it was me using simpler phrasing in part because i couldn't remember the details very well

but i was referencing an experiment where researchers wearing "threatening" and "non-threatening" masks interacted with and marked crows, and other crows in that area who they had not interacted with recognized them later. https://www.sciencedirect.com/science/article/abs/pii/S0003347209005806 (however that crows tell stories is, as far as i know, only a popular interpretation, their official conclusion, at least of this experiment, is that crows are capable of long term memory retention and fine-feature discrimination)

and simple observations suggesting prairie dogs may have a very advanced language - which went viral in my online circles with people joking that they gossip about us, which probably just stuck with me because i think it would be very cute

i personally believe that animals most likely do communicate among each other and the complexities of their languages just varies, even if most are not obviously very complex. my personal beliefs are that communication is complicated and can happen through more than verbal/vocal language, animals are clearly capable of feeling complex emotions and pain which is enough for me personally to consider them sentient, and (again this is just my personal belief) i believe it's probably better to treat them as if they are sentient until proven otherwise than the opposite. and just to be upfront and honest with others and myself about my possible biases, i believe in the Buddhist concept of Saṃsāra, and believe that that we're all a part of the same cycle of death and rebirth

edit found some more info:

Researchers noticed that the animals made slightly different calls when different individuals of the same species went by. ... so they conducted experiments where they paraded dogs of different colours and sizes and various humans wearing different clothes past the colony. They recorded the prairie dogs' calls, analyzed them with a computer, and were astonished by the results.

"They're (prairie dogs) able to describe the colour of clothes the humans are wearing, they're able to describe the size and shape of humans, even, amazingly, whether a human once appeared with a gun," Slobodchikoff said. The animals can even describe abstract shapes such as circles and triangles.

Also remarkable was the amount of information crammed into a single chirp lasting a 10th of a second. "In one 10th of a second, they say 'Tall thin human wearing blue shirt walking slowly across the colony.'"

“They know your body type. The way you walk,” Dyer said. “They’ll take their young down and say: ‘You want to get to know this guy. He’s got the food.’ ”

Scientists have known for years that crows have great memories, that they can recognize a human face and behavior, that they can pass that information on to their offspring.

that article also mentions that crows have been observed to make and use tools, which is something i knew but forgot to mention and is interesting and feels relevant to this conversation
