Rob writes: "These are not very sharp photos, but they demonstrate how a trail camera can capture wildlife events for us to see and understand, that we would struggle to witness with the naked eye. The sequence clearly shows the avian hierarchy from beginning to end. It is sickening to see, but educational too."
Nature is not always gentle. Sparrowhawks are specialist bird-hunters - they are exactly why smaller birds flock, alarm-call and stay close to cover. And Crows sit above Sparrowhawks in the pecking order: big, bold and never shy of stealing a meal. Without a trail camera quietly watching an ordinary corner of a garden at 6am, none of this would have been seen.
