all this bird strike talk has me wanting to get a bucket of greasy kfc chicken........

has there been any solid speculation as to a bird strike with the crashed b-2 ?? if so, can't ornithologists help prevent strikes?? remember the hitchcock movie "the birds"??

No solid speculation, only a wild guess - just one of MANY possibilities. It's just extremely unusual for 4 engine airplanes to crash for any reason.
The Air Force does have a bird risk mitigation program, but it mainly revolves around pireps of bird reports and avoiding takeoff's and landings during periods of increased activity, such as during migration periods, and avoiding flying low over water sources. Birds can't be avoided entirely, but you can lessen your chances of a strike considerably by flying smarter. There have been lots of experiments with trying to scare birds away from everything including scarecrows, releasing natural predators such as falcons and hawks, noise guns and various other methods. All of them involve some amounts of success, but I don't think any method has been 100% successful.
Birds are one of the largest threats out there to jet aircraft! This is especially true for airplanes that fly fast and fly low, such as air-to-ground fighters and bombers.
