If you observe the photos of the incident, you will find that the dent was in the radar dome in the nose, which is not nearly as strong as the windshield. Doesn't need to be, it isn't part of the pressurized section. Note also that the dome was not punctured, so whatever hit it was fairly blunt, like a large bird. The absence of blood on the dome is a bit curious, though... maybe the photo just doesn't show it.
Note also that the radar dome didn't fracture apart, it just buckled but remained intact and remained in position. It did what it was designed to do - take an unexpected hit and not shatter or dislodge and possibly FOD the engines.
Modern airliners have been tested extensively for bird strikes, especially on the windshield, as a breakage or intrusion at speed there could be catastrophic to the aircraft, as in rendering the pilots blind or unconscious.
This isn't a very serious incident. The radar dome was buckled, but that's about all that happened. Radar domes on airliners have suffered similar damage in flight from large hailstones, without seriously impacting the aircraft's ability to fly.
As it is, the flight crew responded exactly as they should have, and the flight landed without further problems. Had the bird hit the angled and much stronger windshield, and not the blunt, forward facing radar dome, it would most likely have just glanced off, maybe leaving a nasty blood smear.
