Displaying Common Crossbill

I came across a small group of Common Crossbill locally today feeding in larches with a large group of Siskin. Several of the males were in song and one male gave a brief display flight with wings held open whilst it glided giving a typical, repeated 'glip' call.
Common Crossbill is a sporadic breeding bird in the area and they are very early nesters and could be feeding young already!
