Weird signs of a luntino lovebird

I have a 1 year old lutino lovebird that I got last Nov. When we first got her she learned to 'step up' and come to me very easily. Ever since I had to leave her for 2 weeks almost a month ago she has been showing weird signs that I'm not used to:

- Bobbing her head a lot and making a panting noise. To me it seems like she is just excited.

- Her feathers are always fluffed up and she preens a lot.

- Just today I put some paper in her cage and the next thing I know she is opening her beak really wide and staring at it. (Is she just happy to have something to shredded)

-She also no longer stays by us long when she is out of the cage and doesn't step up easily, so it is harder to put her back.

- Last thing, she sleeps a lot when we aren't playing with her. Should I try a new toy to keep her active.

Anything that you could tell me would be great. She is my first real pet on my own and I love her tons.
