I can assure you that it is impossible for one bird to be ingested in both engines for a couple of reasons. After going through the first engine, how much of the bird would realistically remain? How would it get back to the front of the airplane to be hit a second time? Minus wings, it would immediately start to fall. At altitude a descending 360° turn would be required (not SOP) to reintercept the falling bird a second time on the way down and some considerable bad luck would be needed to hit again with the other engine, but hitting the same bird twice on rotation? I honestly don't think it's very likely.
What you really should worry about is
two birds - with one going into
each engine.
