What does she want?

hello! i feed apple slices to a wild rainbow lorikeet pair every so often (they make quite a mess as you can see) and recently the female has started to do this every time i crack my window open when they’re around. at first i thought she was asking for food, but as you can see here there is apple available! maybe today’s apple is not to her standard 😭. is she okay? is she just curious? does she want to play? i don’t want to open the window any further because i think she will come inside, which would stress us both out. thoughts?
