A UK government department had announced funding for a research project into the ‘Management of Buzzards to Protect Pheasant poults’ (poults are young Pheasants being reared specifically to be released for shooting). of nearly 500 radio-tagged releases).
It’s a bang-up breeding year for super-endangered birds! The species, which migrates from the Russian Arctic to Southeast Asia, is down to about 200 breeding pairs in the wild, due to habitat loss and poaching. For the past several years, getting the birds to breed has been an exercise in futility.
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. However, some swans claim that the views are much better in the highland habitat, and others are not that keen on raising chicks anyway.
Unlike Desi, the researchers involved don’t think the owls are curling up in a nice warm bed in a hut in the woods, but they don’t have much better answers than that, at least not yet. So they are raising money to buy more. Snowy Owl being harassed by an American Crow. That is where YOU come in! That is where YOU come in!
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. They are cavity nesters, breeding in natural cavities or holes dug into the soil. So why do it?
The breeding ecology of the Yellow-bellied Warbler was actually studied exactly here at Nonggang in 2019 by 3 Chinese researchers. Some Thai researchers looked at the breeding ecology of the Buff-breasted Babbler and published their findings in the somewhat unsuitable-sounding journal “Agriculture and Natural Resources”.
Thus, the cattle we raise for meat and dairy are sometimes called Bos taurus while the extinct wild form is always called Bos primigenius. Some time after the Spanish encounter with the Turkey, birds were brought back to Europe where they were raised and became an important source of food and fancy feathers. Which would be weird.
Some remained stored for decades before a researcher would pick them up and inquired about these poorly documented specimens. A captive breeding program was established with a facility at Gustavo del Solar’s property, not far from where the birds were re-discovered. This flock is composed of about 54 birds including nine breeding pair.
With birds bedecked in their breeding best and filling the air with song, this is migration at its loveliest. Threatened by loss of habitat both on breeding as well as wintering grounds, a few species have even become endangered or at least on a perilous track towards that worrisome designation. Ernesto and his team in the field.
But as I and others have said before, it does raise a very practical question about what field guides, which have for the most part been slavishly devoted to taxonomic order, are going to do. waters every year after breeding. The split is based on evidence of very limited gene flow between the populations despite geographic overlap.
Photo by Adam Riley (Rockjumper Birding Tours) Despite initial appearances, these birds are in fact very large passerines (13-16 in) and research has shown them to be an ancient basal offshoot from the passerine evolutionary tree. White-necked or Yellow-headed Picathartes, Bonkro, Ghana.
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.
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.
According to the McMurray hatchery , the “Silver Pheasant is considered a good ‘starter’ breed for people who want to learn more about raising pheasants” Hm. But then, would a lady pheasant be pleased to be described as “large”? What a weird world. Better watch them in the wild.
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. My first view of them was at a distance.
And apart from local people, primate researchers sometimes spot it, but it is a species seen by fewer than ten living birders. This book is essentially about those birds that breed on the continent south of the Sahara, a topic few birders are familiar with.
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.
For example, Danny Bystrak (Breeding Bird Survey) and Dave Ziolkowski (Bird Banding Lab) of the USGS indicated that changes would not have a substantial negative impact on their programs, and would be just a “minor annoyance.” Was there confusion that impacted data collection or research or birding? Did the process work?)
One of the two sub-species of Red Knot occurring in North America, the Rufa subspecies breeds in the Canadian Artic Region and migrates along the east or Atlantic coast of the United States. The other sub-species, Calidris canutus roselaari , migrates along the Pacific Coast and breeds in Alaska and the Wrangel Island in Russia.
Egyptian Vultures raised is isolation used rocks to crack eggs presented to them. According to these researchers, only the exceptionally intelligent herons acquire the skill of bait fishing. Just a bit of ingenuity can make a big difference for these herons and their progeny if they are breeding. The behavior was inherent.
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. Chestnut-collared Longspur is one of those.
Third, observing and photographing breeding birds and their young have become acts of ethical confusion as birders, photographers, and organizational representatives debate the impact of our human presence on the nesting process. Some people love books like that. Northern Flicker eggs in nest and nestlings.
Until recently, the population of tawny frogmouths in North American zoos was facing extinction — and breeding programs were largely unsuccessful. Through years of research, SeaWorld has made it possible for this chick to be raised by its parents.
The source of this ranking, BirdLife International, lists Bolivia as currently having 1,439 bird species, including 18 breeding endemics. Like most maps, colors are used to indicate seasonal status (breeding resident, Austral migrant/visitor, Boreal migrant, etc.). Distribution maps are also different from other field guides.
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 ).
Marc Hauser, a cognitive psychologist at Harvard University, recently opened his own such research lab and has 1,000 dogs lined up as subjects. In some cases, their research suggests that our pets are manipulating us rather than welling up with human-like feeling. Other facilities are operating in the U.S. and Europe.
Some of the lazier Common Moorhens apparently try to pass the arduous work of raising their chicks on to other species -a paper describes how Little Bitterns are utilized as surrogate parents. However, the authors call this a “new breeding tactic”, which seems to mix up the discovery of the tactic with the use of the tactic.
Birders often play a vital role in monitoring bird populations, contributing data to scientific research, and participating in citizen science initiatives that help track bird distributions, migration patterns, and breeding behaviors. They contribute to scientific research, conservation efforts, and the enjoyment of birding as a hobby.
So, while waiting for evolution to produce new birds for our life lists is inadvisable, we sometimes catch a break and every few years get a new species or two when some genetic research or study of breeding distribution presents enough evidence to split what was once considered a single species into a few new ones.
Conservationists at the Royal Society for the Protection of Birds (RSPB) have been using remote controlled drones to watch the nests of endangered breeds and monitor the progress of reintroduced species. Over time, it’s these physiological changes that can disrupt animals’ breeding or rearing habits.
A lovely looking and distinctive sounding bird (so they say, I sadly have not seen one…yet), the Kirtland’s Warbler can only be found during its breeding season in Jack Pine forests 5 to 20 years old in the northern Lower Peninsula of Michigan. Previously, even researchers had problems getting access to nesting Kirtland’s Warblers.
Bolivar Flats Shorebird Sanctuary was an amazing and unexpected treat, but that’s because I failed to do my research. I should have known that birding High Island meant I would be 20 minutes away from a place where hundreds of thousands of shorebirds and waterbirds rest, feed, breed, and generally have a good time. Clapper Rail.
This map shows the distribution of the World’s bird species, based on overlying the breeding and wintering ranges of all known species. And it raises a question: if all the birds are having a party over there, am I in the wrong spot? It makes me think what is the meaning of life, the universe and everything? Why am I here?
I guess most scientists would love to see their original research become the basis for a vast field of further studies. In terms of breeding behavior, starlings are a diversified group – some use helpers, others do not. ” If you happen to be a European Bee-eater , you are in luck. .” young in 1.5
For my new book, due out in 2012 from Houghton Mifflin Harcourt, I’ve been researching sandhill crane hunting. A Great Backyard Bird Count Miracle Best Bird of the Weekend (Last of January 2011) What is the International Bird Rescue Research Center Anyway? Or These Blasts From The Past What’s In A Name?
This week at 10,000 Birds, it’s all about how birds get around to bumping uglies (I’m talking about cloacas here), who they do it with, and how this actually leads to raising chicks…the birds and the bees of birds, you might say. Believe it or not, this is what “fidelity” looks like.
” Fortunately, most of these researchers could be taken off their antidepressants after proper sound recording was invented. , varied (or perhaps answered) by even, abrupt, squealing “fwuuuur”. Calls (of race erythrolaemum ) include low, musical purring “squar-squar-squar”.”
Way back when I started what turned out to be my thesis research (on humans), it became important for me to learn about bird migration. I was involved in the study of human movement and navigation on land, and there was a lot of research coming out about bird navigation. Another question this raises has to do with migration itself.
White-browed Tit Warblers breed in high-altitude scrub, with a preference for junipers. Unfortunately for them, this is what raising chicks requires. Balangshan is a mountainous area in Sichuan complete with a pass at an altitude of 4500 meters. And it is a great place for birding. This is the second part.
This is a delightful book, large (8-1/2 by 11 inches), filled with Sibley’s distinctive artwork and an organized potpourri of research-based stories about the science behind bird’s lives. His art is beloved (if you have owned a Sibley calendar at least once in your life, raise your hand) and his bird expertise is widely respected.
With regard to the Grey-backed Thrush , “further research should focus on identification of nest predators, implications of nest exposure and begging calls on nesting success, and breeding habitat requirements at different spatial and temporal scales of Grey-backed Thrush in fragmented landscapes of northeast China.”
A study on the breeding biology of Whitehead’s Broadbill was just published in May 2023 but leaves a bit of a puzzle as the breeding success is described as relatively high, meaning there should be other reasons for the population decline of the species. The Latin species name of the Penan Bulbul is ruficrissus.
Ka’ena Point is also a breeding ground for the Federally protected Laysan albatross, where 45 nests were being carefully monitored by the non-profit Pacific Rim Conservation. The oldest Laysan albatross was last seen raising a chick on Midway Atoll in 2016, at age 66. They are docile and devoted parents who will not leave their nests.
campus gardens – the Tropical Agricultural Research and Higher Education Centre, located 3 km east of the town of Turrialba. There was a Gartered Trogon right above me, and one cooperative Brown-throated Three-toed Sloth on a cecropia tree, raising its head to smile at us. A group (maybe 4-5 ex.)
