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. So, for example, humans are apes. The paper that just came out in science has the following spectacular conclusion.
It also summarizes the vagrancy status of every bird family in the whole wide world, which makes it fun to read as well as superbly educational. Today’s vagrant could be tomorrow’s resident, a change that is visibly happening with, for example, the Clay-colored Thrush in southern Texas. It’s not always easy reading.
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. .”
For example, many photos are shot in poor light, obscuring the true colours. 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.
I would be more apt to accept the science of BBI if the science of hemispheric brain functions was not subject to so much misconceptions and simplification.* It is a common, for example, to say that Forster’s Tern has whitish wings and Common Tern has darker gray on the wings.
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.
How to choose bird feeders; how to make nutritious bird food; how to create a backyard environment that will attract birds; how to survey your feeder birds for citizen science projects; how to prevent squirrels from gobbling up all your black oil sunflower seed (sorry, none of that works). The story of Duncraft is a good example.
Their taxonomic affinities have caused great confusion and debate amongst ornithologists; they were originally assigned to the thrush family, then Old World warblers before being shifted to babblers (the last mentioned a common dumping-ground for any aberrant passerines).
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. Fossil Evidence for Evolution of the Shape and Color of Penguin Feathers Science, 330 (6006), 954-957 DOI: 10.1126/science.1193604
It’s relatively easy to classify birds into family groups based on physical characteristics. We view them as our enemies when they eat our crops and as an extension of our family when we see them at our feeders. Remarkably, there are 59 bird families that have very little cultural significance; these are listed in Appendix III.
For example, I was going to add “no tail” to the list of features above, what all frogs share, when I remembered that there are indeed a small family of Tailed frogs, four species in New Zealand and two in North America (though, the tails are quite tiny). If you don’t live near a science museum, then read this chapter.
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. In every chapter, Nate makes clear that you can go further and deeper, but you don’t have to. And you will still be a birder.
If only you could make fine adjustments to the expression of existing DNA you could hatch a dinosaur, starting with, for example, a turkey. The second thing they did was to interfere with the genetic pathways in some chickens, which produced a chicken with beaky bits that were more like snouty bits found in, for example, a Alligator.
But that is science in hierarchical institutions). Confusingly, while there are more than 50 species in the fantail family, the Yellow-bellied Fantail is not one of them. Instead, it is a member of the family of fairy-flycatchers, which sounds vaguely homophobic but probably is not.
For example, take the Mississippi Kite (above), photographed at the Dairy Mart Ponds in Tijuana River Valley, between San Diego and the Mexican border. Not only is it a very impressive citizen science project that manages to marshal the legions of birders around Canada and the U.S., Let’s get to it then.
A few families have a small number of eggs in the clutches, like gulls or cormorants. The species readily takes to nesting in small artificial boxes, and the scientists of PRBO Conservation Science have over 450 such boxes scattered across the island to monitor the species.
In a little less than two weeks my family and I will be enjoying a long weekend on the Yucatan Peninsula of Mexico. But rather than just use field guides for visual field marks and xeno-canto for sounds I have discovered a fun way to help me prepare that also contributes to citizen science in a small but noticeable way.
This is more than eBird reports–a checklist generated from the citizen science database lists only 1,413 species. The song of the Amazonian Antshrike, for example, is “an even pitched, fast (9-11 noes/sec), slightly accelerating series of hollow, popping notes that get louder; occ. slightly rising-falling in pitch and pace.
As you can easily judge from the dullness of this information, it is not something I made up but rather an appalling example of nepotism in the naming of birds. If you have always wondered what the minimum anesthetic concentration for isoflurane and sevoflurane for the Crested Serpent-eagle is, science has an answer.
Thankfully, English names are listed by whole name; for example, Stygian Owl is listed as “Stygian Owl”, under S. With so many book indexes listing species under family name, I am thankful that the decision was made NOT to list all 39 owl species under the heading “Owl.”
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.
Change Of Heart provides science-based answers to many questions that are hotly debated among animal activists. For example, why is it so hard for our family members and co-workers – many of whom have companion animals that they love – to cut cruelty from their diets and go vegan? In the author's words.
They used Great T**s from non-urban and urban areas, and mixed them up through breeding, to rule out any possible family history of telomere length. In this study, published in the journal Proceedings of the National Academy of Sciences, a group of juvenile zebra finches was allowed to interact with an adult. Here’s the problem.
Bird communication is a complex and evolving science. Ballantine and Hyman explore how birds communicate and summarize studies on how that communication functions in diverse bird families all over the world. Bird communication is much broader than just vocalization, something I tend to forget.
The World’s biggest citizen science wildlife count takes place this weekend. It is marketed as a family activity and limited to one hour to allow for young attention spans. Greenfinch populations have plummeted as Goldfinch numbers have soared for example. How easy is that?
Clearly, author Phyllis Limbacher Tildes, the author of 24, soon to be 25, children’s books, is also a birder (and a little research brings up a presentation she gave at Ogeechee Audubon, Georgia with the biographical information and she and her family “love watching birds and wildlife seen near their lagoon on Skidaway Island.”
Written in a friendly, inclusive style quietly grounded in science, How to Know the Birds is an excellent addition to the growing list of birding essay books by talented birder/writers like Pete Dunne and Kenn Kaufman.
Second, many of these performers were married and the idea of travel, even incentive travel, meant their families would be on their own for a few days. In the previous example, the company’s leaders assumed their high performers would be as engaged in the company’s operational effectiveness as were they.
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. This isn’t a bad thing, it’s just a very different kind of book than popular books about bird behavior, which rely on story as much as science.
I happen to be particularly fond of turtles because my family has taken care of a small box turtle for 30 years (beware–turtles are extremely low-maintenance pets but will outlast your child’s youth and probably your life). Or that tortoises and terrapins are considered part of the turtle family. Lovich and Whit Gibbons.
Birds & Flowers: An Intimate 50 Million Year Relationship is to highlight other bird families that pollinate. This is not, it should be noted, the sort of book in which a journeyman nature writer distills the ins and outs of some discrete marvel of natural or physical science to a lay readership. Based in Denmark and the U.K,
For example, while we’re used to ‘seasonality,’ observing damselflies and dragonflies in warmer months, rainfall is “the most significant variable” in the tropics (p. Species are arranged by family and genus along taxonomic lines, but not always in accordance with the very latest molecular DNA research.
And if you look into it enough, it presents a classic case where science can fail us. I believe in science. Science is based on logic and evidence, which I think is a very respectable way to look at the world. But what many people fail to realize, and too often scientists themselves, is that science is elastic.
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.&# Flight is an example.
In addition, many of the numbers and examples given for NYC areas beyond the Bronx represent species observed in Central Park in Manhattan and Prospect Park in Brooklyn. This is a project that clearly spanned decades. The authors say they want to “place Van Cortlandt Park’s avifauna in a New York City park perspective” (p.34).
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.
These run the range from birds like Barnacle Goose and Little Egret, which are rare but do show up in North America every few years (actually, lately it’s been every year) to birds whose sightings in North America are so few that they’re legendary–Western Reef-Heron and Corn Crake are two examples. This is not unusual.
The famous Verreaux family who made several expeditions into the province through the 1820’s and 1830’s procuring specimens for rich collectors. Gurney’s Sugarbird was discovered by the Verreaux family and named after wealthy English banker and amateur naturalist John Gurney from Norwich. Image by Hugh Chittenden.
Itcher birds, migratory members of the tern family. But in the vast in between where most birds exist there are all sorts of contradictory examples. Little tiny birds with their little tiny wings and high daily energetic demands fly zillions of miles, while larger birds migrate shorter distances, for example. Image source.
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. The book focuses on two listing events: her 2012 Louisiana Big Year and her 2016 Louisiana 300 Year.
The thousands of hours of observations that have been added up over the years would not have been possible without the help of the many volunteers and assistants who have offered their time and energy in the cause of science and conservation. Volunteers are one of the most important aspects to the project.
Of the Central Flyway states, Nebraska alone holds out in protecting the cranes, having proven by its longstanding Festival of the Cranes in Kearney that a crane is worth infinitely more alive and purring in the sky with its family than thudding, broken and bleeding, into a cornfield. Tennessee found that out in January.
That fallacious family name seems to have encouraged all manner of knaves, dunderheads, and miscreants when time came to label species. Consider some examples: NAMED FOR OTHER BIRDS. For example, the legendary ornithologist Alexander Wilson happened upon in his broad travels a warbler previously undescribed by science.
This is also where Johnson starts talking about the cost of the theft to the Museum and to science. The Flame Bowerbird, for example. He says he is motivated by what he has learned from the curators about the skins importance to science, but he is also clearly irritated by the fact that Rist has gotten off so lightly.
