Lands Conservation Act (ANILCA) in 1980. There is also a research institute dedicated to wilderness: the Aldo Leopold Wilderness Research Institute is an interagency facility located at the University of Montana.
A new paper out this month attempts to paint the most comprehensive picture yet of the origins and diversification of the American sparrows, wood-warblers, blackbirds, cardinals, tanagers, and their kin, an enormous group of birds more than 800 species strong. The paper is by leading researchers F. Keith Barker, Kevin J.
Fish and Wildlife Service has listed the “Rufa” population of Red Knot ( Calidris canutus rufa ) as a threatened species under the Endangered Species Act (ESA). The other sub-species, Calidris canutus roselaari , migrates along the Pacific Coast and breeds in Alaska and the Wrangel Island in Russia. Conservation'
Though Ron is based in Ontario his reports are eagerly anticipated by birders across the northeastern United States and eastern Canada because it takes into account a vast array of data to figure out which irruptive species might show up where. Photo illustrations by yours truly have been added. GENERAL FORECAST. COMMON REDPOLL.
Nearly 70 species of parrots have been recorded flying free at some stage or another in Miami, including Hyacinth Macaws. Dozens of other introduced bird species, largely escapees from pet owners, now call Miami home. But I couldn’t help but get more excited about the countable species as opposed to the uncountable ones.
The Red-breasted Sapsucker ( Sphyrapicus ruber ) and the Red-naped Sapsucker ( Sphyrapicus nuchalis ) were considered different forms of the Yellow-bellied Sapsucker ( Sphyrapicus varius ) until 1983 when they were split into separate species. The bird shown above arrived at my house at the end of October, a new species for my yard list!
His second book on migration is a tale of many birds and many research studies all connected by the theme of migration and by his thoughtful narrative voice. Even if you have read about these research projects, Weidensaul’s accounts offer fresh angles and updated information. is through the personal and the specific.
The USVI are smaller and have fewer habitats and, as a result, fewer bird species. Much of the research regarding Caribbean ecology and ornithology has been conducted in Puerto Rico. Puerto Rico has a checklist of 269 species, 207 of which are migratory and the USVI has a checklist of 149 species, 124 of which are migratory.
Though Ron is based in Ontario his reports are eagerly anticipated by birders across the northeastern United States and eastern Canada because it takes into account a vast array of data to figure out which irruptive species might show up where. See individual species forecasts below for details on each species. GENERAL FORECAST.
Pelee National Park – Ohio Santa Ana National Wildlife Refuge – Texas These locations offer a variety of habitats including marshes, wetlands, forests, coastal areas, and deserts, attracting numerous bird species throughout the year. Please note that the availability of specific bird species may vary depending on the season.
At the edge of the Oregon Cascades, rain is expected, and the researchers and scientists thought little of it as they continued about their daily tasks. According to the Cornell Lab of Ornithology, “its roughly 3,900-mile movement (one-way) from Alaska to Mexico is equivalent to 78,470,000 body lengths.”
There are 35 raptor species that have a presence in the United States and Canada, 56 (more or less) if you count by subspecies, and they are all covered in admirable, exhausting, unbelievable detail in B irds of Prey of the East: A Field Guide and Birds of Prey of the West: A Field Guide by Brian K. Species Accounts.
. “Invasive&# is an ugly word, and ugly consequences have come from many of the explosive range expansions we’re most familiar with, whether of exotic species or even of native species with their normal restraints removed. Especially of all the species that had been introduced to the US. Get yours today!
Taking inspiration from Matthiessen’s 1967 book (long out of print), which combined his natural history essays with species accounts by Ralph S. I did a little research and found plovers and snipe o n menus and in cookbooks of the time, though I still haven’t found recipes for Dunlin or Dowitchers.
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. It seems extra-pair paternity is very frequent in this species.
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.,
This second edition covers 685 species found in the continental U.S. and Canada, including some species as far north as Alaska, an increase over the 500 species covered in the first edition. McKnight not included in the first edition; updated nomenclature; and artwork positioned opposite the species descriptions.
A number of years ago I was granted the privilege of flying into the Kuparuk Oil Field, above the Arctic Circle in the remote regions of the North Slope Borough in Alaska. But, he continued, some – but not all – of the researchers drove him nuts. Their attitude was “the rules don’t apply to me, I’m a researcher.”
Secondly, much of the appeal is that this is a bird we don’t see in the UK very often, for Waxwings are an irruptive species, and in most years only a few ever reach our shores from their breeding grounds in the boreal forests of Scandinavia. For many years Waxwings were my bogey birds that I kept on missing.
For my new book, due out in 2012 from Houghton Mifflin Harcourt, I’ve been researching sandhill crane hunting. Kills in Canada, Alaska and Mexico are not included in the count. Initiating a hunting season on a large, charismatic species like a crane is no way to resuscitate hunting.
“I’d witnessed Peregrines and Gyrfalcons in the fall of 1949 while I was doing undergraduate work at the University of Alaska. ” Cade was later to comment, “1951 was when I first saw the high-flying style of hunting performed by the wilderness-inhabiting Peregrines of Alaska.” And grow they did.
Ridgway himself had 23 species, 10 subspecies, and two genera of birds named for him, including Ridgway’s Hawk.) The next time you hear birders complain about lumping, tell them to be thankful they weren’t around in the late 19th and early 20th centuries, when hundreds of supposedly new species were re-assigned subspecies.
In Europe, most of them winter south of the Sahara but an increasing share winters north of it – which sounds like an interesting research topic for people who, ahem, find such topics interesting. It is rumored that one of the researchers later became a software developer. No need to remind us all the time.
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.
According to research newly published in Nature , when these shorebirds arrive at their Arctic mating grounds, they don’t just shack up with the nearest honey, or waste time competing with the other dudes for the attentions of the loveliest potential mates.
If this was America, we might not be concerned because starlings are an invasive species, at least in North America. Their total population, from the Baja Peninsula to Alaska’s Aleutian Islands, is estimated at somewhere between 1 million and 3.5 Researchers are wondering if the die-off might spread to other birds or even fish.
Researchers have also learned that the cancer-causing chemicals that form in beef as it cooks also tend to form in chicken. Never mind that the bulk of the fat in Starbucks's beverages comes from the milk -- yes, milk ! -- of another species. Unfortunately, switching from red meat to chicken does not help very much.
Ackerman’s new book is about owls and owl research–the knowledge recently and currently being discovered through DNA analysis, new-tech tracking and monitoring, and old-fashioned fieldwork under the auspices of organizations like the Global Owl Project and the Owl Research Institute.
03–19 Interesting research on microevolution in swallows was reported , suggesting that swallows in one area may be adapting to problems unique to living near, and hanging out on the surface of, a highway. 08–20 Many bird species are in trouble, but the Hooded Grebe is really really in trouble. So, look for that.
In Alaska, they were found to mimic 30 different species ( source ). Maybe they have decided to boycott species with Russian-sounding names as a way to protest against Putin’s policies. Red-flanked Bluetails make shorter stopovers during spring migration (average 1.7 days) than in autumn average 3.4
Like the Eastern Crowned Warbler (which eBird mysteriously calls a “boldly marked songbird” despite its similarity to about 50 other warbler species) … … and the Arctic Warbler (or maybe some other warbler looking very similar). Daniel Gustafsson and coauthors looked at chewing lice of the Grey-headed Lapwing.
Geological Survey, a massive scientific research agency which studies America’s natural resources and anything that threatens them, like climate change. Fish and Wildlife Service, as well as overseeing all federal lands managed by the Bureau of Land Management, and presiding over the U.S. The fight to protect ANWR has been an uphill fight.
