Researchers say that South Georgia Pipits have hatched chicks. That’s because these birds won’t breed when rats are around. And let’s face it, would you go to all the effort of breeding if there was a hefty chance that your newborn would just go down some invader’s gullet?). Image above by Brian Gratwicke/Wikimedia Commons).
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.
Let’s say you’re a bird wrapping up your breeding season in the north of Scotland—where do your thoughts turn when winter beckons? The researchers theorize that these birds might not be strays from the Scandinavian Phalarope population, but instead perhaps originally from North America. Photo by Adam Rowlands/HEMEDIA.
And now we get to the part of the post in which I briefly and unscientifically mention a few research papers on the species to have a reason to post a few more of my photos. It seems the paper is on the effect of swan feeding and swan movement on the release of nutrients, but given the language, I cannot be too sure about this.
I teach human evolution, and at some point I use a chart showing reversals in the Earth’s magnetic field, which in turn relates to how we date some ancient sites. Birds Navigation Olfaction research Sheawater' The photograph of Cory’s Shearwater is from this blog post.
According to Wikipedia, these birds are good at multitasking, being “in some parts of its range … known as a symbol of luck, longevity, and fidelity” As in humans, “the social implications of dancing [among the cranes] are complex in meaning” ( source ). It seems that two Italian men have found a way to do both.
Many of the great debates over human behavior, those related to things such as race or gender, are muddled and messy because plasticity is ignored. Plasticity in humans is probably modulated primarily through experience and enculturation. Presumably the humans keep away the predators. The paper is in Natrure Scientific Reports.
The breeding ecology of the Yellow-bellied Warbler was actually studied exactly here at Nonggang in 2019 by 3 Chinese researchers. Apparently, some bird photographers think that any human artifacts shown on a bird photo immediately spoil the whole photo. This included recording a total of 77,760 minutes of video.
You see, it clearly resembles a hybrid between the Spanish and the House Sparrow, and an ancient hybrid event was long suspected to be the source of its existence – with recent research indicating that apparently this isn’t the case after all.
Some remained stored for decades before a researcher would pick them up and inquired about these poorly documented specimens. After all, what was thought as its habitat was heavily deteriorated and converted to agriculture as the human population grew. This flock is composed of about 54 birds including nine breeding pair.
For example, years ago, Eiton Tchenrov postulated that the wild progenitor of the domestic dog, some subspecies or another of wolf, could benefit from overlapping its breeding territory with human hunters. The humans tended to keep away a range of predators that might take the pups as a form of interference competition.
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. Research done quite a while back suggests that this is adaptive.
Over the next few days, the Alpine Accentors ( Prunella collaris ) will arrive on their high-Alpine breeding grounds – it is time to start singing, despite that the treeless Alpine landscape is still under metres of snow. all Alpine Accetor photos digiscoped (c) Dale Forbes. all Alpine Accetor photos digiscoped (c) Dale Forbes.
It seems there is not much research done specifically on Blue-naped Parrots – the only paper I could find featuring the species was from 1981 and had the somewhat unappealing title “A Preliminary Study Comparing the Pharmacokinetics of Ampicillin Given Orally and Intramuscularly to Psittacines: Amazon Parrots (Amazond spp.)
Penguins are flightless, but some species locomote over long distances on antarctic ice to travel between breeding grounds and the sea. One part of this question can be answered with some very interesting recent research. They have special adaptations to stay warm and to keep their eggs and chicks warm.
(A press release about the study likened the contrast to “the differences between humans with and without freckles.”) On the opposite end of the spectrum is new research considering Yellow-rumped Warblers. Genetic-based research published in The Auk indicates that the four variants of “butternuts” include at least three full species.
Some uncountable species, like Mitred Parakeets , are in fact way more numerous than some of the countable species and they are clearly breeding in well-established populations. The population is not directly dependent on human support. I suspect that way more research and documentation is conducted on indigenous bird species.
Second, reading about birds courting and parenting brings out the tendency to identify, which leads directly to anthropomorphism, the tendency to assign birds human emotions and thoughts. Think of birds too much as humans and you lose the specialness that makes them birds. Some people love books like that. Yellow Warbler fledgling.
The length of each bird species account varies, depending on whether the bird is native or a “visitor” (the book’s term for migrant) or vagrant, breeding or non breeding. They breed in dense colonies, incubate their single egg on the feet, and take more than a year to fledge a chick.
Speaking of birds in nests, five Chilean Flamingo chicks who were raised by a human “surrogate dad” at a British wildlife center have now graduated to joining the adults in the center’s colony. The hope is that their presence while inspire the grown-ups to breeding success.
The task of wrestling this topic down into something that the human mind can manage, without losing sight of the big picture because it’s snowing in Buffalo, is likely to be the task of a lifetime for many science communicators. Few issues of our day are as huge, in scope or in implication, as climate change.
The newest bird on the brink to capture her fertile imagination is the California Condor, on which she graciously shares her research and ruminations: Sometimes as a writer you recognize there’s been something overlooked in your midst—something quietly abiding. Condors, like all New World vultures, can disturb the human psyche.
Fortunately for human males, the typical courtship of humans differs from that of the Coppersmith Barbets , which the HBW describes as follows: “When the nest is ready, the male may begin courtship feeding, offering fruit to the female. Some research topics seem a bit bizarre to me.
What I didn’t know was how this relationship actually works: the mechanics of Red Knot migration, the reduced digestive systems necessary for their long flighta, the need to fatten up quickly so they can fly to the Arctic and breed, how they compete with other shorebirds and gulls and, it turns out, humans, for horseshoe crab eggs.
The chance that this was a real Turkey are not great, and the chance that Columbus actually brought breeding stock from Honduras to Spain is not great, so maybe, maybe not. The history of the Wild Turkey, the reduction to its original range, and its re-expansion and re-introduction, remains today unclear and in need of further research.
The park is home to not one, not two, but large three colonies of breeding seabirds: the Brown Noddy , Magnificent Frigatebird , and Sooty Tern. 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.
I am sure some people will hate this photo of a Eurasian Hoopoe , framed as it is by human artifacts. As I am sure I have mentioned before, a lot of science work seems to aim to prove the obvious – though the researchers still phrase their results very carefully. Of course, me being me, this is a good reason to show it.
Scientific advances over the last three years have now made it feasible to easily tinker with rat genes, creating the possibility of far better models of certain human diseases, and potentially shortening the time it takes to develop medications. While both rats and mice have similarities to humans, rats win out in key areas.
Much like every beautiful sandy beach, the human encroachment is substantial. After several hours of research, my deep appreciation for this wonderful shorebird has not diminished. There is a warm little fuzzy feeling every time I get to see them, and especially this time of year, when they are their most vivid coloration.
But this breeding and social arrangement has its risks. For humans, you have the drama of sister wives. Newly published research in the journal Animal Behaviour suggests an ideal harem size for pheasants of 2.7 After all, variety is the spice of life, no? female birds for every male.
2 Responses to “Terrifying Truth about Crow Intelligence&# Jochen Mar 9th, 2011 at 6:09 am Their intelligence goes even further, and researchers have shown that Ravens master a feat that even 6 to 7 year old (human) children usually can’t accomplish: they can analyze what someone else knows / can know and act accordingly.
Specifically, the notice summarizes the long history of Hawaiian Goose conservation, including written recovery plans in 1983 and 2004 , implementation of those plans, and research, including a population viability analysis. Also, research filled in many knowledge gaps and informed conservation efforts.
No one in the room–neither dog nor human–can tell which cup hides the biscuit. Understanding a pointed finger may seem easy, but consider this: while humans and canines can do it naturally, no other known species in the animal kingdom can. “Humans are unique. Hare could run a very profitable shell game.
If I was an ornithologist aiming for a grant, I would now definitely highlight the need for more research on this topic. … Nest dismantling by the Hair-crested Drongo may be an adaptive behavior to increase fitness by reducing risk of future predation and competition for nest sites in the following breeding season” ( source ). .
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. ” I can see how this line of thinking leads to all kinds of sci-fi types of thought (“would I mate with an alien if I was the last human on earth”, etc.),
Data were collected from the North American Breeding Bird Survey and the Pan-European Common Birds Monitoring Scheme. In essence, the benefits to birds from climate change (global warming caused by human release of greenhouse gas pollution) is neutral, while the negative effects are serious and increasing.
At 9-10 months of age (or a bit later for large and giant breeds) feeding frequency can drop to once per day. Breed size. Smaller breeds have much faster metabolisms, and as puppies will require at least four feedings a day. Wet or dry? Owners often feed a mixture of wet and dry food to get the benefits of both.
Not to mention, its brilliantly bulbous crimson throat, bloated during breeding season must be a sight! However, the Stresemann’s Bristlefront is one of those birds that is simply enigmatic and rare and recently discovered, with many aspects of its life history unknown to humanity.
Cats are just as likely to get cancer, diabetes and organ failure as humans are. It is not transmittable to humans. Certain cat breeds have more complications than others. There are numerous things that your vet tells you to vaccinate for, but the worst problems often come from a poor-quality diet. Feline AIDS .
The archipelago consists of 17,000 islands stretching out over 2500 miles along the Equator with a varied history of avian research and study, most on the under- or not-studied side. With the advent of human development, we can now add “farmland and plantations” to various types of forest, rainforest, and swamps.
The Louisiana Black Bear (shown above) was listed as threatened within its historic range (defined as southern Mississippi, Louisiana, and east Texas) under the Endangered Species Act on January 7, 1992 (57 FR 588), due to extensive habitat loss and modification, as well as human-related mortality. The refuge is already open to sport fishing.
Both bushtit species occasionally are supported by helpers when breeding ( source ). Contrary to my usual habit, I will not try to transfer this finding into the human world as I am too afraid of being accused of fat-shaming. What do the males do while their partners are incubating?
And Sandwich Tern is Sandwich Tern, Howell finding the DNA research for splitting it “weak.” They also occasionally show breeding colonies or isolated populations, possible occurrences, and directions of range expansion. Fantasy is the key word here. Doing this work takes time! ” These are just some examples.
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.
