Spiritbird, I'm totally convinced that Maui is very much able to feel what I'm feeling, obviously to a certain degree. However, for example, several weeks ago, I had some personal family issues that had me feeling rather sad and weepy. As I laid on my bed with my pillows propping my head up, he climbed up on my chest, chirped to me a few times and proceeded to snuggle right in to me, ocassionly looking up at me, kissing my nose and then went back to snuggling up to me. He was trying to make me feel better and he sure did.
Ya know how your bird will fluff up around his head and beak area, making it amost seem as though he's smiling at you? You know, that "happy bird" look, that Grey's in particular can get?? This is what I get from Maui each evening just before I cover his cage, I sing to him a lullabye and then softly and gently caress his head, cheeks and under his mandible for a good while. He LOVES this so very much, but ONLY at this time each evening. If I were to attempt this during his "busy busy" time in the day, he wouldn't much hang around for it.
I honestly believe that most animals are far more in touch with the energy we/they put off than humans are. Humans are able to communicate through language, I think most animals communicate through the energy they put off. They are more in tuned with their 6th sense than we are.
