Observed evidence of predator activity, I believe a hawk has attacked a pigeon leaving no trace of flesh just feathers.
No interactions present.
The photo shows a number of flight feathers which appear to have been bitten off - see the blunt ends. This is indicative of a mammalian predator. A raptor usually strips off most if not all feathers, by plucking.
