Really amazing captures from everyone. I particularly enjoyed Kerry B's series of exotic species (to me), dpc's raven and geese, CTJohns' spoonbills, gary samples' owl, serendipidy's night heron (Harry?)...just to name a few.
Below is one of the first images I got out of my brandnew Tamron zoom on my first day of trials -- that is to say, this morning. It was overcast but thankfully no rain. I shot everything handheld (tripod too clunky, no monopod yet). The 150-600mm definitely felt heavier than my 70-200mm!
