short whimpers throughout the night

this is a bird we adopted from my mom the bird is 27 years old and has really bonded with my wife and i. we also have a shitzu and black lab .

now and then the bird will try to challenge the shitzu but is not bothered by the lab at all .we also nonoticed his beak on the bottom is deformed or not lined up , does he need it clipped.the bird is very happy with his large cage and eats well he likes brocolli carrots cheese crisps and peeled grapes.

getting back to our main question ...is the whimpering something tell tale or does he need to be covered at night .he appears to be happy with us but he shares attention with the dogs . any comments appreciated. thanks bob
