We are privileged to have a birds-eye view (literally) of magpies that are building/renovating their nest, right outside our bedroom window. They are very shy birds that don't really like human company, so my filming was done from indoors. Somehow, they seem to discover that they are being filmed, but I have managed to get some footage of them. Once they find out they're being filmed, they go into their nest or fly away. They are very protective and territorial concerning their nest; we think the same magpie couple has come back each year for the past few years to raise another family. Since last year, we've had some intense storms with high winds, which damaged the nest considerably. So they've been working hard to repair and renovate it.
Here is some video footage I got this morning:
