Green-rumped Parrotlets: from egg to adult Text and photographs copyright Nick Sly (except Rae Okawa where indicated) and are used with his permission. Getting intimate with a species over the course of the breeding cycle is one of the more rewarding aspects of birding, and field research too.
The Latin species name alphonsiana refers to Prof. And its eBird description as a “large and spectacular pheasant”, which – you guessed it – probably refers to the male. In one group, they added a blue egg to their nests. In the other, they added both such an egg and a peanut half-shell.
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.
In California, coveys break up and pairs begin forming in February or March, followed by nest building and egg laying in May or June. She will usually lay 12 to 17 eggs, averaging five per week 1 , before beginning incubation. Occasionally, larger clutches occur due to egg dumping by other females. References: 1 Baicich, Paul J.
They may be about bird eggs ( The Most Perfect Thing: The Inside (and Outside) of a Bird’s Egg , 2016), or a 17th-century ornithologist ( Virtuoso by Nature: The Scientific Worlds of Francis Willughby, 2016), or How Bullfinches learn songs from humans ( The Wisdom of Birds: An Illustrated History of Ornithology. Beagle , pt.
And of eggs and nests and birds on nests. She does, and her narrative serves as a role model for how to write about birds simply and knowledgeably; informing birds’ family stories with scientific facts and research findings. Cedar Waxwings exchange berries, carry nesting material, eggs. And of birds courting and mating.
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.
This laughingthrush is a cooperative breeder – nestlings are fed by all members of a group, often 6-12 (not just 2 as in Wham!): “A female may share a nest with another, and 3 or more adults may take turns incubating the eggs and feeding the chicks.” ” ( source ). The male is, indeed, rather a handsome Thrush.”
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.
An impressive combination of research and artwork, combined with a pragmatic organization aimed towards quick identification, and education, Baby Bird Identification extends the frontiers of bird identification guides and is an important contribution to wildlife rehabilitation literature. Comments from more experienced readers are welcome.).
Isla Rasa was declared a sanctuary in 1964, and egg-collecting and disturbance during the breeding season are discouraged. It’s all of the things I learn about different birds from researching to write posts. References: 1 Birds of North America Online , 2 BirdLife International. www.youtube.com/watch?v=FUBX_tlHySc.
When we come to Gentoo Penguin again in the South Georgia chapter, for example, we’re referred back to its first appearance in Antarctica, utilizing the outline numbers.). Noah Stryker wrote about his experiences doing research with penguins in Among Penguins: A Bird Man in Antarctica (Oregon State Univ. Press, 2011).
They have special adaptations to stay warm and to keep their eggs and chicks warm. This separation of different traits into individual and separate histories, each with its own selective environment, is now known as “mosaic evolution&# in reference to a mosaic showing a coherent picture, but made of many individual separate tiles.
A few weeks ago, when we traveled to Guadalajara, Mexico, I researched the many different species, especially the hummingbirds. In doing some research on the Motmot family, I found several references to the fact that the long decorative tail is actually quite fragile. Their food consists of insects, small reptiles, and fruit.
Or, Pygmy leaf-folding frogs, Afrixalus brachycnemis, from Tanzania, tiny climbing frogs who lay their eggs in leaves and then fold the leaves over them for protection, sealing the nest with secretions. The male and female position themselves close to each other, on top or in back, so that the eggs are fertilized as the female releases them.
They breed in dense colonies, incubate their single egg on the feet, and take more than a year to fledge a chick. This is not unusual for some types of reference books, but in the birding world, where we refer to our guides by the name of the author, we want a little more information.
Birds are able to fly away, but their nests and eggs can be destroyed. Forest Service research biologist Vicki Saab studies, birds evolved alongside fire and flee in the face of conflagrations. References: 1 Proceedings of the National Academy of Sciences. Fire can also cause wildlife to be burned, dehydrated and malnourished.
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. A breeding bird atlas is a special kind of book. Corey did just this in this 2011 posting about Vesper Sparrow Pooecetes gramineus in New York State.
He pairs conventional wisdom with actual research on such wisdom and speaks to experts who’ve been pondering the issues from the perspectives of their various disciplines. 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.
The Peterson Reference Guide to Sparrows of North America by Rick Wright is different in approach from any other bird reference book I’ve used, bursting with expertise about sparrow identification, history, and taxonomy, and profusely illustrated with photographs by Brian E. Small and other photographers, mostly, if not all, birders.
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!)
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.
One proposed explanation by the researchers for this phenomenon is that similar-looking birds reduce their risk of predation, as predators find it more difficult to focus on and isolate a single target. Interested in doing research on the Orange-bellied Leafbird ? Interested in doing research on the Orange-bellied Leafbird ?
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
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. They are by Karlson, from his years as a research biologist in Alaska, and Ted Swem, a U.S. Dunne and Karlson live and work in Cape May, N.J.,
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.
Most of this book is about Eurasian Wryneck, as the subtitle indicates, though Red-throated Wryneck is referred to throughout and there is a chapter focused on the species. Gorman’s personal field experience informs much of the text and his total grasp of the field means he relates one research finding to another with narrative ease.
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. So, you’re not always sure if the text is referring to the turtle in the image. The captions use common names.
The photographs are from VIREO, the ornithological image collection associated with the Academy of Natural Sciences of Drexel University, which licenses bird photographs to many guides and reference books. I am particularly happy to see that the bird communication section includes recent research on singing female birds.
Unfortunately, this woodpecker seems to be even less researched than the previous one. Research required to determine its feeding ecology and breeding biology.” ” And why not. The same observation also proved a possible life span of this species of at least 14 years. ” “Habits not well known.”
The nickel was placed in the nest for the photo to show me the size of the egg for identification purposes, then removed. Even though the female lays only two eggs per nest attempt, they enjoy a protracted breeding season in which multiple nesting attempts can occur every 30 days, and in Southern locations, nearly year round.
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. A longer reference list that includes scientific articles can be downloaded from the Princeton University Press web site. With odonates, there are always exceptions!
Apparently, she supported the research of a Romanian team on ectoparasites of birds from Meghalaya (India) – and for her troubles, the team thanked her by naming a species of feather mite newly discovered on Large Niltava after her. Maybe doing ornithological research was just his way of compensation.
The team explored Nevada and Utah, with Ridgway collecting thousands of bird specimen, plus nests and eggs for the Smithsonian. He ended up producing THE standard reference for anyone who was involved in a profession or passion that involved color. He wanted to create color standards to describe birds.
” Interestingly, the authors don’t attempt to give full descriptions of species, referring the user to the guide’s illustrations and the encyclopedic Handbook of Australian, New Zealand, and Antarctic Birds (which several of the authors also worked on). Subspecies are described under “Geographic variation.”
The Nonggang Babbler ‘s claim to fame is having only been discovered in 2008 (as a meaningless reference, it should be added that the first iPhone was released in 2007, one year earlier). Spot the reference? ) One of the reasons for birders to come here is to see the Nonggang Babbler.
How many eggs did a pigeon lay? He reasons out answers to both questions, finally stating that, despite what many eyewitnesses wrote, the birds had to have laid more than one egg and that the birds had to have nested more than once a breeding season. This is not that kind of book, as Fuller makes clear from the beginning.
Like a bad boyfriend not changing into nicer clothes for an evening out, the Brown-cheeked Fulvetta gets chided on eBird for not making any efforts: “an unapologetically drab and unmarked fulvetta” The Chestnut-headed Bee-eater apparently digs nest-burrows in which to lay its eggs. “It is not deep enough yet!
He always refers to himself and his wife and his child as "vegetarian." 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. In all fairness, most people's only reference is PETA. He never says he is.
In a blog post for The Daily Egg , Smith references a bar chart from HubSpot depicting the various sources of companies’ leads. Latane Conant refers to companies’ unidentified prospects as “the dark funnel.” The mix includes trade shows, direct marketing, social media and other usual suspects. The dark funnel.
This is a comprehensive, handsome reference book that is likely to become the standard for many years. I also enjoyed the breeding photo series, showing Downy Woodpecker eggs and then hatchlings within a breeding chamber in a tree, with only a few wood chips to support them. The taxonomy is tricky, as Gorman notes in the introduction.
“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.” ” (Tim Low, “Where Song Began”). While this may sound attractive at first, it also covers highly immoral behavior.
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. Oh, and if you want to impress someone or talk to an ornithologist about it, make sure to refer to it as sexual dichromatism. They will love you for it, I promise.
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.
