I love watching my birds different personalities show with things that are so simple. For example playing with a laser pointer, you shine it and they go after it right? Nope!
James will go after the dot chirping and dancing at it
Jesse will start yelling at James, he either thinks it's dangerous or know its just a dot and thinks james is dumb (he likes to lecture James a lot)
Loki will just attack the laser pointer itself, the little smarty pants knows where the dot is coming from.
Also I can add playing fetch to the list of loki's tricks. It took some doing but he responds to go get it and bring it back, and of course the treats involved. One day I'm hoping that I won't have to use verbal cues just like his other tricks where he looks at my hands.
