    you can get some impressions by going to ebird, use explore, species map, select this species and compare distribution in July and January. The northern form reaches into Chile (Putre) in the very north. Niels

    My post was aimed at describing the current situation while I feel you are talking about the ideal situation. I do not feel this thread is the right place to discuss what is ideal. Niels

    At least in August this seemed to be the typical view of this hummer - in the top of a distant tree, viewed from higher up above the top of other trees.

    Not a great picture but is this an american goshawk or coopers hawk? Washington state may 24.

    First of all, northern Goshawk is no more. It is either American or Eurasian Goshawk now. Secondly, if you are in the US for a longer period, then I would encourage you to get your hands on an older book called Hawks in Flight. Niels

    Nikon 800MM DSLR F/5.6 FLED Nikons most expensive production LENS

    For your information: when a photo exceeds a certain size (probably in mpix, and I am not sure where the cutoff it) it will only show as a link and not as the actual photo being visible. A person with a large enough bandwidth can still see it by clicking the link. Niels
