I think that this is hugely important not only because it reinforces my eternal mantra of a strict solar schedule but also because I've read so many times about owners that leave a light on for their birds at night so they 'won't be scared'. Now, don't misunderstand me, I realize that they do it thinking they are doing the bird a kindness but, in reality, they are not. Babies and very young children might benefit from this practice but not birds.
