With spring just around the corner (Mother Nature swears for real this time), North Americans are eagerly on the lookout for one of the earliest migratory harbingers of spring, the robin.
Wait, what? Robins are a Christmas bird! Hey, that's not a robin at all! [more inside]

The celebrated Australian author Colleen McCullough, probably best known for The Thorn Birds, has died at 77. McCullough's contribution to writing contributed well after her most famous book and she will be sadly missed. What has caused ire has been the way that her obituary was written in the Australian national newspaper, The Australian, where the second line refers to her physical beauty and weight. The Guardian compares this with other obituaries of people who do not have to be classified by weight or beauty or, as you would know them, men.
Birds on a wire....."One morning while reading a newspaper, Jarbas Agnelli saw a photograph of birds on an electric wire. He cut out the photo and was inspired to make a song using the exact location of the birds as musical notes. He was curious to hear what melody the birds created."
"A remarkable international effort to map out the avian tree of life has revealed how birds evolved after the mass extinction that wiped out the dinosaurs into more than 10,000 species alive today. More than 200 scientists in 20 countries joined forces to create the evolutionary tree, which reveals how birds gained their colourful feathers, lost their teeth, and learned to sing songs." Via iO9.
Birds, like quite a few other animals, can exhibit Gynandromorphism. Homosexual behavior in birds is also common. The phenomenon of avian spontaneous sex reversal has been well-documented, starting with Aristotle. Now modern researchers have uncovered yet another way in which birds are hacking sex roles: scientists think white-throated sparrows may actually be evolving a second pair of sex chromosomes.
"A few days ago, my son, Lucas, and I took the train to Prague for his school break. Usually, when I visit a city, my first port of call is whatever passes for a botanical garden but when he told me that Prague’s zoo contained not only giant salamanders but also two pairs of shoebills, I could not resist the temptation..."

A team of researchers, including University of Edinburgh paleontologist Stephen Brusatte and Swarthmore College Associate Professor of Statistics Steve C. Wang, cataloging 853 skeletal characteristics in 150 dinosaurs and analyzing the rate at which these characters change, and they found that "there was no grand jump between nonbirds and birds in morphospace." In other words, birds didn't suddenly come into existence, but evolved, bit by bit, or characteristic by characteristic. But when birds were finally a thing, they went crazy. "Once it came together fully, it unlocked great evolutionary potential that allowed birds to evolve at a super-charged rate."

"It was always assumed that V-formation flight was learned from the adult birds. But these guys are all the same age and they learned to fly from a human in a microlight. They learned V-formation flying from each other. National Geographic reports on some of the fascinating intricacies of the V formation observed in migrating birds.
Invertebrate numbers nearly halve as human population doubles. The decline of birds might have something to do with this recent news that half the insects (and spiders, crustaceans, slugs, worms) are gone.
They saw "birds entering the solar flux and igniting, consequently become a streamer," for the smoke plume that comes from birds that ignite in midair. BrightSource concentrated solar plant is a "mega-trap" for wildlife, with the bright light of the plant attracting insects, which in turn attract insect-eating birds that fly to their death in the intensely focused light rays. Estimates range as high as one streamer every two minutes at a single plant, though this is disputed. A Federal report (PDF) is "occasionally gruesome".

Hummingbirds have been slow to give up their secrets, but slowly, we've learned to understand them.
Thanks to a certain resemblance to an insect, the hummingbird is known in French as “oiseau mouche” (fly bird). Its fondness for the calyxes of blossoms has inspired the Portuguese names “beija flor” (flower kisser) and “chupa flor” (flower sucker), and the related Spanish “pica flor” (flower poker). In other languages, hummingbirds are known as “Kolibri,” a word likely of Caribbean origin, or Trochilidae, their scientific name (which was provided by Carl Linnaeus and, curiously, seems to relate to a different bird — a type of kinglet called “trochilus” by the ancient Greeks). These inventive names reflect the wonder and enigma that surrounds these creatures and the peculiar abilities and proclivities that set them apart from other birds.[more inside]

Birdly: An Attempt to Fly. "‘Birdly’ is an installation which explores the experience of a bird in flight. It tries to capture the mediated flying experience, with several methods. [...] Visualized through HMD (Oculus Rift) the participant is embedded in a virtual landscape where his body is the body of a Red Kite. The whole scenery is perceived in the first person perspective of a bird. To intensify the embodiment we include additional sonic, olfactoric and wind feedback. Soundwise you perceive only the roaring of the wind and the flaps of the wings." [more inside]

From 1851 to 1858, Henry David Thoreau noted a number of natural occurrences in detail, including the first flowering dates for over 500 species of wildflowers in Concord. Additionally, Alfred Hosmer, a botanist in the same area, had recorded the flowering dates of over 600 species of wild plants in 1878 and from 1888 to 1902. With that data, Richard Primack, a biology professor at Boston University, and fellow researcher Abraham Miller-Rushing spent years aligning old plant names with current names to study the change flowering patterns from the recorded past to present. Their phenological study concluded that plants in Concord, on average, are now flowering 10 days earlier than they were in Thoreau's time (full article for the journal BioScience). [more inside]

Dennis Hlynsky is a professor of film and animation at RISD whose most recent work, titled Small Brains on Mass, looks at bird behavior, particularly how they interact when flying in groups. To better understand how flying as a flock is achieved, Hlynsky filmed the birds and then stacked the images on the same frame for a set number of frames, the results show each bird’s flight as a trail, but synchronized with the flock. The results are often pure poetry. [more inside]
Snowy owls are irrupting across the upper Midwest and down the East Coast as far as the Carolinas in what could be the largest such irruption in at least 20 years. They're here because there were a lot of lemmings in the Arctic last year, and so snowy owls made a lot of snowy owls. This year? Not so many lemmings, and so many of them have come south in search of food. [more inside]

"My subject is a barren one – the world of nature, or in other words life; and that subject in its least elevated department, and employing either rustic terms or foreign, nay barbarian words that actually have to be introduced with an apology. Moreover, the path is not a beaten highway of authorship, nor one in which the mind is eager to range: there is not one of us who has made the same venture, nor yet one Roman who has tackled single-handed all departments of the subject."Naturalis Historia was written by Pliny the Elder between 77 and 79 CE and was meant to serve as a kind of proto-encyclopedia discussing all of the ancient knowledge available to him, covered in enough depth and breadth to make it by a reasonable margin the largest work to survive to the modern day from the Roman era. The work includes discussions on astronomy, meteorology, geography, mineralogy, zoology and botany organized along Aristotelian divisions of nature but also includes essays on human inventions and institutions. It is dedicated to the Emperor Titus in its epistle to the Emperor Vespasian, a close friend of Pliny who relied on his extensive knowledge, and its unusually careful citations of sources as well as its index makes it a precursor to modern scholarly works. It was Pliny's last work, as well as sadly his sole surviving one, and was published not long before his death attempting to save a friend from the eruption of Mt. Vesuvius that destroyed Pompeii and Herculaneum, famously recounted by Pliny's eponymous nephew Pliny the Younger.

Megapode, Greek for "large foot," refers to refers to 12 species of Australasian chickenlike birds (order Galliformes), which have small heads compared to their bodies, and large feet. They are also known as Mound Builders, or Incubator Birds, as they bury their eggs in some warm material, most commonly fermenting or decomposing plant matter. But on Sulawesi island in Indonesia, Maleos bury their eggs in sun-baked or volcanically heated sands, then depart. The young hatch from their large eggs (5 times the size of chicken eggs), then dig out of their sandy incubators and walk or fly away. If you can't make it to Indonesia to see the birds in person, you can also visit the Wildlife Conservation Society's Bronx Zoo to see their 9 Maleos, or check out their video about Maleos and the zoo's breeding program.

Cocks (almost) don't have a penis, a trait common to 97% of bird species, but they can grow one when the expression of the Bmp4 gene is prevented. The expression of this gene causes the percursor of the phallus in the chick embryo to undergo apoptosis (cell death) and Bmp genes are also involved in 3 other bird traits: feather development, toothlessness and beak shape. In penis-less bird species, copulation requires a sex maneuver nicknamed the cloacal kiss (in French) which requires a full cooperation of the female (3 min of tender parrot sex). In species where males have a penis, like ducks, females are less lucky: the coevolution of the rather convoluted morphology of male and female genitalia has been hypothezised to occur through sexual conflict [many previouslies]. The evolutionary mechanisms that drove phallus reduction in most birds species are still unknown.
