Do lovebirds need light

They get spooked very easily at night, so its good to leave a night light on for them.

Actually, cockatiels are not scared of the dark, and they do not get spooked at night time, unless people insist on creeping up quietly and looking at them, disturbing them suddenly. Cockatiels and other parrots should not have a night light as it disturbs their natural day-night rhythm. They should be covered at night, with the light out, and no other pets to disturb them.
