The accusers assert that it's a particular trained wolf named "Ossian" who is evidently known to people who know about the relatively few trained animals who are used in photo and movie shoots.

If you photograph a lot of birds, it becomes easy to recognize likely shots of captive birds. For instance, if someone has three close flight shots and two close portraits of raptors all taken on the same day, then they were probably visiting a raptor rehabilitation center or a falconry exhibition. Someone like Frans Lanting has the resources, knowledge and personality to get fairly close to birds that are hard to get close to, so if some unknown photographer has a fantastic shot that would normally require building a tall scaffold in the rainforest, then it tends to raise questions.
