Hi everyone,
  After experiencing the great owl irruption a few years back, and then seeing all of the Northern Hawk Owls this winter, I was wondering what the difference is in the diet of great grays versus hawk owls? And if there is not much difference, why the current irruption of only hawk owls? Thanks in advance for anyone knowledgeable and willing to share!
