That video (linked by everdev) makes it look like the bird was more damaging to the plane than the same-sized drone was (it tore a bigger hole). But the tester says the drone strike was more of a problem because it penetrated the wing and damaged internal structures (hydraulics? electronics? fuel lines? Structural components holding the whole wing together?), and that for safety, drones should be made more like birds. My understanding is that planes mostly continue to fly even if you change the shape of the wing (see all the examples of planes flying upside down or with one wing). Probably the answer is "it depends", especially if we are talking about a flock of birds compared to a single drone.
