Checked his portfolio... he is not even a sports, wildlife, or, especially, bird photographer!!!
Yet, he speaks with massive authority on all things. Likely, we should go to him for dating advice as well, and also information about how and when to plant our crops.
I quote Russian Proverb: Ocean is knee deep to him.
Who is this person? Someone we should quickly forget, as there is nothing memorable about him.
You are correct that he does not photograph wildlife, but he does photograph sports. He has photographed Formula 1 for some time and has had his photos of it published. He also photographed the winter Olympics in Vancouver.
Although Ron has reduced time on his blog so I suspect this is no longer true, at one time his blog was among the top ten photography sites in traffic. His photos have been published in numerous magazines and he often gives workshops. While even he will admit that there are many photographers out there more talented than he is, he certainly has more credibility than you.
