Greg,
The first thing I would reccomend is to do a little research on your intended "pray". Try to find out what it would eat in the wild,how it would aqurire it,ect. If it is a Bald Eagle it is a fisher and scavanger. So if it happens to find something to eat near your blind (something it would naturally eat) and you happen to capture a great image; what harm is in that?
Then you could share that image with others and get them interested in this magnificent animal.Get them to understand it's needs (as habbitat, privacy) and hopefully in some way you will help this species flurish long into the future; what harm is in that?
Good luck & good shooting
