Woodpigeons mobbing magpies & Long-tailed tit back!

The magpies are still building their nest in the monkey puzzle tree opposite, however I noticed that the woodpigeons are mobbing the magpies, anyone else seen this behaviour?

  6. Long-tailed tit x 1
  7. Magpie x 2
  8. Woodpigeon x 3 – I noticed one of these was mobbing the magpies as they were making their nest. Anyone know if this is normal? I’ve seen it in song birds before but not woodpigeons.
