A breeding bird atlas is a special kind of book. For birders, it’s the extremely large book, shelved in a place where it can’t crush the field guides, used to research the history of a bird in their area. So, what exactly does a breeding bird atlas contain? The resulting book, 616 pages in length, 6.4
The Guan had never been seen in the wild after Polish Naturalist Wladyslaw Taczanowski collected one individual in 1876. Nineteenth and early twentieth century naturalists collected birds on long and arduous exploratory expeditions in the New World. A large and striking bird like this would be hard to neglect in a museum collection.
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. Researchers have a good understanding of Rusties’ summer and winter locations, but don’t know much about where they stop along the way, in what numbers, and for how long.
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. I present here an annotated collection of photos documenting the entry of new parrotlets into this world.
Three owls have already had the devices attached and some pretty interesting data is being collected. 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.
En route they will be “birding in nearly every country in mainland North and South America,” and, as they say on their excellent blog , “Our journey is about collecting valuable data on bird species, their status and distribution, current conservation issues, and more along the way.
Heermann’s Gulls form large breeding colonies on arid islands in the Gulf of California, Mexico, from March through July. The largest colony exists on Isla Raza, where an estimated 90–95% of the total world population breeds 1. This photo by Basar from Wikipedia Commons shows the adult in breeding plumage.
We’re always interested in what he’s up to and pleased that his research and our collective interest in cool birds can come together in such an opportune manner. Please read and then vote for either Nick or Maria’s research! Would you support research on birds with just a click on Facebook? My Project.
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.
Smith is the Staff Scientist Emeritus with the Smithsonian’s Tropical Research Centre in Panama. The work was widely cited, followed up with an article in Scientific American and the research appeared (and I may be wrong still appears) in textbooks. It is worthy of a much longer look than this one here.
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.
It was on the island of Trinidad, at the Aripo Agricultural Research Station, where all of these photographs were taken. Trinidad is the northern limit of the range of the Red-breasted Blackbird , though it is unclear if the occasional birds that show up in Tobago are wanderers from Trinidad or northern South America or are breeding there.
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.
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”.
Aplomado Falcon ( Falco femoralis ) by Jon David Nelson Shakeups for shearwaters and murrelets Xantus’s Murrelet ( Synthliboramphus hypoleucus ) has been split into California-breeding Scripps’s Murrelet ( Synthliboramphus scrippsi ) and Baja-breeding Guadalupe Murrelet ( Synthliboramphus hypoleucus ).
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 species is recorded in the form of a published photograph or a specimen archived in an ornithological collection.
Further research revealed the Bird Hybrids blog ( [link] ) has several revealing photographs of this (and many other) hybrids. I’ve seen some weird-looking hybrids in duck collections. Many years ago a friend of mine kept a small but varied collection of ducks and geese.
Although Henslow’s had been reliably found in nearby Sharon Springs for many years, the last documented sighting was in 2008, and the sighting startled longtime birders, waking them up to the fact that breeding sites in the state were rapidly being lost. I like the journalistic flavor added by these interviews.
You can probably understand the disappointment of a herpetologist friend of mine when he discovered that his very research transect was now paved. There’s enough scientific data collected already ( eBird illustrated checklist ), it is not as if we really need more. I’d rather not discuss my disappointment.
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?
Author Joshua Hammer, who previously wrote about a different type of real-life-unexpected-caper in The Bad-Ass Librarians of Timbuktu , read about Lendrum in the Times of London in 2017, realized the possibilities, did the research. And, how they betrayed that trust, stealing eggs for years and, possibly even worse, falsifying research data.
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.
Asking myself that question quarter of a century ago, I snooped through a collection of research papers in the Natural History Museum in Belgrade (before the Internet, I really had to go through papers) and found the “Ornithological Notes from the Pancevo Wetlands 1909-1917” by dr Jeno Nagy.
But new research, published in The Auk , suggests that this narrative may not provide the whole story. The data, collected from more than 500 owls over 18 years, appears to contradict the theory that southern-wandering Snowies are struggling to stay alive.
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.
The guide covers the all–1194 species in the Species Accounts, including 959 native breeding species, 219 Nearctic migrants, 8 breeding visiting species, and 5 introduced species. Of the native breeding species, 112 are endemic or “very nearly endemic.” (Can Can you guess which of the species cited above are endemic?
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. There are more than 1,300 distribution maps, indicating resident birds, breeding visitors, and migrants. So, this is no ordinary bird guide.
Seney National Wildlife Refuge was established in 1935 as a refuge and breeding ground for migratory birds and other wildlife.” Swan Lake Refuge is managed as “a refuge and breeding ground for migratory birds and other wildlife”. Seney National Wildlife Refuge : Expand migratory bird hunting, upland game hunting, and big game hunting.
I had made the trip to this area to continue my research data and photo collection on the Acorn Woodpeckers , but the balance of my day turned out to be pretty amazing. The first was five beautiful Lazuli Buntings , all in their bright breeding plumage. It paused just long enough for one quick photo.
This is the story of Fox’s experiences on board the Achiever, the research vessel of the Raincoast Conservation Foundation. The Achiever’s survey voyages took place from 2005 to 2008; the goal was to collect baseline data on sea mammals and marine birds. Northern Fulmar, image courtesy of Peter Hodum.
Approaching failed tests as a celebration breeds a company culture of learning and experimentation, as ideas are no longer thought of as good or bad but tests that must be set up. A testing budget is essential, and organizations should communicate internally that this budget is an investment in marketing research and development.

One proposed explanation by the researchers for this phenomenon is that similar-looking birds reduce their risk of predation, as predators find it more difficult to focus on and isolate a single target. Interested in doing research on the Orange-bellied Leafbird ? malayana had been collected. hardwickii and C.
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.
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. It’s a very mixed chapter.
Other research (cited on the rather straightforwardly named website www.genderinclusivebiology.com) found that 80% of gay swan couples successfully fledge their young, compared with only 30% for straight couples. As I only saw one loon at Fengxian (a Red-throated Loon ), I do not have to choose a collective noun anyway.
A little bit of research when I got home unraveled the ways of publishers here and in Great Britain. Do not buy these books, unless you are collecting old bird books. The accounts aim for specificity and authority; dates and locations of rarity sightings are given, and research articles on nesting and behavior are cited.
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. You can see why here.
’ Gorman has read and distilled probably every research study ever written about Wrynecks or related to them; my quick count of the citations in the 16-page References section came to 295. and the rural Austrian folk name natterzunge or ‘adder tongue.’ Practically every sentence is documented with these studies.
Here are some of the questions that were running through my mind as I read Owls of the Eastern Ice: A Quest to Find and Save the World’s Largest Owl : (a) Is ornithological research always this dangerous? (b) He wanted to do research that would have a conservation impact. Slaght provides funding from research grants.
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
And in my customary environmentally friendly approach to recycling bird photos, I have collected some of them in this post. The falcon breeds in south-eastern Siberia and Northern China but winters in Southern and East Africa. Still, coming here often guarantees to see some of them eventually. Still as impressed as before?
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). photos per 100 trap nights.
