When a crow dies, the other crows investigate the cause of death (2015)
I believe ravens and crows are very similar, this is a personal (long, and not the great) story about a raven I messed around with in Yosemite National Park:<p>When I was up on north dome (not to be confused with half dome) there was a group of raven&#x27;s hanging out on the rocks watching us eat our late lunch. I had an apple core that I tossed to the side and watched as a raven warily tried to approach it. I walked over and grabbed the apple core before the raven could grab it so I could entertain myself teasing the raven for a bit before we started down the mountain. I started by putting my arm back ready to throw the apple and as I did that I noticed the raven kneel a bit as if getting ready to launch itself. I thought this was interesting as it showed it was anticipating me throwing the object based on my arm motion. As I relaxed my arm the bird also relaxed.<p>I tried grabbing a rock and again watched it brace itself to launch from the rock then tried switching the apple core and the rock behind my back and tossing the rock hoping the bird would dart after it thinking it was the core. The bird didn&#x27;t do as I expected and instead just watched me carefully never motioning for the rocks.<p>I tore a piece of the apple from the core behind my back and tossed it just as I had with the rocks and before the piece of apple even left my hand the raven leaped from the rock in its direction.<p>This blew my mind. Not sure how the raven knew it was a chunk of apple and not a rock.<p>I messed around with that particular raven for a good 10-15 minutes tossing various things in its direction, testing its reactions and trying to mess with its little raven mind. All I managed to do however was be impressed at its level of experience in dealing with Yosemite tourists such as myself.
