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! From Science Daily : Crows have the brain power to solve higher-order, relational-matching tasks, and they can do so spontaneously, according to new research.
The wood stork occurs and breeds in Central and South America. I have seen them foraging on sandy shores of rivers deep in the Amazon, enjoyed them in their raucous breeding colonies in the Everglades, flushed them out of canals during walks around my house, and perhaps more importantly contribute to their recovery. Photo: U.S.
It could easily be mistaken for a book about aviation or space navigation or even a flight simulator game if you don’t read the long, adjective-filled subtitle: How a Passionate and Quirky Group of Pioneering Scientists Solved the Mystery of Bird Migration. THIS IMAGE NOT IN THE BOOK. Schulman, 2023.
And much of that time is spend loafing around the breeding colonies trying to pair off and engaging in silly-looking behaviours referred to as dancing by scientists. It can take over a year to raise a chick for the larger species, and even species that can fit their entire breeding cycle into one year tend not to breed in consecutive years.
Do it for science! Snowy Owl being harassed by an American Crow. Will you put up $20 to make this irruption meaningful in a scientific sense? If 150 of you do that it would already be enough for a transmitter! Donate now to Project SNOWstorm ! Do it for Bill! Do it so Snowy Owls get nice warm beds in a hut in the woods! (OK,
DNA evidence then indicated that they are an ancient group mostly closely related to the bizarre and wildly different rockfowls and they were therefore contentiously placed in the Picathartes family, before finally finding a contented home in their own family, Chaetopidae. A dancing Blue Crane , South Africa’s national bird.
Here’s a diagram, available on the Audubon site , that compares its 2000 range with its anticipated 2080 range: Only 1 percent of the bird’s breeding range remains stable between 2000 and 2080 if global warming continues on its current course. … Conservation Audubon endangered species Extinction Week longspurs science'
Depending on your particular interest, opt for March/April (spring migration), May/June (breeding season), August to October (autumn migration), or November/December when waterbird migration reaches its peak. Raphael Nussbaumer is a keen ornithologist who enjoys combining his passion for birds with computer science background.
Every spring, billions of migratory songbirds in Europe fly north to their breeding grounds. Several months ago, a group of bat researchers spent the night recording the sounds of a marshy Spanish forest. A group of researchers at the N.C. Museum of Natural Sciences and N.C.
Erika is a first year graduate student studying Ecosystem Science and Conservation at Duke. The park is home to not one, not two, but large three colonies of breeding seabirds: the Brown Noddy , Magnificent Frigatebird , and Sooty Tern. Lots and lots of birds. It was for the birds that we made this journey in the first place.
And, as I have mentioned before , under-birded countries like Mexico provide lots of opportunities for amateur birders like me to make real contributions to science. The photo also illustrates how our drought affects two groups of resident and wintering birds (which number in the hundreds of thousands). But obsessed I am.
Quite likely, these birds are also the inspiration for Australian science communicator Dr. Karl Kruszelnicki. Within group, all males copulate with all females.” ” Like many Australian birds, they breed cooperatively with a varying number of helpers, often siblings or older offspring. ” (HBW). ” (HBW).
Interestingly, the molt of the males takes about 20 days longer than that of the females – the authors speculate that this is because of the different peak time efforts in breeding, with the males being involved earlier (singing, establishing territory) than the females (incubating, nestling care).
I would never have believed it, but if the science says so who am I to argue otherwise? But it seems sort of appropriate in hindsight that a family so strange would end up alongside a similarly unpredictable group of birds in the flamingos. But that’s a group for a different time. Horned Grebe , photo by Julie Gidwitz.
Seabirds are one group of birds that go for the latter strategy. Others, like the petrels and some of the auks, will lay a single egg per breeding attempt. The investment placed in each clutch bur seabirds is so great that only one breeding attempt can be seen to completion each year.
My feelings about shorebirds came back to me a few days later, as I observed a mixed group of peeps and Dowitchers at Mecox Inlet, eastern Long Island, not far from where Peter Matthiessen once observed the shorebirds of Sagaponack, the stars of the first pages of his classic The Shorebirds of North America (1967). my face betrayed me. “I
The first shorebird arrivals are apparently birds that failed at a breeding attempt and don’t have time to re-attempt; they might as well head south early. This is by no means an exact science. I have Facebook friends and belong to multiple bird related Facebook groups throughout South America. The fall migration is underway.
This is a very different book from what I expected, less of a handbook and more of a comprehensive identification text on 24 groups of birds, presented in words and photographs. These are bird groups that have been covered extensively by other guides. Armistead and Brian L. It is an intriguing choice of species.
Each account contains a range map created by Weidensaul, utilizing diverse sources–breeding bird atlases, banding data, research articles. (It A group of owls is traditionally called a parliament, though there is a line of thought that C.S. Lewis originated the term as a pun on Chaucer’s Parliament of Fowls.
And they were intrigued and they had questions, lots of questions, more questions than could be answered by a field guide or a social media group. Each spread consists of a full-page painting of a bird or group of birds on the left and a combination of text and illustrations on the right. copyright @2020 by David A llen Sibley.
Within species, or closely related groups of species, beaks vary by small amounts that result in important adaptive fine tuning, as we see in the Grand’s studies of the Galapagos Finches; Beak related behavior is at the cutting edge of survival for many bird species. Well, maybe a little better than that but not much. Here’s the thing.
One website states that only 15% of the birds that hatch make it to become first year breeding adults, 6% make it to the second year, and 3% to the third year. Other species – such as starlings or t**s – stealing the nesting site of Eurasian Nuthatches is one of the major reasons for breeding failure.
From the Science Insider. Instead, DeMuth will plead guilty to conspiring to damage a Minnesota company that breeds ferrets. DeMuth studies radical activist groups, and he argued that forcing him to break confidentiality agreements with his subjects would constitute a violation of his academic freedom.
So, I anxiously followed the “Flock to Marion 2022” Facebook group in anticipation for open cabins to come up for sale. These have been used by meteorologists, technicians, and researchers who spend about 13 months on the island at a time researching a variety of sciences. I waited…and waited…and waited. and seabirders.
I started to learn how to tell waders (and gulls) apart only when I locally ran out of other hard bird groups to tackle. Quarter of a century later, I jumped at an opportunity to study environmental sciences, and guess what awaited me there? And it wasn’t so long ago. When there was hardly much else left, I accepted the shorebirds.
Data were collected from the North American Breeding Bird Survey and the Pan-European Common Birds Monitoring Scheme. I want to alert you to a recent study (from April) that looks at the plight of bird populations under conditions of climate change in Europe and North America. Stephens, Philip, et al. 352:6281(84-87).
In the non-breeding season, male Baya Weavers sometimes enter the basket-making trade, often with considerable success. Meanwhile, the females seem to have a much more relaxing life, at least in this early stage of the breeding season. It very effectively forms a small foraging group in this manner. You can see why here.
This may be surprising in a group of birds that – let’s be honest here – all tend towards the drab, but the Marbled Murrelet was not named for its luxurious bathroom finishes. Some murrelets are named for their styling. The Long-billed Murrelet , well. The Japanese Murrelet , well. So there you have it.
They used Great T**s from non-urban and urban areas, and mixed them up through breeding, to rule out any possible family history of telomere length. The benefits are many, including the availability of anthropogenic food sources, breeding boxes and warmer temperatures. Another group simply heard adult songs played through a speaker.
If migration evolved many times in birds, then it would be worth asking if it evolved in birds more often than in other groups of vertebrates. Loons hardly ever fly when they are on their breeding grounds or their winter-water, but the migration is for many loons a non-trivial distance. Consider the implications. 2 PIERSMA, T.,
Working at zoos as curators where they are responsible for acquiring animals, either through buying them from other zoos or overseeing breeding programs. Working as an animal science researcher at colleges or universities. Monitor animal behaviors• Groom and exercise the animals• Speak to visitor groups about the animals.
Written in a friendly, inclusive style quietly grounded in science, How to Know the Birds is an excellent addition to the growing list of birding essay books by talented birder/writers like Pete Dunne and Kenn Kaufman. ” The essays are arranged in thematic order grouped in six sections: “Spark Bird!”
The science currently believes that up to twenty five percent of the coral on the Great Barrier Reef could be lost to bleaching in the next forty years. Of the twenty six Sooty Oystercatchers fourteen were first year birds and would have moved to the mainland with the non-breeding flock during this time of year.
It is also familiar at inland sites in winter, especially reservoirs and refuse tips, and breeds in the relatively-Northerly regions of Europe, Asia, and North America. Yellow-Legged Gull These gulls breed around the Mediterranean and have yellow, rather than flesh-coloured legs. Get yours today!
Woodward’s Barbet belongs to a group of barbets known as Green Barbets. Durban museum based ornithologist Philip Clancey took numerous expeditions into Zululand and Mozambique, discovering several new subspecies as well as a new species to science, Lemon-breasted Canary in 1961.

For those who didn't read the five-part Slate series " Pepper, the stolen dog who changed American science " by Daniel Engber , I recommend it for the history, but also for the misconceptions and assumptions that you might want to discuss on the Facebook discussion about the series. Let's deconstruct: Part I: Where's Pepper?
They reach breeding maturity at four to seven years of age, produce only one chick per nesting season, and only one in three offspring survive to fledging age. Ohio has tracked two families of their state-endangered breeding sandhill cranes and found them to have wintered over in Tennessee in 2010. Lots to think about.
The source of this ranking, BirdLife International, lists Bolivia as currently having 1,439 bird species, including 18 breeding endemics. This is more than eBird reports–a checklist generated from the citizen science database lists only 1,413 species. Clearly, this is an under-birded country. .
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. Color-coded page headings denote bird groups, matched by color-coded bird silhouette icons located midway down the edge of the page.
Let’s hope it can find some relatively unfragmented habitat for breeding – studies show that the failure rate of nests is much higher in fragmented habitats. ” That is why cross-country pairings among this species are almost never successful. The eyes make the Arrow-marked Babbler look a bit like a serial killer.
Supporting local conservation organizations and participating in citizen science initiatives allows us to contribute to the protection of Shanghai’s bird species and their habitats. Many native bird species have been displaced or lost their breeding grounds, leading to a significant decline in their numbers.
I am not sure about the security situation in Iraq these days but at least some people do ornithological research there – resulting in papers such as one titled “Breeding observations of the Black-winged Kite Elanus caeruleus (Desfontaines , 1789) in Iraq” Impressive. Fortunately, they are quite common in Shanghai.
Poor researchers Nicola Coumi and Rob Slotow failed to find anything particularly interesting about vigilance in Bronze Mannikin groups. Greater Flamingos are considered cooperative breeders as fledglings are raised in a creche, in which large numbers of young are watched by multiple non-breeding adult greater flamingos.
Scientists were largely limited to studies birds in breeding colonies, at least those we knew about and that were accessible (and, if you think that’s a complete list, you haven’t read the news that came out this week about a new colony of Adélie penguins found in the Danger Islands, Antarctica). Technology to the rescue!
