A/c hit birds on just about any leading surface from nose to tail, wingtip to wingtip. Engine bird ingestion is only one of a number of strike scenarios, though clearly a bigger hazard.
I've a suspicion you are thinking that engines suck birds in which is not the case. If I've misunderstood please correct me.
I'm sure you know this site but I've put the link up for anyone interested.
