These are the greetings we get by Joey and Petey (each saying the one with their respective names).
But there might be a new bird in the mix saying these things.
The Boy had mentioned in the past that Pixel had started staying "Hey Joey" (she's also nicked his low toned "hello" and makes it very confusing as to know who's saying it when..). He was surprised that she hadn't picked "Hi Petey" yet as Petey does repeat that one very often.
Well this morning she said it - a rather clear "Hi Petey" although not exactly said in the same way Petey will say it.
It was cute!
