I don't imagine the birds will last long. They weren't living there before, for some good reason. They've been displaced from the island, they've moved into an area that's not so good for them, and their numbers, I'm sure, will dwindle in no time.
Yeah, I have pretty much the same hours as you, but you're on the other side of the planet. I would have a life, but while most people are out living I'm at work.
