Cover, what cover?

We cover the birds' cages at night. We have always done so and it's something we'll keep doing. However, the last two days, this is what greeted us, in a way, when we've entered the bird room in the morning.

Yes, Léa has started to uncover her cage on her own. She's not being noisy once uncovered, but there is no denying she's looking proud when we look at her. Wonder if this will be only a week-end thing (as they don't get to come out as early), or if the same sight will greet us tomorrow morning...
