Here you can see the typical damage of metal sucked up during the flight. Here the damage is much more critical, with pieces torn out.

When a bird hits a turbofan engine you will see that the blades are rather curved. This is because organic material is softer than the fan blades and so less critical damage will occur.

Bear in mind that a composite fan blade (eg B777) will have a different pattern of damage with bird-strike because the metallurgical structure is very different from a 'traditional' blade

the residue of feathers on this part therefore indicates that the engine first had a bird strike, as a result of which metal parts of the engine have been broken off. These eventually also hit this blade and caused the damage.
