I saw him at Osprey Heaven the last time I was there, I go to a nesting island for Rosseta Spoonbill and others (about 6 different species) and use the same boat ramp as he does. He uses a pontoon boat and it's much more stable than my Airboat but I can get up close and personal.Mark is a great guy, very friendly in person. You should get some great shots of Osprey. I like the narration in his videos. I was planning to do one of his workshops last year before COVID messed everything up so I don‘t know how they are. I might try to get to one this winter.
