It reports on research that attempted to uncover whether flight originally started as a running leap, or a misdirected fall. The authors, whose paper appears in Biology Letters , emphasize that no baby birds were harmed during the research. Researchers plotted eBird sightings against satellite imagery of U.S. The verdict?
There was a time when I thought each bird species had its own individual song. Then I found out that there was this vocalization called a ‘call,’ so I thought each bird species had its own individual song (but just the males) and individual call. I do wish there was more about research on female bird song.
An impressive combination of research and artwork, combined with a pragmatic organization aimed towards quick identification, and education, Baby Bird Identification extends the frontiers of bird identification guides and is an important contribution to wildlife rehabilitation literature.
The socioecology of Monk Parakeets: Insights into parrot social complexity by Elizabeth Hobson, Michael Avery, and Timothy Wright, is a new paper in Auk , with this abstract: In many species, individuals benefit from social associations, but they must balance these benefits with the costs of competition for resources. but not steep (,0.1).
Here are some things I’ve learned from the Peterson Reference Guide to Owls of North America and the Caribbean by Scott Weidensaul: The Burrowing Owl is the only North American owl species where the male is larger than the female, albeit, only slightly larger. And the term is ‘non-reversed size dimorphism.’).
I routinely review recent eBird checklists for several of my local patches and recently noticed a few with weather information ( e.g. , temperature, wind, cloud cover, humidity, etc.) RainCrow then retrieves the weather information for the location during the time period of the checklist. from something called RainCrow.
Birders who submit their checklists to eBird likely know that their data may be used to conduct research on avian migration, range, or population. It has also been used by researchers from other fields, such as economists. They also obtained socioeconomic information about neighborhoods. Green spaces may also help reduce stress.
More than 50 years ago, the Hawaiian Goose (Nene) was one of the first birds listed under the Endangered Species Act, part of the inaugural “ Class of 1967 ”. Under the Endangered Species Act, any listing, uplisting, downlisting, or removal from a list requires a formal “rulemaking” process.
The feature distinguishes birds from other species; All birds have them, no other species do. Beaks vary across different kinds of birds, and this great diversity in beaks is part of the great diversity of the 10,000+ species of birds that exist today; Beaks thus facilitated the diversification of birds. So how did beaks evolve?
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).
There’s been some interesting bird research lately, having to do with the origin of birds ( new analysis of new and old fossils ) and the overarching taxonomy ( using DNA analysis ) but I’ve not had a chance to absorb this weighty new knowledge so I’ll probably write about it next month.
Even the Latin species name soror (“sister”) indicates the similarity to another pitta species (blue-naped). The eBird description of the Small Niltava starts with the surprisingly dull statement that “size distinguishes this species from other niltavas” Who would have thought.
Listed as Near Threatened, this charismatic species has a tiny distribution restricted to central Costa Rica, especially in the Central Valley. Over a few years, I have already seen several places where I watched this species, even showed this species to visiting birders, bulldozed and prepared for housing.
I’ve been fortunate to see two Penguin species in the wild (African and Galapagos) and have dreamed of seeing more–maybe even all!–especially The goal of Around the World For Penguins is simple: Describe the 18 species of penguin and their breeding grounds “from the perspective of a traveller.”
A QR code contains information, and once scanned with a QR code reader, an app you can upload to your smartphone for free, you will be able to read or, in this case, hear the information. A little research revealed that these are old names of birds that have been split into different species.
It’s also about personal journeys, where knowledge comes from and how it is shared, investigating the past through the lens of history and the lens of informed imagination, learning how to negotiate the grays of our ornithological heritage, and the magic of discovery. The mind reels.
One researcher tested British school children to see if they could find their way home by driving them blindfolded, in a bus, out into the country and asking them to point their way home. The same researcher then did the same thing but with big magnets strapped to the children’s heads. If so, is anyone looking for this?
I’ve been banding birds of prey for 5 years it is easy to put ourselves through endless fog days and cramped quarters when the end result is good research, accurate data, and minimal impact on the raptors we encounter. We have had quite a run of birds overhead as they stream down along the Pacific flyway.
Here are ten titles (it could have been more) selected for their uniqueness, excellence in writing and research, and giftability. There is a wealth of information about these marvelous creatures, given via prose essays, and charts, and tables – it’s all quite user-friendly. But this is more than a coffee table book.
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.
The plight of these birds inspired her, along with a handful of other concerned individuals, to do everything they could to save them, and by April of 1971 International Bird Rescue Research Center (now known as International Bird Rescue) was incorporated as a non-profit organization.
There is also a research institute dedicated to wilderness: the Aldo Leopold Wilderness Research Institute is an interagency facility located at the University of Montana. It is the only federal research group dedicated to studies needed to manage the National Wilderness Preservation System.
She does, and her narrative serves as a role model for how to write about birds simply and knowledgeably; informing birds’ family stories with scientific facts and research findings. Some chapters focus on one species (Yellow Warbler), some on several related species (Chickadees and Nuthatches).
But does the value of a particular trip come from the number of birds seen, viewing a particular species, seeing an endangered species, catching a glimpse of a rarity, adding a lifer, or something else? I emailed the authors and asked about their research and their use of eBird data. Birders derive “value” from birding.
No matter where you are in the country you can put in the address of the wildlife emergency, narrow your search to the species and problem, and contact numbers will pop up. AHNow’s database includes wildlife rehabilitators, rescues and hotlines, as well as veterinarians who treat wildlife.
That’s pretty amazing–Bolivia has more bird species than India! The source of this ranking, BirdLife International, lists Bolivia as currently having 1,439 bird species, including 18 breeding endemics. The guide covers 1,433 species, the number of birds documented at the end of 2014, the cutoff point for the book.
With some research, I ended up with more questions than answers, making these birds all the more interesting! In Florida, the species shows up annually (and in multiples!) From these notes, there seems to have been a long term presence of this species in the sunshine state. where are these birds coming from?
Because, let’s face it, when you get off that plane and look at those severe volcanic landscapes and then find yourself face to face with one of the islands’ four mockingbird species, you’re not going to think, “Oh, look, lava and a mockingbird.” The 11th chapter is on research and conservation challenges.
The results of this research paper appear in the Journal of Zoology. It is probably the case that the rapid spread of Lyme Disease from Connecticut to the rest of the United States and adjoining regions of Canada was because some species of birds (but not all) can carry Lyme disease, and can also carry the ticks that carry the disease.
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.
Leventis is a businessman from London involved in wildlife conservation in Africa, including the establishment of an avian research institute in Nigeria and an amateur photographer. Species accounts for all 2,792 bird species. The next one is as exciting as the country accounts – the species accounts.
However, there are those species which have a hard time bringing attention to themselves such as Yellow-shouldered Blackbird , Giant Nuthatch , and Vinaceous-breasted Parrot. Regardless of their popularity, these species and the threatened ecosystems they inhabit are equally spectacular. Photo by Dušan Brinkhuizen (www.sapayoa.com).
And apart from local people, primate researchers sometimes spot it, but it is a species seen by fewer than ten living birders. The rest of the 216 pages long book is devoted to various African bird families and half a dozen individual species. He has authored several other books and many articles, largely on natural history.
A number of research projects have sought to determine if some of these human brain abilities are found in other animals. Even among our primate relatives, whoa are generally very smart, “Theory of Mind” is found in only a few species. But that’s another story. Here’s the idea. The graph shows the results.
This is “the deep cradle of Western ornithology: the birthplace of bird study,” he tells us as he writes about gazing at the 8,000-year old depictions of “flamingos, herons, raptors, avocets and many other species” (p. Common Guillemot research at Skomer Island, Wales. Beagle , pt.
Given that according to the HBW, the species prefers dense primary and secondary montane forests, the note that the bird also forages among kitchen waste (in the same HBW entry) seems somewhat incongruous. Fish & Wildlife Service has a web page for this species – but it contains absolutely no information.
The second edition of the National Geographic Complete Birds of North America, 2nd Edition has one of the longest book names in bird bookdom: National Geographic Complete Birds of North America, 2nd Edition: Now Covering More Than 1,000 Species With the Most-Detailed Information Found in a Single Volume. This volume is no exception.
The section South Georgia Wildlife describes 65 species of birds, 20 species of sea mammals, nearly 60 species of insects, and more than 40 species of flowering and nonflowering plants. Thirty-six Tubenose species are covered to varying degrees, depending on their status.
The story of the White-winged Guan , in some ways resembles the re-discovery of some species thought to be extinct. Some of these specimens had labels with basic information and were stored for further work at a later time. The decades of storage in a museum came after it was regarded as an extinct species. What a horror!
So armed with some knowledge from the “ Access Considerations for Birding Locations ” page on the Birdability website and some research, I twice visited the Tualatin River National Wildlife Refuge near Portland, Oregon with accessibility in mind. Thus, there is a good amount of online information for planning purposes.
It was on the island of Trinidad, at the Aripo Agricultural Research Station, where all of these photographs were taken. They are considered a Species of Least Concern by BirdLife International because of their large range and stable population. young male Red-breasted Blackbird Sturnella militaris. female Red-breasted Blackbird.
The official Ontario bird checklist, produced by Ontario Field Ornithologists , June 2022 listed 506 bird species**, putting it in the top tier of U.S. Small Species Accounts: Each species is allotted one page (with certain exceptions) offering basics–bird names and size, one or two photographs, and a one-paragraph description.
” The interlocking wheels of crabs, migration, birds, tides, marsh, beach, fishermen and researchers are described in an unhurried pace in ten chapters. The chapter “Horseshoe Crabs” illustrates why this is THE keystone species of the Delaware Bay. The visual beauty and textual facts are a strong combination.
