field guide modifications

So, do I know a lot about Northern Goshawks? I personally know little about Goshawks. But there is nobody who knows more of Goshawk habitat, migration, and distribution than what I know. All field guides need to be modified to show the true habitat, migration , and distribution of Goshawks. Very few field guides will state "Goshawks are a common species in many areas of the United States". Those same field guides then will state that the raptors are elusive. Again, my mantra, Goshawks can be an elusive species - but not in the sky. This is why birders should meet the challenge and become hawk-watchers. My other mantra - I beg for you to understand what hawk-watching is all about!
