Another CAG story. (Well, two more actually...)
It's not just cognition, it's the degree of empathy these creatures have...
One day, after a terrible day at work, I came home on a major downer. My CAG climbed down from the big playstand and waddled over to me, wanting to be picked up. We talked a little bit, and played one or two of our favorite games, but he could tell I was upset...
So, he climbs down my leg, and waddles back to the bird room, climbs up into his cage and begins digging through his food bowl. He pulls out a cashew (his favorite nut!) He then proceeds to climbs down from his cage and waddle back to me in the living room, signaling that he wanted to be picked up. This time, he set the nut down in my hand, and told me "It's okay. You're a good boy! And gave me a kiss beak to lips... Then he climbed down my pants leg and waddled away...
I DON'T KNOW HOW THEY KNOW, THEY JUST KNOW!
My favorite "cognitive CAG" story happened on Halloween. At my place, Rather than deal with the birds going off every time someone comes to the door, I put them out in my front yard in the tree, and sit outside and pass out candy...
Well, both my macaws are "lap birds." They like the tree, but they prefer the lap, so they will only stay up there for so long... so it wasn't long before I had one on my lap and one on my shoulder as I sat under the tree.
There was this little girl, who by the looks of her, couldn't have been more than 4 or 5 years old. It was her first Halloween, and she was so excited she was literally sprinting from house to house, with a bag of candy that was almost as big as she was...
So she comes running up to my house, and about half way across the lawn, she figures out that that big red bird on my lap WAS REAL!!! She attempted to put on the brakes, and immediately face planted under my tree, and began crying.
Tusk, my CAG, waddles out to the lowest branch directly above her, leans over and says: "Awww... whatsamatter? You're Okay. It's okay. Com'on. Com'ere." Now, my other birds all know the words, "Com'on. Com'ere." so when Tusk started repeating it over and over, they all did. By this point we had a crowd of about two dozen onlookers with their jaws dropped.
I made a point of holding Maggie's beak with two fingers, so she could scratch his head, and I gave her extra candy.
So, yeah. They're cognitive.
