A plane that took off from LGA yesterday had a bird strike which took out one of its engine and prior to that there was another bird strike incident with an incoming plane. Are these bird strikes happening more often or are they just be reported more frequently in the media? Are these bird strikes very problematic at other major airports besides LGA?

Bird strikes are very common, taking out engines is not.

They're especially common at LaGuardia, because there's some kind of sanctuary or body of water nearby, where they congregate. Compared to other airports, like Seattle, San Francisco, LA, etc., which are surrounded by salt water, vs. the fresh water near LaGuardia. There's some debate, however, re: whether removing geese from the LaGuardia/JFK environment would mitigate the problem, as those airports happen to be on a major Canada goose migration route. They can reduce the population of resident geese, but migrating geese from Canada fly through there seasonally.

Engine safety tests used to be done with frozen chickens or turkeys, to determine if the engines could handle it. The tests proved inadequate, after the Hudson River incident, when birds much larger than the test material were involved, plus a large flock of them hitting the engines all at once is much different than the test conditions. So now they've modified the tests to more closely reflect reality.

^^ The birds were not frozen. The company I worked for used to perform this test.

This is a bird strike test on a Rolls Royce.

This second video is NOT a bird strike test as it's labeled on youtube, but a blade shear test.
