The classic stance of a Male Blackbird

We have 4 pairs of Blackbirds calling at our feeders in the garden so the Blackbird population must be doing well locally?
They all eat some but also carry a lot away to the their nests,so they must have young?
Great to see the songbirds doing so well.The Dawn chorus I awake to in the Morning is real nature at work!
It never ceases to amaze me!
