A limited palette Microraptor for any of you still awake. I might sell prints of this somewhere, but I”m still deciding on the details u.u
Heron tries to swallow giant lamprey. Chokes. Dies. Second heron tries same trick. Also chokes. Also dies.
Original Tet. Zoo article HERE.

This is great. Also, I’m curious what will happen to the resolution when I re-blog this.
I thought so too, person whom I don’t know.
I thought so too.
I just shaved. touch my leg.
Australian Darter (Anhinga novaehollandiae)
Also known as the Australasian Darter, the Australian Darter is a species of Anhinga native to Oceania and Indonesia. Like its American and African relatives this species is an aquatic hunter, darting through the water and spearing fish with its sharp bill. They can often be seen perched out of water fanning out their wings, this is because their feathers aren’t waterproof so they must keep dry to remain buoyant.
The flightless dodo, Raphus cucullatus, was native to the island of Mauritius, in the south-western Indian Ocean. On 20 September 1598, a Dutch fleet commanded by Admiral Wybrant van Warwijck found a channel through the reef encircling Mauritius, and initiated the permanent settlement of the island. Less than a century later, the dodo was extinct, and other species followed rapidly.

Red-capped Plover (Charadrius ruficapillus)
Also known as the Red-capped Dotterel, the Red-capped Plover is a small species of plover found throughout Australia and New Zealand. Like most shorebirds the red-capped plover is often found on coastal areas like mudflats, wetlands ,bays and beaches. Where they comb the sands for small invertebrates that are buried in the sand. The plover only gets its famous red cap during the breeding season, as it is used to attract females.
Valentine’s Day Tips From a Tragopan
Trying to catch the eye of that special someone? Then you need these moves, custom-evolved to win them over fast.
First, get your crush’s attention by pecking around on the ground. This will make them curious. But then, immediately hide behind a log. You’re putting on a show here—you don’t want to give everything away!
Next, inflate your rubbery blue horns and unfurl your flappy bib. Bob up and down a bunch of times to make sure that they’re fully deployed. You need to look your best!
Then start with the frenetic clicking. This will signal to your love interest that you’re ready to take things further. (Honest communication is the key to any successful romantic pursuit.)
When you feel ready, rear up and rush forward, displaying yourself in all your naked glory to the object of your affection. Remember: You are confident. You are fabulous. You have inflatable rubbery horns. You’ve got this.
If it doesn’t work the first time, try again. Try flapping harder. Click some more. You’ll have a valentine in no time, guaranteed.
It makes me so sad that we may never know how many dinosaurs did this shit

These Birds Are Dying So Rich, Powerful Men Can Improve Their Sex Lives
According to myth, though not supported by any scientific studies, the meat of houbara bustards has aphrodisiac qualities.
by Richard Conniff
Every year beginning in November, the tawny, mottled birds known as houbara bustards make their annual migration southwest from their breeding grounds in Kazakhstan, China, and Mongolia. Most end up in the deserts of Pakistan.
Another migration, by some of the richest and most powerful men in the world, soon follows them there, armed with almost every kind of hunting weapon imaginable.
Well, no drones, so far. But for Pakistani environmentalists, this uncontrolled slaughter by foreign powers is almost as enraging. The hunters often deploy a trained falcon to swoop in on a houbara and slam it to the ground, the victim reduced to a violent flapping of wings and feathers torn loose from its flesh. (They preserve the memory in videos like this.) They also use shotguns on houbaras and target Siberian cranes and almost any other living thing foolish enough to come in range. A 2011 estimate—a guesstimate, really—put Asia’s houbara population at no more than 55,000 birds and sharply declining…
A CROW TRIED TO GO IN OUR CLASSROOM AND HE HAD A PEN
yes hello i am here to learn geometries
That crow is more prepared than some of my students.
You’ve all just like, completely skipped over the possibility that this crow has seen people using pens in this room, found one, and is trying to return it. There’s been videos of crows picking up sweet wrappers and stuff and placing them in bins after seeing humans put their litter in bins. I really do believe that this crow is trying to return the pen and that is ADORABLE AS HELL.
THEY ARE SO SMART I LOVE THEM

Valentines from an evolutionist’s perspective.
This incredibly cool new study by Gossi et al, published today in PLOSone, has researched whether chickens walk differently if they have a long, heavy tail, reminiscent of the type of tail present in non-avian dinosaurs. Giving them such a tail artificially (while controlling for weight) actually changes their gait significantly, giving them more hip-driven locomotion and less knee-driven as in modern birds. Check out the paper, it’s open-access.
From the abstract:
Birds still share many traits with their dinosaur ancestors, making them the best living group to reconstruct certain aspects of non-avian theropod biology. Bipedal, digitigrade locomotion and parasagittal hindlimb movement are some of those inherited traits. Living birds, however, maintain an unusually crouched hindlimb posture and locomotion powered by knee flexion, in contrast to the inferred primitive condition of non-avian theropods: more upright posture and limb movement powered by femur retraction. Such functional differences, which are associated with a gradual, anterior shift of the centre of mass in theropods along the bird line, make the use of extant birds to study non-avian theropod locomotion problematic. Here we show that, by experimentally manipulating the location of the centre of mass in living birds, it is possible to recreate limb posture and kinematics inferred for extinct bipedal dinosaurs. Chickens raised wearing artificial tails, and consequently with more posteriorly located centre of mass, showed a more vertical orientation of the femur during standing and increased femoral displacement during locomotion. Our results support the hypothesis that gradual changes in the location of the centre of mass resulted in more crouched hindlimb postures and a shift from hip-driven to knee-driven limb movements through theropod evolution. This study suggests that, through careful experimental manipulations during the growth phase of ontogeny, extant birds can potentially be used to gain important insights into previously unexplored aspects of bipedal non-avian theropod locomotion.
