It didn’t occur to me till I started reading The Falcon Thief: A True Tale of Adventure, Treachery, and the Hunt for the Perfect Bird that there was also a possible threat to the eagle herself: poachers, who steal raptor eggs and chicks. McWilliam realizes he’s dealing someone special, a career falcon egg-thief.
The eBird cartoonists call the Spot-breasted Parrotbill a “bulbous-headed brown bird with a comically large bill” As a foreigner living in China and thus used to having my nose size ridiculed, I definitely feel with the parrotbills. In one group, they added a blue egg to their nests. What a pity.)
is like this: meticulously researched, densely illustrated, and designed for non-linear reading. That initial simplicity transitions to detailed spreads where Ignotofsky manages to weave in definitions of bird terms like “altricial” and “rachis” and “chalaza.” And What’s Inside a Bird’s Nest? What’s Inside a Bird’s Nest?
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. Whittaker’s research road is more serpentine than most academics.
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. If birds don’t want to be handled, then they definitely didn’t want to be weighed. Sooty Terns are incredibly birds.
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!
Another puzzling thing to me, as for me, the ideal number of people to live with would be somewhere between zero and one but definitely not above 1. According to the HBW, when breeding, male birds do most of the incubation and parenting while females often leave the nest up to one week before the eggs hatch. End of side note.
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.
These fossils are seen as proof that some dinosaurs brooded over its eggs. And, he places current research within a framework of paleontological history of intrigue, backstabbing, and name-calling feuds. (No, Like birds. Don’t let the university press imprint deceive you.
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.
Well that depends on several factors, the most important of which are the definitions of the terms “remote” and “endemic” My subjective thoughts on remoteness are that the term should be defined by two factors: 1. How difficult is the place to reach in terms of planes, trains and automobiles?
Once a body of research was established and the bird was declared endangered, it took many more years of experimentation, political maneuvering, conflicts with the National Guard, and some tragic fires to establish what is now acclaimed as a model conservation project. Now there are volunteer guides, tours and a local festival.
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.
Once the egg has been laid, the female is chased away and the males hatch it.” Other research (cited on the rather straightforwardly named website www.genderinclusivebiology.com) found that 80% of gay swan couples successfully fledge their young, compared with only 30% for straight couples.
The first two questions were never definitely answered. A little bit of research when I got home unraveled the ways of publishers here and in Great Britain. The accounts aim for specificity and authority; dates and locations of rarity sightings are given, and research articles on nesting and behavior are cited.
It definitely was a small dragonfly, and all photos show it with flat wings. 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. I am sure my dragonfly friends reading this review will not fail to tell me if I am wrong and why.
I am particularly happy to see that the bird communication section includes recent research on singing female birds. They expand the definition of this book from identification guide to avian reference book. Plate 28 from Audubon Bird Guide, Eastern Land Birds, by Richard H. These are all informative and current.
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.
The babies that hatched from these eggs were released on Florida’s east coast. April 14, 2012 Liquid oil still seeps from some Louisiana marshes and ongoing research of toxicity levels is being conducted by LSU researchers. The visibility of the BP oil spill might be blurred but it is definitely not forgotten.
So, I was very excited when I heard that Rick Wright was writing a book about sparrows, the first treatment of North American sparrows since 2001, possibly the first book about sparrows of North America, depending on your definition of that geographic area. He has an academic background in German and medieval studies, including a Ph.D.
“A reading of recent research shows that Australian birds are more likely than most to eat sweet foods, live in complex societies, lead long lives, attack other birds, and be intelligent and loud.” If I ever have a used car I need to sell, I will definitely ask for their help. m, individuals feeding on bread were only 0.25
Take a look at this little Blue Tit and admit that you have never seen a more pathetic picture of a bird that combines the colours blue, yellow, green, white, and black in the most marvellous way you have ever seen: Recent research has shown that Leonardo da Vinci showed a Blue Tit to his model while he painted the smile on “Mona Lisa&#.
Here’s a high definition, high speed video of a Muscovy penis popping out: So, why would a male duck need such a crazy appendage that works at lightning speed to mate with a female? Like any healthy bird, she wants to make sure that she gets the best of the best when that appendage fertilizes her eggs.
For example, a researcher and presumed ornithologist set out with two hypotheses related to the Ashy Drongo (and another drongo species) and wrote a paper about it. If you do not know what USP means, you are definitely not a marketing person yourself.
This may have been partly a leftover from the Victorian fascination with egg collecting (the infamous passion known as oology), but probably more from people’s burgeoning interest in the nests and eggs found in their gardens and fields, gateway artifacts to a newer hobby called birdwatching. The Harrison guides are out of print.
The most likely explanation – as judged by the authors – is something called the farming hypothesis, which states that brood parasites such as the koel may deliberately destroy nests as it gives them a good chance to deposit an egg in the replacement clutch. Me, definitely not).
If the male’s color fades after the first egg, the female reacts by laying a smaller second egg – seemingly deciding that it is better to cut her losses as the male apparently is the avian equivalent of a deadbeat father. Are these the paper mills one occasionally reads about in relation to Chinese research papers?
To be honest, both the robin and the flycatchers shown above remind me of the easter eggs I hunted for as a child – the same strong colors in front of a green background, same time of the year (feel free to insert your own Proust Madeleine reference here) … Bluethroats apparently are good at imitating other birds.
Given the complexity of the research, the result feels like a bit of a letdown – “northern populations start migration earlier than southern populations, especially in autumn” The species name of the Chestnut-eared Bunting is fucata , from the Latin “fucare”, to paint red. Better safe than sorry.
I have written about the interesting sex life of these jacanas a few times already (short version: female mates with male, lays a bunch of eggs for him to incubate and raise the chicks, leaves him, finds another male, repeat). Apparently, after a male first mates with a female, he throws out the first one or two eggs she lays in their nest.
