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?
Big news about a small bird broke earlier this month when bird researchers from several nations announced that the species formerly known as Spotted Wren-Babbler ( Spelaeornis formosus ) — a tiny, secretive bird of montane forests from the eastern Himalayas to southeast China — is not a Spelaeornis wren-babbler at all.
Fish and Wildlife Service has listed the “Rufa” population of Red Knot ( Calidris canutus rufa ) as a threatened species under the Endangered Species Act (ESA). The other sub-species, Calidris canutus roselaari , migrates along the Pacific Coast and breeds in Alaska and the Wrangel Island in Russia.
A prime example is a report newly released by the Center for Biological Diversity which suggests that, by and large, in the United States, the Endangered Species Act is indeed helping to save the birds it protects. Continental U.S. So, how about we add most of the rest of North America’s birds to the list?
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.’).
These hurricanes prompted a personal interest in the impact of hurricanes on birds, so I did some research, which ultimately led to an article in the April 2018 issue of Birding magazine. For example, hummingbirds must find patches where there are still flowers. Some species experienced dramatic declines.
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.
Or would be, had I encountered more of them – so far, I have seen only a very small share of the approximately 233 woodpecker species, and got decent photos of an even smaller number – not much more than 10% of all of them. So, writing a post about them is easy.
For example, humans have “Theory of Mind” which is not a theory in the scientific sense, but rather, a capacity whereby we have an internal theory of what is going on in other people’s minds. A number of research projects have sought to determine if some of these human brain abilities are found in other animals. Here’s the idea.
For example, the survey (of eBirders) found: “Nearly all respondents (99%) indicated they participate in birdwatching or birding.”. For example, (all quoted passages are lightly edited for readability): A large majority of respondents indicated their birding activities include 6 of the 7 activities asked about in the survey. “A
Here are ten titles (it could have been more) selected for their uniqueness, excellence in writing and research, and giftability. For example, many photos are shot in poor light, obscuring the true colours. The guide covers 265 of Maine’s 461 bird species: common nesting species, common migrants, and wintering birds.
For example, hunting is not permitted in most NPS wilderness areas, but it is often allowed in wilderness areas managed by the other agencies. 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.
Even better, just a few meters away from the food vendors, it is not too crowded, and the palm trees attract a number of birds, including two species of parrots. That is mainly the Philippines, as indicated by the species name lucionensis (Luzon is the Philippines’ biggest island). The first one is the Blue-naped Parrot.
The species was named after John P. I suspect there is little opposition to changing the names of species with particularly sordid namesakes. For example, the standard QWERTY keyboard is arguably inefficient and there are likely better alternatives. After much ado , the name was ultimately changed to Thick-billed Longspur.
I have always assumed that scientific researchers can overlay weather information on checklists for their research, but absent manual entry, that such information would not be available to me. An example of the same RainCrow result in an eBird checklis t is below. Q: Should we expect any additional eBird projects from you?
For example, the panel (see below) included three members of the pro-change Bird Names for Birds group (more representation than the Cornell Lab of Ornithology , the National Audubon Society , and the U.S. For example, Meriwether Lewis of Lewis and Clark Expedition fame, has been honored with the names of multiple U.S.
On a recent filming trip with Tropical Birding in Ecuador I had the awesome experience of getting up close and personal with two bizarre manakin species. Take the Club-winged Manakin for example. The best explanation comes from observations of slowed-down high speed video by researcher Kimberly Bostwick. v=hEUr01attXs a.
A logical and outstanding successor to The Genius of Birds (2016), Ackerman’s award-winning book about bird cognition, The Bird Way explores the diversity of bird behavior, the norm and the extremes, with an emphasis on cutting-edge research and findings that explode assumptions. Yet, the research projects are never the whole story.
As one topic example, Marconi Campos-Cerqueira presented a paper entitled “Past, Current and Future Distributions of Puerto Rican Fauna: Implications from Climate Change.” He modeled likely future suitable habitats in a climate change scenario for a number of bird species of conservation concern. by Eliza M.
If you have birded very long, you are probably aware that members of closely related bird species, when their ranges overlap, sometimes love each other very much, and have babies. When this happens particularly often, such hybridization processes can result in entirely new species.
This is an idea that has been around for more than a century, to which recent research has given considerable support. For example,this may be a case of non-linear evolution. The fossil record has a number of examples of two-steps. Birds may have evolved from an ancestor with four wings. Only kidding.
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.
A little research revealed that these are old names of birds that have been split into different species. Water Pipit is now known as a European species; the American subspecies became the full species American Pipit in 1989. Scientific names don’t reflect the massive changes to species in the warbler family.
Just last year, 5 new bird species and 5 new subspecies were discovered in a few short weeks of fieldwork on the islands of Taliabu, Peleng and Batudaka. In recent years Indonesia has been competing with the Andes as the region giving rise to the biggest number of undescribed bird species (naturally, all of them endemics).
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 proximity to the Myanmar border is reflected in the presence of Burmese Shrikes here – on the wrong side of the border, but it is well known that this species has never been particularly good at geography. This photo explains the scientific species name haemacephalus (bloodheaded).
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? For example, binoculars and field guides have a cost that can be measured in dollars. What is that and why does it matter?
Nearly 70 species of parrots have been recorded flying free at some stage or another in Miami, including Hyacinth Macaws. Dozens of other introduced bird species, largely escapees from pet owners, now call Miami home. But I couldn’t help but get more excited about the countable species as opposed to the uncountable ones.
” 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 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.
The USVI are smaller and have fewer habitats and, as a result, fewer bird species. Much of the research regarding Caribbean ecology and ornithology has been conducted in Puerto Rico. Puerto Rico has a checklist of 269 species, 207 of which are migratory and the USVI has a checklist of 149 species, 124 of which are migratory.
If you know or hear of other examples, please let me know and I will add them to this list. While studying, he also worked on various conservation/research projects (parrots, wagtails, vultures, and anything else that flew) and ringed thousands of birds. yourbirdoasis, I added a list of some examples which I had found.
Where predators are rare, turning more attention to feeding might produce a Darwinian benefit, for example. Most likely, all individuals of a given species have very similar genes guiding very similar developmental processes, but produce different results because the plasticity itself is selected for. Invasion of the birdie snatchers.
Jonathan Elphick and John Fanshawe provided “specialist research” and support.” Additional back of the book material includes a Glossary, Biographical Details, a Select Bibliography, Notes, Credits, an Index to Species and a General Index. Larks, for example. Eagles are national symbols of the U.S.,
These researchers preferred this property for their research due to its close proximity to the Arenal Volcano and resplendent natural environment. When the researchers returned home during their time off, they would tell their friends and family about the magic of this place, and year after year more and more people began arriving.
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.
Some time ago, I was doing research of waterbird migrations with a friend of mine, a young ornithologist currently busy writing his Ph.D. thesis and trying to annoy most of us by uplisting some subspecies to full species and downlisting some species into mere races! Trust me – he was capable of forgetting his head.
When I read somewhere that Pygmy Geese were not actually geese at all I started doing some research. For example, the African Spur-winged Geese and the Blue-winged Geese suggest a close lineage to ducks but with some strange attributes. And of the the three species, the African species is without debate the most gorgeous.
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”. Another southern African endemic, this species ranges widely across the dry grasslands of central South Africa, Namibia and Botswana. Pink-throated Twinspot.
The Peterson Reference Guide to Seawatching offers two types of information: Species Accounts–descriptions of 112 birds within 15 families as they appear over and on the water, and Where to Watch, brief descriptions of 47 sites on the North American eastern coast and interior recommended for seawatching. No rails or gallinules.
I want to talk about this research but if you really want to know more about it, don’t rely on me; one of the co-authors of this important paper is Darren Naish, who happens to be a stupendous blogger, and he has written the research up here. So, for example, humans are apes. Meanwhile I have a few random thoughts.
