Re-Cycled

I have been keeping an eye on this massive but somewhat messy nest that has been visible in a tree outside the Condo since last autumn, wondering who had lived there last summer. There are lots of black-billed magpies around here (USA magpies are like European magpies, not like NZ ones which are actually a crow). Also last year several fledglings around, but with thick leaves on the tree I never even realised there was a nest there.
Today, all was revealed, a pair of them were in and out, showing a lot of interest.
I will keep a watch, easy to photograph from the upstairs balcony of our building. (Just have to be there at the right time(s)).
