Doug Futuyma believes in science and in the scientific basis of evolution. How Birds Evolve: What Science Reveals about Their Origin, Lives, and Diversity by Douglas J. Here are good, complex questions about why this diversity exists, how it came about, and what is its function when it comes to species and overall avian survival.
The magnificent history and diversity of birds on Earth came into sharper focus this month with the publication of 28 new scientific papers in Science and other journals. processed the entire genomes of 48 bird species and compared nearly 42 million base pairs of DNA (Hackett et al. American Flamingo photo by Dick Culbert).
Proving that cruelty knows no bounds, some (language unsuitable for a family blog) in Virginia Beach is shooting blow darts at birds. Meanwhile, an Oregon farmer caught a beating from a neighbor irritated by his loud “bird cannons.” (Who Who knew there was such a thing?).
Marybeth learns as she birds, embraces listing goals as a means of engaging with community, unabashedly enjoys a little competition, struggles to balance her absolute joy in birding with unexpected, life-and-death family obligations. Adventures of a Louisiana Birder: One Year, Two Wings, Three Hundred Species. ” I wondered.
This research suggests that the boom isn’t due to an influx of newcomers, but rather because more local birds are flourishing and successfully rearing families. If there is one silver lining to all of this gloomy news, it’s that the efforts of birders truly make a difference in helping to advance science.
Lees and Gilroy delineate vagrancy status and trends for every bird family worldwide, highlighting examples, synthesizing research, and framing it all with their own thoughts and conclusions. The guide covers 265 of Maine’s 461 bird species: common nesting species, common migrants, and wintering birds.
I was looking for a new project to write about on Wikipedia, something unusual, and this species appealed for reasons I can’t quite define. It was both mysterious and plain. . Juvenile White-naped Xenopsaris by Hector Bottai (Creative Commons). And here’s what I found for Argentina… And for Santa Fe.
Originally considered monotypic, two species are now recognized. Drakensberg (or Orange-breasted) Rockjumper is a Drakensberg Mountain species whose range is shared with the tiny landlocked kingdom of Lesotho. Males of this species are more brightly colored in their non-breeding winter plumage. the Rockjumpers.
Blackbirds, as a family, often have those simple descriptive names that are easy to mock ( Yellow-rumped Warbler , ugh) until a non-birder comes describing such a species to you and asking for an ID. He described the Brewer’s Blackbird for science more than a decade before Audubon.
Nonetheless, I thought it might be interesting and informative to review a DVD put out by Crowe’s Nest Media , a family owned and operated company, which is how I found a copy of Your Backyard: A young beginner’s guide to identifying 18 common feeder birds by sight & sound in my mailbox earlier this week.
And now we enter into a family of birds more or less unknown to non-birders. And truth told, over the years they’ve been something of a square peg for ornithologists too, not fitting precisely into any of the known families of birds. I would never have believed it, but if the science says so who am I to argue otherwise?
The Florida sub-species of Burrowing Owl is now classified as a threatened species in Florida and it is one of the rarest sub-species of Burrowing Owls. Loss of habitat due to development, disturbance at burrows and negative interactions with humans are some of the threats facing this charismatic species.
For one thing, we become more aware of cultural biases in our science (new findings on warbling female birds, for example, reveal both gender and geographic biases). Many popular science books have neither. As Ackerman explains in her Introduction, studying extreme behavior brings new insight into what we think we know.
At this moment, Baihualing is the eBird hotspot in China which has by far the largest number of species – 486. With 398 species, Nanhui is trailing far behind despite being covered by a much larger number of checklists (2225 compared to 608). But that is science in hierarchical institutions).
Unlike many endemic species they aren’t remotely rare, and can be seen just about anywhere in the country, and they are also amazingly confiding, allowing close approaches and even coming close to us of their own volition. The family also reaches into India and as far east as samoa and Fiji. Also known by its Maori name of P?wakawaka,
Guiding aside, Howell is a research associate at the California Academy of Sciences and the author of many books, including Petrels, Albatrosses, and Storm-Petrels of North America (Princeton). We have tended to a liberal (= realistic) direction when recognising species.” And that is what recommends Steve N. And now – the photos.
There’s a little hint of white in the malar and throat too, which would seem to be a problem for the species Black- chinned Sparrow. 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.
For example, on finding gulls: Close study of gulls is not for everyone, and birders shouldn’t feel obligated to get deep into it if you prefer colorful, less-confusing, families of birds. Most of these photos are by photographers associated with the USFWS and Wisconsin Dept. of Natural Resources and by Nate.
This has happened before, Archaeopteryx and the bird family tree have had an often tenuous relationship. But it is utterly bewildering to me to see news reports about this recent science that read “… An icon knocked from its perch&# or “Archaeopteryx no longer first bird.&# What evolved into what?
The Trogon family (and order, since the order only includes one family) is quite widespread, being found in all the tropical (and some subtropical) regions of the world. Honesty requires that I confess to having seen none of these species. These species are visually very similar, with subtle differences in their tail patterns.
Or, one of the 145 species of Glass frogs living in the Cental and South American rainforests, I could look through the transparent skin on their undersides and see their internal organs. All species of frogs and toads share the fact that they are amphibian creatures, they have two types of skin gland, four legs, and, well, they jump.
There is a fantastic paper just out in Science : “Sustained miniaturization and anatomoical innovation in the dinosaurian anceestors of birds” by Michael Lee, Andrea Cau, Darren Naishe and Gareth Dyke. The paper that just came out in science has the following spectacular conclusion. Science , 345 (6196 ), 562–566.
Artists rendition of Inkayacu paracasensis There are 17 living species of penguins, which make up their own Linnean family (Spheniscidae), which is the only family in the order Sphenisciformes. Penguins are flightless, but some species locomote over long distances on antarctic ice to travel between breeding grounds and the sea.
Quite likely, these birds are also the inspiration for Australian science communicator Dr. Karl Kruszelnicki. Honeyeaters are a large bird family (190 species) with a strong presence in Australia. The Common Myna is an aggressive invasive species. Thanks to Clare for introducing me to him. ” (HBW).
Birding by Impression is a conscious, deliberate method of identifying and recognizing birds based on the study and evaluation of “distinctive structural features and behavioral movements” and comparison with nearby and similar species. It is not a handbook, though it approaches species from a collective viewpoint. So say Kevin T.
Hugh Powell is a science editor at the Cornell Lab of Ornithology. Eight days with 20 of the world’s top birding guides looking for some 1,000 species and three dozen endemics. You can see as many hummingbird species as the folks at Magee Marsh are seeing warbler species—during 25 minutes on a Sunday afternoon.
It would make a great housewarming gift for the family that just acquired a yard, and is well-suited for giving to that one relative who always wants to ask you about the bird they saw last week that was about so big, and red, but with some black on it too.
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.
The single greatest challenge facing any book of science writing is balance. Otherwise, there would be no science writing, everyone would just go straight to the journals. That issue aside, though, this is a fascinating book which will engage not just birders, but most people who have any interest in nature or the science of the mind.
This is a delightful book, large (8-1/2 by 11 inches), filled with Sibley’s distinctive artwork and an organized potpourri of research-based stories about the science behind bird’s lives. They portray the nesting cycles of Mallard, Red-tailed Hawk, and American Robin, illustrating the various ways in which birds create families.
A family motel and passion for responsible ecotourism brought her home to the Oregon Coast where she and her husband, Erik, adventure and record a podcast ( Hannah and Erik Go Birding ), created in an effort to inspire others to get out and bird. Marion has a fascinating history with invasive species.
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. Here’s the thing.
And so, I learn from this page that each bird’s scientific name is unique, a combination of its genus and species names. In the earlier chapters, the maps illustrate bird species distribution. We are a BirdLife Species Champion!)
Even in the tropics there are few birds that excel some of our own in elegance and beauty of plumage and we have an unusually large number of species considering the smallness of the area they inhabit. ” (Woodward brothers, “Natal Birds”, 1899) The mighty Drakensberg Mountains run along the western boundary of KwaZulu-Natal province.
Starlings, they’ll dutifully explain, are ruthless invasives that have been responsible for the serious declines of several beloved native species, like the Red-headed Woodpecker ( Melanerpes erythrocephalus ) and the Eastern Bluebird ( Sialia sialis ). Good birding and happy drinking! Arrowood Farm Brewery: Starling Brett Farmhouse Ale.
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. Bird communication is a complex and evolving science.
A few families have a small number of eggs in the clutches, like gulls or cormorants. One North American species I am very familiar with is the Cassin’s Auklet , which ranges from the end of the Aleutian Islands to California. Some birds pump em out by the dozen in the hope that at least one or two survive.
It is a good place for South African birders, as several species are found here and nowhere else in South Africa, and it holds a small number of endemics that it shares with the Mozambique lowlands. It was pretty awesome to see so many tuskers, as well as families of elephants safe in their special park.
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.
Before my trip to Washington the only species of puffin I had ever seen in the wild was the puffin of the Atlantic Ocean, the appropriately named Atlantic Puffin. The first obstacle was getting to the general range of the species, which is the west coast from northern California to Alaska and across to Russia.* I love puffins.
Birkhead, the experienced storyteller who is also Emeritus Professor at the School of Biosciences, The University of Sheffield, author of multiple scientific articles as well as books of popular science, knows how to make it readable and fun. Colonialism and appropriation of knowledge is discussed in Chapter 6, The New World of Science.
I recently got the chance to read the book, 100 Heartbeats: The Race to Save Earth’s Most Endangered Species , written by Jeff Corwin. In this book, Corwin shares what he has learned as he travels the world to see first hand the species that are endangered. He currently resides with his family on an island in Massachusetts.
The field site I am assigned to is located in one of the most diverse ecosystems in the world and home to a particularly rich avifauna that numbers well over 500 species. Hundreds of riotously colored birds representing 14 species of macaws and parrots flock and frolic together in less than fifty meters of forest canopy.
