Smokey the bird, and Noel the bird.

Smokey the bird with her foraging toy.

Smokey is such a smart bird.  Last month, the vet suggested I buy her a foraging toy to keep her occupied and help her stop egg laying.  I told him she already had loads of toys, but he said a foraging toy will take her a long time to figure out, and will keep her from being bored.  I bought one, and Smokey immediately figured it out, lol.  In fact, she can get the treats out faster than I can put them in.
Each pie shaped compartment has one opening, and they all have to be lined up in order to get treats in, or out.   After the food is dropped into the top pie, all of the pies are twisted and turned so the holes no longer line up.  In theory, it should take Smokey quite awhile to turn them again so the holes line up, allowing the food to drop from the top compartment to the bottom.  Yah right, lol.  She twists them and is eating before I can close the cage door, lol.  Here she is, looking very proud of herself.

Smokey the bird.

Here's Noel, the bird, Smokey's friend, watching Smokey play with her new toy.

Noel has new toys too, but he'd rather watch Smokey play with hers, lol.  Smokey taught Noel to talk, and this is what I hear very day:  "Are you a bird?"  "No, you're the bird!"  "You're the bird!"  "I'm Smokey the bird!  Noel, are you a bird?"...and on and on, lol.
Then Smokey will yell, "Kathy, Kathy!  Are you a bird!"  After all of these years, she knows what I'll say.  "I'm a human being. You're the bird."  Smokey says, "Are you a dog?"  I tell her no.  She cracks up laughing, then asks, "ARe you a pretty, pretty girl?"  I tell her thank you, and reassure her that she's the pretty girl, lol.  Sometimes she barks, and I tell her she's not a dog, she's a bird.  Then she quacks, meows, etc.  She's a cool bird. 
Noel's vocab isn't as big as Smokey's, but he can say "Hi, hello, thank you, are you a bird, you're the bird".
Smokey's vocab is about the same as a 4 or 5 year old child's.
