Whittaker’s adventures in olfactory research take unexpected turns into genetics, chemistry, and the halls of academia. One of Whittaker’s first experiments was to place other birds’ preen oil on the nests and eggs of Dark-eyed Juncos. ” (p. 241) that contribute to a bird’s odor.
As a Northeast birder I am familiar with the alarming decrease in the number of Red Knots along Atlantic shores and have signed petitions and written e-mails calling for legislation and rules that will limit the overharvesting of the horseshoe crab, whose eggs Red Knots depend on. million in the late 1990’s. Should the gulls be controlled?
A logical and outstanding successor to The Genius of Birds (2016), Ackerman’s award-winning book about bird cognition, The Bird Way explores the diversity of bird behavior, the norm and the extremes, with an emphasis on cutting-edge research and findings that explode assumptions. Yet, the research projects are never the whole story.
Photo of Common Cuckoo by Flickr user jamalhaider There is some interesting new research you will want to know about concerning Reed Warblers and Cuckoos. The famous bird experts, Thorogood and Davies, carried out an experiment which… reveal that social learning is specific to the cuckoo morph that neighbors mob.
It's in response to the arrest of Yale animal technician Raymond Clark for the murder of Annie Le, but makes some important points about animal research. There's a reason for the security that keeps Beagle burn videos from surfacing like egg farm videos. At a tax payer cost of $472,370? Even as his colleagues scoffed?
Barker, and Carroll Henderson is a well-researched, copiously illustrated, engaging study of bird feeding practices, personalities, inventions marketing, and companies that developed in the United States from the late 19th century to the present day, with a little bit of Canada, Europe, and South America thrown in. Baicich, Margaret A.
And summary and discussion of recent research on how birds have changed the frequency and pitch of their songs in response to human noise and the possible consequences of those changes (again, we know that we don’t know). I do wish there was more about research on female bird song. And, that’s it.
Among birds the Egyptian Vulture uses rocks to crack Ostrich eggs, the New Caledonian Crow and Woodpecker Finch (one of several Darwin Finches of the Galapagos Islands), uses sticks to extract grubs from inside a branch. Further support for inherent behavior comes from experiments. The use of tool by animals is surprisingly rare.
He draws on his personal experiences to inform the history, geography, and especially the travel option sections. A lot of his travel experiences involved camping and independent travel on small sailing yachts, and if this is your preferred mode of travel this book will be particularly useful. Press, 2011).
Spending days searching for an elusive bird you finally get to see, a bird that few others have seen, a bird about which very little is even known, and then seeing it is a tremendous and unforgettable experience. Clutch size, incubation period, time to fledge, and eggs are all undescribed.
For decades researchers have made annual trips out to the Tortugas to catch Sooty Terns, attach tiny silver bands to their legs with unique identification numbers, and then set them free again. Throughout the next three full days I would experience all of the jobs that go along with proper bird banding.
For birders, it’s the extremely large book, shelved in a place where it can’t crush the field guides, used to research the history of a bird in their area. And, if you are part of an ongoing atlas project in your state, tell us about your experiences. A breeding bird atlas is a special kind of book.
Where does the female Emperor Penguin go after she has produced that one egg and handed it over to the male for incubation? This is essentially a survey of ornithological marine research told in the voice of one of its most passionate and experienced participants. Technology to the rescue!
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.” Women who like jacanas will probably also like Spotted Redshanks. But maybe that is actually a good thing.
Over at Animal Rights and AntiOppression , we’ve been discussing tactics and sharing our thoughts and experiences about what works and doesn’t work when it comes to advocacy. The research, much of the time, doesn’t support the conventional wisdom (which is not to say the case is closed on any issue). All day long.
Given my west coast experience, I have made dedicated birding trips to several of the more predictable birding hotspots. I mention these trips because, along with other trips and experiences closer to home, they inform my research into my future birding travel. Geography is destiny.
This is the story of Fox’s experiences on board the Achiever, the research vessel of the Raincoast Conservation Foundation. It’s a small group of 10 to 12 researchers and crew members, and Fox is the sole person responsible for the bird surveys. Northern Fulmar, image courtesy of Peter Hodum.
The top three things that you need to do are; Experiment. Experiment. If you do not know what to try just research forgetting about your serious side and, you will be surprised at what ideas will come your way. Do not place all your eggs in one basket. So, we need to bring this change into our marketing concept.
But then again, it could be due to the fact that we are constantly bombarded with billion-dollar advertising campaigns from the meat industries, the dairy industry, and the egg industry, as well as from myriad restaurant chains that promote and sell these very animal products. It could be "our little snake brains," as Ausubel suggests.
As we know from the French documentary La Marche de l’Empereur ( March of the Penguins) , the females skedaddle from the breeding colony once she produces an egg, leaving the egg to be incubated by the males, who fast for 120 days while keeping the egg in a flap of their feet. (I
Hauber Hauber’s mini-essays focus on specific behaviors, enhanced by references to recent research yet written in a relaxed, personal way. Hauber is really good at presenting scientific findings so they don’t seem scientific at all, simply reasonable answers to our questions. Mark Hauber is currently (just appointed!)
It’s the warbler that is often the last unchecked species on birders’ life lists and, whether you list or not, for most of us observing it is a once in a lifetime experience. A nest wasn’t found until 1903, which set off a craze for Kirtland’s Warbler skins, nests, and eggs. Now there are volunteer guides, tours and a local festival.
It’s a book that counterpoints and combines facts and personal experiences, science-based and eloquent writing styles, textual description and visual information, a history of abundance and an uncertain future. They are by Karlson, from his years as a research biologist in Alaska, and Ted Swem, a U.S.
He also believes that we are living in an era of incredible scientific research, one in which new genetic technology and findings from diverse scientific disciplines have turned assumptions upside down, opened up new lines of thought, and provided answers, or at least probable answers, to many of our questions about why birds do the things they do.
Females seem to be the only sex to sit on the eggs according to literature, but no research appears to have been done on the night time routine. Female Red-capped Plover on nest in jogging area Another nest was in the higher area behind where vehicles access the beach and despite the odds the eggs successfully hatched.
.’ Gorman has read and distilled probably every research study ever written about Wrynecks or related to them; my quick count of the citations in the 16-page References section came to 295. Practically every sentence is documented with these studies. Yet, The Wryneck does not read like a literature review.
The island is teeming with so many birds that their eggs and young chicks were once harvested for food. Northern Gannets on cliffs Dense Northern Gannet colony While researching this trip, there was a common theme in the articles relating to the gannets: Avian Flu hit this colony hard in 2022.
Of course, it is hard to resist looking at a paper titled “Host personality predicts cuckoo egg rejection in Daurian redstarts” Basically, the personality of a female redstart (bold or shy) predicts the responses to parasitic eggs – bold hosts are more likely to reject parasitic eggs. Not this one though.
Birders are always happy to see a turtle or tortoise, and there are times of the year when my social media feeds are sprinkled with photos of turtles beings removed from roads or crawling to land to lay eggs. Lovich and Whit Gibbons bring decades of research and experience to this book. On the positive side, authors Jeffrey E.
Experiments in the field (the famed Asa Wright Nature Center veranda) involving Bananaquits and bananas came up with numbers ranging from 7 to 16, but a tanager always came along to interfere with Bananaquits’ noisy appreciation of their namesake fruit. (2) Which hummingbird was more beautiful—Tufted Coquette or Ruby-topaz Hummingbird? (3)
Today, we know a little more, such as the fact that an eagle couple produces one egg every two years, but numbers remain low, too low. And, he tells us about the time he was attacked by a parent Philippine Eagle as he handled an egg at the nest, hundreds of feet above the ground. This film could not be made without them.
The majority of wildcats live today in Africa, and virtually none of them have provided the DNA from which supposed histories of domestication have been constructed by researchers. I new him because we enlisted his Dryfus Lion and one of his tigers to carry out experiments with bones (this is something archaeologists do).
Her experiences are framed within the larger scientific histories how once common species become endangered, and of how people and organizations have strategized and explored controversial paths to bring their numbers up and nurture them till they fill our skies. Endangered. Extinction. Conservation.
Bolivar Flats Shorebird Sanctuary was an amazing and unexpected treat, but that’s because I failed to do my research. It’s only 15 minutes north of High Island, though in neighboring Chambers County (High Island is part of Galveston County, good to know if you’re going to be researching eBird checklists).
And, in a very lovely section in the middle of the book, she describes the life cycle of the cahow, informing evocative passages about their nocturnal courtship and flight with recent research findings about how seabirds are able to function—eat, sleep, navigate home. These are magical experiences.
I know from experience how accessible Dennis is, last year he helped me identify a damselfly I photographed in Costa Rica (Argia anceps, no common name). Common and differing traits will include type of coloring, thorax patterning, how they perch or fly, how they copulate, and how they oviposit, lay eggs.
In the slightly frighteningly named journal “Science of The Total Environment”, there is a paper on organochlorine compounds in Purple Heron eggs nesting in sites located around a chloralkali plant (Ebro River). Summary result: relevant chemicals emitted by the plant can be found in the eggs. Bye, bye, Lesser Coucal.
Fortunately for the honor of the species, the researchers found that kleptoparasitism was practiced at a low rate (4% of observations) while much more often, drongos captured insects disturbed by other species (41% of observations). My cats refuse to even try Fiery Minivets.
Illustrations were created using diverse visual and physical source materials–skin collections from Australian museums and a database of over 300,000 photographs (plus, of course, the artists’ years of field experience). Some offer nest information, egg information, breeding timeline, in flight views, etc.
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. Again, Cade led with solid evidence acquired through his own research. It was there where the first glimpse of his future began.
In some species accounts, notably Song Sparrow, this text reads as a carefully researched, finely detailed ornithological/historical essay. And, the 1996 volume includes information on nests and eggs, a topic not covered by the Peterson guide. He has an academic background in German and medieval studies, including a Ph.D.
This species seems to frequently join mixed-species flocks – in research in Thailand, the species was found in 20% of the mixed-species flocks. One was reported to have raided the nest of a Grey-throated Babbler , eating at least two eggs and possibly one nestling ( source ). On the plus side, it looks rather funny when wet.
Yet he spends time describing the miserable deaths of day-old male chicks and understands what happens in dairy production, and I assume he doesn't partake of anyone's eggs or milk. I have a difficult time understanding how someone has reached that conclusion after so much deliberation and research. But why does he say "vegetarian?"
Researchers have also learned that the cancer-causing chemicals that form in beef as it cooks also tend to form in chicken. Sadly, Gillette's experience is not unique. Unfortunately, switching from red meat to chicken does not help very much. Meatless meals also help your child to keep stronger bones. But what about prior to two years?
