Friends, these images illustrate differences in individual Northern Goshawks.  Both birds are first year hatch birds, both males but the white content varies from white in the right hand bird to a cream color in the left hand image.  Both images were balanced with the white in the bird  and the backgrounds are very different, but i think the differences in color is apparent.  The educators at Hawk Ridge are very knowledgeable and they run a very good adoption program.  If you wish you may adopt a goshawk or any other raptor listed on their site, thereby supporting their efforts to learn more about our hawks and other raptors.  Their link is Hawk Ridge.  til Tomorrow MJ
