Was just caught by the byplay outside my window. A pair of magpies started building a nest when a larger grey crow flew in to try to occupy the spot.
There have been a few minutes of manoeuvring and attempts on each side to get the other to leave, with one using size, the others numbers. A quiet confrontation. I figured that birds getting frisky is a sure sign of Spring :)
The cosmic ballet continues.
