Howell does not place the White-tailed Hawk anywhere near Morelia, but I have seen it in every cuadrant of the city, and know for a fact that it breeds near the church I pastor. Mexico need much more citizen science, and there are far too few people doing it here. They were probably not preparing to go south.
We drove for about 290 km through the 400 square kilometres expanse of Pancevacki Rit and found 8 breeding colonies with 252 occupied nests, or a density of 1.6 Two years ago, I was counting active nests of Rooks in the flat agricultural landscape north of Belgrade, Serbia. nests per 1 km2. And what is the trend of those Belgrade rookeries?
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 adventure of the second European Breeding Bird Atlas, or EBBA2, was the topic of one of my first posts here at 10,000 Birds: In a warm Catalonian March, Barcelona is filled with sunlight and full of Rose-ringed and Monk Parakeets. In a very short time, we get two responses, two birds calling from opposite directions.
Another challenge to bird research is that it is woefully underfunded and relies heavily on citizen science. If you have an advanced degree in biology with an emphasis on birds , it doesn’t guarantee that you will always work with birds. You may work in biology, but it could be in any field.
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.
Not only has this live camera feed provided a wonderful educational resource for science teachers across the country, but it has also shed light on some very interesting behaviors of these owls. The colony has grown supporting up to 3 pairs of owls, all breeding at once! One of the owls with a frog after a rainstorm.
Flight Paths traces the history of migratory research in nine chapters, starting with the earliest attempts to track birds, bird banding/ringing (which she traces back to Audubon), and ending with ‘community science’ projects such as Breeding Bird Surveys and eBird. THIS IMAGE NOT IN THE BOOK. Schulman, 2023.
You could raise both, given that there are 40 million Pheasants released in the UK each year and previous research by the industry’s own science lobby (Game and Wildlife Conservation Trust) had found little evidence of raptor take (0.6% of nearly 500 radio-tagged releases).
Beginning this year, New York State embarked on its third-ever breeding bird atlas , and it’s the first one I’ve been able to participate in as a birder. Over the last several weeks there, I’ve watched them gather bits of straw and other sundry materials and ferry these back to their nest holes in the old barn walls and eaves.
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.
The proposed primate breeding facility would violate both the letter and the spirit of Puerto Rico’s progressive new law, which strictly limits the use of animals in experimentation.
Also from BirdLife International: In general it prefers areas where vegetation, boulders or other landscape features at ground level provide tunnels in which to shelter and to breed. The bird will therefore now be known as. Atlantisia Rogersi.
Though it was well-known to the Native American populations that shared its space, the black-footed ferret was overlooked by Lewis and Clark and all subsequent Euro-American expeditions, remaining officially unknown to science until John James Audubon, his sons, and the Rev. But the ferrets kept dying.
Do it for science! And, oddly, it seems that no one knows too much about what these visitors from the north are up to while they are down here. 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!
They breed in colonies scattered around the Antarctic continent (the number ranges from 60 to 70, and as Kooyman points out, the colonies can drastically change in size from year to year) on the ice (and one of the things I learned from this book is how many different kinds of ice there is in the Antarctic) in the darkest months of winter.
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).
The species is a cooperative breeder – chicks from previous breeding attempts help bringing up the next batch of chicks, like baby-sitting teenagers, though the latter are not related to the kids they babysit and also mainly do it for money, so I guess these two things are not really comparable at all. ” Hurray for science.
If the birds had been breeding, the scientists say that they would have found genetic “intermediates&# – birds with genes from both species. Hey, science people (scientists?), “But we didn’t find this, so we think [the two species] have formed some kind of reproductive barrier to each other,&# Prof Saetre said.
There is a depressing finality about extinction, but knowing when for certain something is extinct is an imprecise science and on occasion we’ve gotten it spectacularly wrong. Where does it breed? Efforts are underway to try and find where they breed. Was it distinct from the extremely common Wilson’s Storm-petrel?
This is a book that people come to for the plot and the science. All actual captive breeding efforts failed for a reason, after all. I’m ok with fantasy, but not with pseudo-science. But what of that? This, I am sorry to say, broke the book for me.
Males of this species are more brightly colored in their non-breeding winter plumage. In 1996, several pipit specimens were collected for DNA analysis and it turned out that there was not one, but two new species to science in this sample! A dancing Blue Crane , South Africa’s national bird.
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.
Only in the late 1980’s was it “rediscovered” so to say, with the male being found at Imuya Cocha and described to science for the first time. For example nothing is known of its breeding habits, any accounts of its diet (it is assumed to feed on insects and other arthropods), ways of foraging and movement (presumed resident) are wanting.
It’s a book that counterpoints and combines facts and personal experiences, science-based and eloquent writing styles, textual description and visual information, a history of abundance and an uncertain future. The Profiles are engaging reading, much livelier than most identification guides, reflecting the broader scope and goals.
Currently, the population is near saturation point in this small preserve at about 226 mature individuals — it is simply too small to host more breeding territories. Brood parasitism from Shiny Cowbird is also a major issue (42% parasitism rate if unmanaged). Pale-headed Brush-Finch are usually feeding on or near the ground.
It is easy to tell when some species become extinct — a Martha or a Lonesome George dies and there are no more, not now, not ever (until science fiction kicks in.) No, this is a bird that, in the male breeding plumage, shows off a robust pinkness of head that is all the more vivid in contrast with the bird’s dark body.
They breed in the tunnel area, giving those birdwatchers anxiously waiting for the Chinese Monal to show up something to do in the meantime – like watching the shift change. Sounds a bit like some weird Nazi eugenics experiment to me, but I guess it is just science.
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. Both species can theoretically breed in central Mexico, but in my experience are almost exclusively winter visitors. But obsessed I am. And it brought friends.
If you have always wondered what the minimum anesthetic concentration for isoflurane and sevoflurane for the Crested Serpent-eagle is, science has an answer. The breeding ecology of the Yellow-bellied Warbler was actually studied exactly here at Nonggang in 2019 by 3 Chinese researchers. So you just have to look at the photos for once.
No wait, they were, but they had experienced so much genetic drift and selective pressure that they now constituted a unique breed in their own right. Also, they were infested by a species of ear mite unknown to science. And so, a breed association formed to preserve these goats. (No
Identification of abnormal birds such as this one is not an exact science, but this one seems to break down as one half White-throated Sparrow and one half Dark-eyed Junco. Structurally, that long and low body, the pot-belly and the flat head. That slate-gray breast turning to white belly, the faint hint of a white-throat.
More than 150 bird species are known to have become extinct over the past 500 years, and many more are estimated to have been driven to extinction before they became known to science. There has been growth in the breeding population at the colonies in Morocco (now estimated at 106 breeding pairs and approximately 500 birds in total).
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.
With climate change appearing to expand the skeeters’ range, according to recent research in Science Advances , the birds have fewer safe places to hide. In particular, the honeycreepers of Kaua’i are at risk of being wiped out , due to disease-spreading mosquitoes. Fish & Wildlife Service).
Every spring, billions of migratory songbirds in Europe fly north to their breeding grounds. Museum of Natural Sciences and N.C. But did you know that there is a bat that specializes in eating birds that are migrating at night? Giant Bats Snatch Birds from Night Sky. A group of researchers at the N.C.
Penguins are flightless, but some species locomote over long distances on antarctic ice to travel between breeding grounds and the sea. Fossil Evidence for Evolution of the Shape and Color of Penguin Feathers Science, 330 (6006), 954-957 DOI: 10.1126/science.1193604 Salas-Gismondi, R., Altamirano, A., Shawkey, M., Vinther, J.,
He writes about how experienced birders think, and how they draw on the sciences of weather, geography, and ecology to analyze where the birds will be. Lovitch takes the practice of birding ten steps beyond. I would like to add Badbirdz Reloaded , a companion site on Florida migration, run by Angel and Mariel Abreu.
There is a very distinctive smell found on seabird colonies, where thousands upon thousands of birds come to breed and, coincidentally, deposit large quantities of waste. As well as gulls the islands home large colonies of Brandt’s Cormorants. This is done at night, over three nights, and is quite the operation.
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.
The authors’ detailed delineation of problems with the accuracy of NYC breeding bird surveys or with the limits of historical writings may test a reader’s patience. Because, as this book demonstrates so well, it is sometimes important to look back in order to move forward. This is a project that clearly spanned decades.
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.
Not only are most domesticated duck breeds descended from A. oustaleti ) is ever granted posthumous species status, it will represent one of the most short-lived vertebrate species known to science, with a lifespan measured only in tens of thousands of years from the first rendezvous between Mallard and Pacific Black Duck ( A.
Quite likely, these birds are also the inspiration for Australian science communicator Dr. Karl Kruszelnicki. ” Like many Australian birds, they breed cooperatively with a varying number of helpers, often siblings or older offspring. Thanks to Clare for introducing me to him. Within group, all males copulate with all females.”
