I, as a rank amatuer have tried to take pictures of hummingbirds and my results are laughable compared to these detailed images.

You should be very proud of them !

I see a lot of nice bird images but in the case and some others I have no idea where the birds are native.

In my neck of the woods ( upstate NY ) we have one type of hummingbird for part of the year and though nice enough, they don't hold a candle in one of their tiny tiny talons to this variety !
