why is this about to make me sob

I've seen posts going around claiming that petting animals is basically tricking them into thinking they're being groomed, and it's bugging me because, like, there's no trickery afoot. Petting and scritching are grooming activities. They help to dislodge loose fur and foreign objects and more evenly distribute protective oils, among other things. Primates are social groomers, and the human impulse to scritch is the legacy of our primate ancestors. We see an animal we like, even a dangerous one, and the monkey brain says "groom that thing".

Frogs eat insects, right? And sometimes other invertebrates, and maybe little vertebrates like tiny fish or tadpoles or smaller frogs. But this is one of those neat cases where you have a total departure from what's expected.

While Xenohyla truncata (aka "Izecksohn's Brazilian tree frog") does eat some invertebrate prey, it also deliberately seeks out fruit. Given that it lives high in the canopy of the rain forest amid bromeliads, it's not out of the realm of possibility that this started out as supplementing a normal frog diet with high-calorie fruit in tough times, and evolution favored those that were able to make better nutritional use of this opportunity.

It reminds me of the (mostly) vegetarian spider Bagheera kiplingi, and how primarily herbivorous ungulates like horses and deer will opportunistically eat baby birds or gnaw on carrion and bones. While we can make generalizations about the dietary habits of certain groups of animals, there are exceptions to every rule. And I personally find the existence of these unique outliers to be part of what makes the natural world so utterly fascinating--no matter how much we learn, there are always more surprises to discover.

Do you have any cool bird facts

female raptors (eagles, hawks, falcons, etc) are larger than male raptors in pretty much all species. this happens even in groups not closely related to each other (ex: hawks and falcons), so its beneficial enough in their niche that its evolved independently a few times, though its unsure exactly what that benefit is atm (bc unlike males being larger in a lot of mammals, female raptors dont make a habit of fighting each other or using size to attract mates as far as we know). ex: heres a male and female Cooper's Hawk

somewhat mentioned above but falcons are more closely related to parrots than they are to hawks

Gray Catbirds and American Robins have been witnessed raising young in the same nest at the same time. In one instance (reported by Mulvihill and Murray), they were recorded caring for the young of both species in the nest, and when the Catbird young fledged, the adult Catbirds continued to provide food for the not-yet-fledged Robins. heres a pic of the nest from the report

the worlds oldest known bird as of 2024 is a wild Laysan Albatross named Wisdom who's 72-73 years old (at minimum, we dont actually know her birth date, just that she was at least 5 years old when she was banded in the 50s) and still raising chicks. here's her with one of her chicks

also Albatrosses have wingspans of up to 3.5m/11.5ft and have been recorded flying 49,700 miles without touching land (they do land in the water to eat tho)

this is from personal experience but if you walk around in a north american grassland for long enough, you Will get jumpscared by a Mourning Dove bc they make their nests on the ground in the grass and like to hang out on the ground in the grass and they also like to wait until youre right overtop of them to freak out and fly away from you

Bald Eagles don't get their fully white heads and tails until theyre about 5 years old

A lot of birds have been observed incorporating cigarette butts into their nests, and a study in Mexico on House Finches found that this actually results in drastic decreases in parasites affecting young compared to nests without them

Cedar Waxwings (and Waxwings in general) just look so smooth. they look like someone airbrushed them. look at this shit

in Jacanas, females lay eggs in multiple males' nests, and then the males raise the young by themself. Also they carry their babies under their wings like this

Horned Guan. Theyre endangered and live in a small area of central america. both the males and females have the little horn fez, the males just have taller ones

The berry pickers creed

I will leave unripened berries untouched

A ripe berry need only be negotiated with, not fought

I will reasses my surroundings after every step, for my new perspective could reveal a berry patch previously hidden to me

The plant gets excited and happy when a barry is picked

The bug is not to be feared or killed, but gently celebrated, for it facilitated in the creation of the beloved berrys

I will not allow myself to be bullied by sharp thicket and I will retrieve even the most protected barry

sometimes people try to tell me that scientists are paragons of rationality and I have to break it to them that I have yet to work in a lab that didn’t have at least one weird secret shrine in it

I am super against light pollution, and have been for decades

but I am also super annoyed by the way it's framed as "without light pollution you can see how beautiful the night sky is" way more prominently than it's framed as "hey, did you ever stop to think of how much energy/resources/money are literally wasted by having so much light shine up into the sky?"

so people get the idea that light pollution can only be remedied by eliminating all night-time light, which would make being outside at night very inconvenient, instead of by making night-time light shine only on the ground where, y'know, the people who need it are
