See those feathers? The skeleton they found was so well-preserved that scientists were able to examine the pigment cells in the feathers and compare them to those of modern day birds.
And they were able to do this with such accuracy that they know the coloration of this dinosaur. In life it looked something like this.
It just baffles me that we know the color patterns of an animal that has been dead for 161 million years
A planet has been found orbiting in the habitable zone of the closest star to earth, 4.2 light years away, named Proxima Centauri. The exoplanet, known as proxima b, has the mass of 1.27 earths but because of the shape of its orbit, the chances of it harbouring liquid water are fantastic. This vastly improves the chances that the planet sustains alien life.
i found out recently that the very first trees did not rot when they died because the microbes that decompose trees hadnt evolved yet…which makes sense but it’s weird to think about. this actually caused a huge change in the climate at the time and many of these trees turned into coal because of it…
like imagine a tree falling in the forest and the trunk just stays there for years and years with little change, and it only goes away when it is buried under dirt. that’s weird.
obviously they were still working on the worldbuilding back then
imagine all the lag from those trunks laying around. glad they patched those microbes in
So y’all talk about this like it’s a joke, but the exact same time is happening today with plastics, except today’s microbes are a bit quicker on the uptake. They’re still new at it, but Earth’s decomposers are hard at work learning how to eat polyester.
*ancient microbe voice* kids these days have it so easy. mutating to feed on new materials within a century? In my day it took us a millenium at minimum! we had to metabolize uphill in the snow both ways!
*even more ancient microbe voice* pfeh, typical oxygen-breather attitude. you think you had it rough but YOU have those fancy MITOCHONDRIA.
so the best thing about this is that bobcats, like just about every feline besides lions and domestic cats, are pretty solitary. they don’t really have friends. they aren’t really equipped to make friends.
domestic cats, on the other hand, do know how to make friends. they are friendly to the point that lots of feral cats live in colonies— the females hang out together, even raise kids together, and the males like to spend nonsexual time with their baby mommas. they groom each other, play around, and have a particular tail position to signal to one another— straight up with the tip curled— that they’re friendly and happy to see each other. cats learned how to be chill with each other in order to take full advantage of human food sources: an ancient granary supplies enough rats for a lot of cats, as does a modern lady with a big bag of frisky bits, so it would be a waste of time and energy for any one cat to try and stake the entire foodsource out for exclusive use. less fighting means more eating and resting which means a longer, nicer life and a lot more kittens.
so this stray cat, she obviously has no colony if she’s wandering around and sneaking into zoo enclosures, so she’s like ‘hey! there’s food here! what up, other cat, let’s be friends, let’s be friends and share that food’. and the bobcat is like ‘??????’ because actually wild cats are pretty cautious about initiating hostilities and anything new and aggressive makes them very worried. and the domestic cat is like ‘haha cool, ok, we’re friends now, big guy. no problems.’ and the bobcat is like ‘????? well…?? ok?’ and then they are friends.
the super interesting thing about most wild cat species is they don’t really have the capacity to make friends on their own, especially outside of sibling bonds, but, if someone comes along and does all the friend-making themselves, they’ll totally roll with it. zoo cats can get really attached to their caregivers— or, in this case, a very confident little calico demonstrating exactly why her species has been so darn successful over the last nine thousand years .
so anyway that is the best thing: bobcats are not equipped to make friends, but luckily for this bobcat this homeless lady did not give any shits and made friends anyway. and now they are both happy.
This is the world’s largest flying Engine of Murder marveling at the fact that it can actually have its tummy rubbed.
I feel like this is the next step up on “loose your fingers” roulette from petting a kittie’s tummy, but just below belly rubs for say a lion.
Can someone who knows birds better than I do tell me whether this eagle is as happy as it looks? Because I want it to be happy. It looks so happy. Bewildered by having a friend, but so happy.
Just popping on this thread to confirm: yes, the eagle is happy about the belly rubs. Golden eagles make this sound when receiving allopreening and similar affectionate and soothing treatment from their parents and mates. It’s the “I am safe and well fed, and somebody familiar is taking good care of me” sound. Angry raptors and wounded raptors make some pretty dramatic hisses and shrieks; frightened raptors go dead silent and try to hide if they can, or fluff up big and get loud and in-your-face if hiding isn’t an option. They can easily sever a finger or break the bones of a human hand or wrist, and even with a very thick leather falconer’s gauntlet, I’ve known falconers to leave a mews (hawk house) with graphic punctures THROUGH the gauntlet into the meat of their hands and arms, just from buteos and kestrels way smaller than this eagle. A pissed off hawk will make damn sure you don’t try twice whatever you pulled that pissed her off, even if she’s been human-imprinted.
If you’re ever unsure about an animal’s level of okayness with something that’s happening, there are three spot-check questions you can ask, to common-sense your way through it:
1. Is the animal capable of defending itself or making a threatening or fearful display, or otherwise giving protest, and if so, is it using this ability? (e.g. dog snarling or biting, swan hissing, horse kicking or biting)
2. Does the animal experience an incentive-based relationship with the human? (i.e. does the animal have a reason, in the animal’s frame of reference, for being near this human? e.g. dog sharing companionship / food / shelter, hawk receiving good quality abundant food and shelter and medical care from a falconer)
3. Is the animal a domesticated species, with at least a full century of consistent species cohabitation with humans? (Domesticated animals frequently are conditioned from birth or by selective breeding to be unbothered by human actions that upset their feral nearest relatives.)
In this situation, YES the eagle can self-defend, YES the eagle has incentive to cooperate with and trust the human handler, and NO the eagle is not a domesticated species, meaning we can expect a high level of reactivity to distress, compared to domestic animals: if the eagle was distressed, it would be pretty visible and apparent to the viewer. These aren’t a universally applicable metric, but they’re a good start for mammal and bird interactions.
Pair that with the knowledge that eagles reserve those chirps for calm environments, and you can be pretty secure and comfy in the knowledge that the big honkin’ birb is happy and cozy.
Also, to anybody wondering, falconers are almost single-handedly responsible for the recovery from near-extinction of several raptor species, including and especially peregrine falcons. Most hawks only live with the falconer for a year, and most of that year is spent getting the bird in ideal condition for survival and success as a wild breeding adult. Falconers are extensively trained and dedicated wildlife conservationists, pretty much by definition, especially in the continental USA, and they make up an unspeakably important part of the overall conservation of predatory bird species. Predatory birds are an important part of every ecosystem they inhabit. Just like apiarists and their bees, the relationship between falconer and hawk is one of great benefit to the animal and the ecosystem, in exchange for a huge amount of time, effort, expense, and education on the part of the human, for very little personal benefit to that one human. It’s definitely not exploitation of the bird, and most hawks working with falconers are hawks who absolutely would not have reached adulthood without human help: the sick, the injured, and the “runts” of the nest who don’t receive adequate resources from their own parents. These are, by and large, wonderful people who are in love with the natural world and putting a lifetime of knowledge and sheer exhausting work into conserving it and its winged wonders.
reblogged for excellent info, I’m so glad that big gorgeous birb really is as happy as it looks!
Today’s bit of positive activism: A reminder that, although the world may contain many bad and awful things, it also contains an enormous winged predator clucking happily as a human gives it a belly rub.
A special eye protein is helping birds to “see” Earth’s magnetic field! If that’s not cool, I don’t know what is.
The ability to see Earth’s magnetic field, known as magnetoreception, relies on the presence of specifically the blue wavelength of light. The complex process involves “radical” intermediate molecules which are sensitive to Earth’s magnetic field. The Earth’s magnetic field, as it relates to the direction the bird is facing, could alter the intermediate radical molecules differently, giving the bird a sense for where it is facing in relation to the Earth’s magnetic field.
While the exact way birds visualize Earth’s magnetic field is part of further investigation, scientists believe the Cry4 protein acts as sort of a filter over the bird’s vision. This filter would allow birds to see a sort of compass of the Earth and direct their migratory flights accordingly.
