Cute illustrations of bread birds

Twitter user @fuguhitman has recently done a series of bread birds with portmanteau names like Croisswant, Breadolark, Pidgingerbread, Bagull, and Crownut. Now I’m hungry and I want to go sit in a quiet forest with binoculars.

Elegantly carved birds immersed in watercolor paint

Mexican artist Moisés Hernández makes these simple, graceful bird sculptures by having a machine carve the shapes out of ash and filling in the plumage by hand-dipping them in watercolor paint, as if decorating Easter eggs.

In an attempt of generating a balanced dialogue between machine made and handmade objects, we made soft and continuous shapes milled with CNC technology contrasted with handmade painting done by immersion in coloured water, an experimental technique we developed for this project, which gives the birds a unique personality. This technique of painting allows to achieve an interesting texture of intersections and transparency made by layers of colour that resembles the plumage of birds. The amount of colour, hue and the way sections cross one another depends on the time and position the wood is plunged.

John James Audubon’s five mystery birds

Over a period of thirteen years beginning in the 1820s, John James Audubon painted 435 different species of American birds.1 When he was finished, the illustrations were compiled into The Birds of America, one of the most celebrated books in American naturalism. Curiously however, five of the birds Audubon painted have never been identified: Townsend’s Finch, Cuvier’s Kinglet, Carbonated Swamp Warbler, Small-headed Flycatcher and Blue Mountain Warbler.

These birds have never been positively identified, and no identical specimens have been confirmed since Audubon painted them. Ornithologists have suggested that they might be color mutations, surviving members of species that soon became extinct, or interspecies hybrids that occurred only once.

The specimen that Audubon used to paint Townsend’s Bunting is now in the Smithsonian Museum of Natural History, identified as Townsend’s Dickcissel, but no bird exactly like it has been reported, Dr. Olson, an authority on Audubon’s work, noted in an email. Ornithologists suggest that it is either a mutation of the Dickcissel or a hybrid of Dickcissel and Blue Grosbeak, she said.

And that’s not counting the ones he got wrong for other reasons:

And indeed, there are several birds painted and explained in Birds of America that are not, in fact, actual species. Some are immature birds mistaken for adults of a new species (the mighty “Washington’s Eagle” was, in all likelihood, an immature Bald Eagle). Some were female birds that didn’t look anything like their male partners (“Selby’s Flycatcher” was a female Hooded Warbler).

Audubon also painted six species of bird that have since become extinct: Carolina parakeet, passenger pigeon, Labrador duck, great auk, Eskimo curlew, and pinnated grouse. Here’s his portrait of the passenger pigeon:

Audubon Passenger Pigeon

There were an estimated 3 billion passenger pigeons in the world in the early 1800s — about one in every three birds in North America was a passenger pigeon at the time. Their flocks were so large, it took hours and even days for them to pass. Audubon himself observed in 1813:

I dismounted, seated myself on an eminence, and began to mark with my pencil, making a dot for every flock that passed. In a short time finding the task which I had undertaken impracticable, as the birds poured in in countless multitudes, I rose and, counting the dots then put down, found that 163 had been made in twenty-one minutes. I traveled on, and still met more the farther I proceeded. The air was literally filled with Pigeons; the light of noon-day was obscured as by an eclipse; the dung fell in spots, not unlike melting flakes of snow, and the continued buzz of wings had a tendency to lull my senses to repose… I cannot describe to you the extreme beauty of their aerial evolutions, when a hawk chanced to press upon the rear of the flock. At once, like a torrent, and with a noise like thunder, they rushed into a compact mass, pressing upon each other towards the center. In these almost solid masses, they darted forward in undulating and angular lines, descended and swept close over the earth with inconceivable velocity, mounted perpendicularly so as to resemble a vast column, and, when high, were seen wheeling and twisting within their continued lines, which then resembled the coils of a gigantic serpent… Before sunset I reached Louisville, distant from Hardensburgh fifty-five miles. The Pigeons were still passing in undiminished numbers and continued to do so for three days in succession.

100 years later, they were all dead. Which may have had at least one interesting consequence:

But the sad echo of the loss of passenger pigeons still reverberates today because its extinction probably exacerbated the proliferation of Lyme disease. When the passenger pigeons existed in large numbers, they subsisted primarily on acorns. However, since there are no pigeons to eat acorns, the populations of Eastern deer mice — the main reservoir of Lyme disease — exploded far beyond historic levels as they exploited this unexpected food bonanza.

  1. Interesting note: Audubon financed this project through a subscription plan. Each month or two, each subscriber would receive a set of five prints and the proceeds covered the costly printing process and Audubon’s nature travels.

Migration map of American birds

Bird migration map

From the Cornell Lab of Ornithology, an animated map of the yearly migratory patterns of 118 bird species in the Western Hemisphere.

La Sorte says a key finding of the study is that bird species that head out over the Atlantic Ocean during fall migration to spend winter in the Caribbean and South America follow a clockwise loop and take a path farther inland on their return journey in the spring. Species that follow this broad pattern include Bobolinks, Yellow and Black-billed cuckoos, Connecticut and Cape May warblers, Bicknell’s Thrush, and shorebirds, such as the American Golden Plover.

“These looped pathways help the birds take advantage of conditions in the atmosphere,” explains La Sorte. “Weaker headwinds and a push from the northeast trade winds as they move farther south make the fall journey a bit easier. The birds take this shorter, more direct route despite the dangers of flying over open-ocean.”

The map was created with data from eBird, a database of crowdsourced bird sightings. They also created a follow-up map which labels each of the species. Look at how far Baird’s Sandpiper (#5) flies…all the way from central Argentina to Northern Canada and back. (thx, kevin)

According to paleontologist Gareth Dyke, “fossil evidence that [predatory] dinosaurs were feathered is now ‘irrefutable’”. Digitally remastered Jurassic Park can’t be too far down the road.

The club-winged manakin sings by playing its feathers like a washboard. Crickets do this, but the manakin is the first vertebrate observed to do it.
