THE PIONEERS USED TO RIDE THESE BABIES FOR MILES
Assuming GLaDOS and Wheatley are terrified of birds just because they were startled by them a few times. I can understand giving them that fear based on those encounters, but playing it up as them just screaming “BIRD BIRD BIRD” every single time they see one is just ridiculous. Play it like a real fear/phobia.
Like when your character is confused, and your partner feels the need to explain to the mod OOC. If I don’t get it OOC, I’ll say so!
