Owl baiting has had a lot of discussion. Minnesota was considering a ban on baiting a few years ago, but then people pointed out that baiting was allowed for bear hunting, and there was no specific research at all on the topic. The effort died.This is one of those debates that nobody's going to agree on I think. What's acceptable to one person isn't necessarily the same as what's acceptable to another person. Just like feeding them…a lot of folks say absolutely not but putting out a feeder for hummingbirds is fine…so it's just a matter of degree that an individual is willing to accept. There really isn't any right answer to the question…a lot of folks like Brad Hill say that if the animal/bird looks at you and does *anything* that isn't completely natural then you're interfering with the shot. That seems a little overkill to me…but as I said it's an individual thing. In a lot of places…the wildlife is perfectly habituated to people and just doesn't care…alligators in Florida and birds in the Everglades for example, elk and bison out west.
I can kinda/sorta get the feeding thing if you're feeding them pet store mice that might be infected with something…whereas feeding them wildlife feeding quality mice won't be…but then you could be accused of still 'baiting them'…but if you put the mice out in the field where there are probably mice anyway but one happens to be out in front of your blind or in the sun or whatever are you really baiting them? Depends on the shooter…
This is one of those debates that I tend to not express an opinion on outside of "everybody is different".
There is a concern about bait that is not natural or native. There is also a concern about bait that changes behavior. Many of the raptor deaths are because raptors are feeding on rodents attracted to the roadside for food thrown out a car window. There is a legitimate concern over baiting any raptor, and it is considered by Audubon to be unethical.
There is a difference between legal and ethical. NANPA adopted a policy through its Truth in Captioning guidelines that provided several different levels of disclosure.
Here is a good article about the topic.

Keep in mind that part of what drives a lot of this is the commercial demand. Jim Zuckerman made a Facebook post today with a photo of a wolf. He's teaching a workshop, and people taking the workshop want to photograph wolves. You might not see a wolf over several days in Yellowstone, but at Triple D Game Farm there are captive wolves that have been trained to follow commands. Some people are against game farms, but might support other types of zoos. If you want to have a photo of a wolf for a publication, it's usually a stock image from someplace like Triple D. But some publications now refuse photos of captive subjects. It's complicated.
