According to National Audubon Society , “Finch researchers are calling this year a ‘superflight,’ where every species of boreal finch is irrupting, or moving southward in search of food. In the breeding grounds for many migratory species, I look forward to warblers, flycatchers, and more. The birds connect us!
A company that bred Beagles for research will pay more than $35 million after pleading guilty last month to violating the federal Animal Welfare Act (AWA) by neglecting thousands of dogs at its Cumberland, Virginia, breeding facility. The payment includes the largest ever fine in an animal welfare case.
Before visiting the local animal shelter, I should have done some background research. Here are some things to consider when comparing different dog breeds: • Do you live in an apartment or a house with a small backyard? If so, make sure to get a breed that plays nice with both. Don’t let the dog eat your homework.
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. Tags: animal experimentation puerto rico animal research primates medical research.
That still leaves 11 Warblers that breed in Michoacán. Like the Common Yellowthroat , the Yellow Warbler breeds no further south than the central Mexican highlands. I must admit that I had the idea the Grace’s Warbler , common in our pine forests, were also at the southern edge of their breeding range here.
The Calliope Hummingbird is the smallest North American breeding bird 1. The males arrive on breeding grounds before the females and, according to their range map, they probably breed here in Shasta County. This is around the time of year I expect to start seeing the Calliope Hummingbird ( Selasphorus calliope ) at my feeders.
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. It is pointedly not an identification guide, though there is a lot of identification information in it, and it is not a coffee table book, though every page is illustrated.
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).
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.
That impressive number is a testament to the exponential advances in DNA-sequencing technology, but the researchers are quick to note it’s still less than 1% of the total genome.). Whereas previous genetic analyses of redpolls looked at just 11 regions of the genome (at most), Mason and Taylor examined 235,000 regions.
You don’t really know a bird until you’ve studied it on its breeding grounds. 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. Color markings on the legs and head are to identify individuals for research purposes).
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.
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?).

They've been planning to build a facility to breedresearch monkeys in Puerto Rico for some time. Tags: puerto rico animal research primates. Plus, the horrible pictures I've seen of strays in Puerto Rico. Plus the fact that I personally know the Latin attitude towards animals. Plus, well, you get this picture.
However, all too often, dog lovers choose a dog breed that they want without first considering how well that breed will fit in with their lifestyle. Yes, we fall in love with certain breeds: the short ones with long bodies, the adorable ones with wrinkles all over, or the hound dog with long, droopy ears. Activity Level.
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 Nor the funds to hire the researchers. Two years ago, I was counting active nests of Rooks in the flat agricultural landscape north of Belgrade, Serbia. nests per 1 km2.
So this new research is very interesting, and we applaud the scientists for their work. These researchers carried out two different major efforts that in combination advance our understanding of the evolution of the bird beak. Figuring that out would be a next step in this research, and will likely prove difficult.
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.
It’s a bird that rarely occurs inland, and outside the breeding season it spends its time far out to sea. In March, as the days start to lengthen, so the wandering birds return to their breeding cliffs. Adult pairs are very site faithful, and if their breeding is successful, they will return to the same colony year after year.
We found evidence that supported pairs as the fundamental unit of social structure, although these close associates were not always heterosexual breeding pairs and were sometimes trios. Perhaps one of the most interesting findings of this research is the detailed dynamics of inter-parrot interaction. This: Just like people.
Every spring, billions of migratory songbirds in Europe fly north to their breeding grounds. But researchers have now found evidence of a giant European bat that is plucking migrating birds out of the night sky. Several months ago, a group of bat researchers spent the night recording the sounds of a marshy Spanish forest.
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.
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.
states, 9 Canadian provinces, and 3 Canadian territories) are asked to be on the lookout for these birds as they migrate toward their northern breeding grounds. From March 1 through mid-June, birders in the Rusty’s range (38 U.S.
The non-breeding distribution is virtually unknown, although they are suspected to winter in northern South America (Howell and Web 1995). Until recently the vocalizations of Sinaloa Martin were unknown and known breeding sites are few and far between. Very little is known about this enigmatic species.
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.
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 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”.
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. Snowy Owl being harassed by an American Crow. Three owls have already had the devices attached and some pretty interesting data is being collected.
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.
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.
With populations plunging dramatically over the last decade, researchers from the Wildfowl and Wetlands Trust, Birds Russia, and a number of other conservation organizations made the always-controversial call to pluck eggs from the imperiled wild population and establish a captive breeding program as a final hedge against extinction.
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.
Of course Africa could not to be left out of the pink weekend so I have researched all African species whose official or alternative names include the word “pink”. Great White Pelicans showing the pink flush of breeding plumage. There are certainly some stunners involved. Pink-throated Twinspot. Photo by Adam Riley. Pink-breasted Lark.
This map shows the distribution of the World’s bird species, based on overlying the breeding and wintering ranges of all known species. It makes me think what is the meaning of life, the universe and everything? Why am I here? And where all those birds are? Map by BirdLife International.
Secondly, much of the appeal is that this is a bird we don’t see in the UK very often, for Waxwings are an irruptive species, and in most years only a few ever reach our shores from their breeding grounds in the boreal forests of Scandinavia. I’ve managed to see them, too, on their breeding grounds in Finland in summer.
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.
All New World Quail are highly gregarious, typically found in coveys or flocks except during breeding season. These could be the beginning of the formation of coveys, post breeding season flocks that form when the chicks become independent at about three months old. The birds scatter, sometimes in different directions.
New research in Current Biology suggests that concentrating efforts on saving the remaining four large populations of the Florida Scrub-Jay isn’t all that’s needed. Consequently, their breeding efforts with resident birds produce more and healthier offspring than “inbred” resident-resident pairings. ”
Birders flock to this haven, as it is a sanctuary for over 150,000 breeding Northern Gannets , making it the world’s largest colony. Northern Gannets on cliffs Dense Northern Gannet colony While researching this trip, there was a common theme in the articles relating to the gannets: Avian Flu hit this colony hard in 2022.
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. With all the research that has been done on lead vs non-lead bullets, there is no reason for ANYONE to use lead when hunting.
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.
It is not quite clear why they do this as it apparently does not affect breeding success. They have written a paper on the “Feasibility of counting breeding Pied Avocets and Black-winged Stilts using drones” It seems to work, actually – though about 20 percent of breeding pairs are being missed by drone surveys.
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.
