Night fright: (noun) Used typically in conjunction with cockatiels and horror movies. Cockatiels do not see well in the dark, so when they are startled they thrash around wildly in their cages in fright. Cockatiels can easily injure themselves during a night fright so it is important to turn on the lights and calm them down as quickly as possible. A nightlight by the cockatiel’s cage helps prevent night flights, along with only partially covering the cage. This can occur in other parrots as well.
