I talked it over with my husband and realized why and how it can be the bird. They've met quite a few times when Crowley would get up early, Jacob (the parrot) would always talk to him (from a distance or behind glass from the enclosure). Jacob was always happy and didn't look hostile at all... Till very recently, when Crowley gets up early, I get Jacob and sit with him while my husband gets Crowley to his room so we can keep them apart. Well recently Jacob has become jealous of Crowley (he wants all the attention to himself at all times) so he's been lunging at Crowley, they were very far apart but I guess Crowley must be scared of Jacob since then.
Even if he isn't scared of Jacob I feel as though it's best to move Crowley away from him. Thank you all for your advice. I will be moving Crowley's enclosure as soon as I can, probably tomorrow.
