I just received the latest issue of National Geographic the day before yesterday (January, 07 issue) and there is a beautiful article about Hummingbirds. I was quite impressed to say the least.
Then, in the back of the magazine, it shows/describes how the photographer actually catches his specimens, places them in his SUV mobile studio next to his waiting nectar-bearing blossom, and releases the hummingbird when he is ready for the shot.
It's one thing to shoot birds near feeders, but to actually capture them?! I suppose it depends on what you're trying to accomplish with the images. And he was hired by N.G. so that makes him a PRO.
Definitely straddling the boundary in my book. At least use zoo specimens which are already accustomed to being handled.
What do you think? Am I being too sensitive/idealistic?
