We've had some very tame magpies visiting us for over a year, and now they've decided to build a nest in our yard, half way out on a palm tree frond, overhanging the pool, of all places.

Do I need to start wearing a motorcycle helmet? Will they still be friendly once they lay and have chicks?

I'm not sure if they'll even get that far because the branches swing around a lot in the wind. I think this frond has quite a few months left in it.
