| Jul 13, 2023 at 22:34 | comment | added | Jon Custer | @WeatherVane - to me it reads as opportunistic - ravens find it first, bald eagles join in, but both need coyotes to show up to rip the carcass apart more to expose more stuff. It does not read that the 'plan' it, it just happens that way and they each take advantage of the others. | |
| Jul 13, 2023 at 22:32 | comment | added | Weather Vane | @JonCuster good find. But does that equate to cooperation or to opportunistic behaviour subject to their respective skills & abilities in the presence of other competitors? | |
| Jul 13, 2023 at 21:08 | comment | added | Jon Custer | The paper bioone.org/journals/journal-of-raptor-research/volume-52/… includes "Bald Eagles relied on ravens for discovery and sentinel duties, whereas both species depended on coyotes for accessibility." but that is about interacting on carcasses. | |

The author's research does find that ravens differ in intelligence, although it says nothing about differences in patience, perseverance, stealthiness. Maybe ravens, through long observation, have concluded that humans are unobservant and so a little easing of position will go unnoticed. Or maybe the raven really was warning the woman. | |
| Jul 12, 2023 at 19:54 | comment | added | Weather Vane | If the raven was intelligent enough to lead a cougar to "lie in wait", i.e. to a place where it anticipated a human would pass, surely it would also know that it must not tip off the human to the danger... I do know that animals can lead you: when I arrived at a relative's house one of their dogs clearly wanted me to follow it to where the senior dog was sleeping; in the movies a horse leads someone to where the rider fell; etc. | |
