Which behavior reflects poor early training in birds of prey?

Snatching food from the fist is a behavior that reflects poor early training in birds of prey because it indicates a lack of impulse control and respect for the falconer. Proper training involves teaching the bird to wait patiently for food and to take it gently when offered. If a bird consistently snatches food, it shows that it hasn't learned to associate the falconer's presence as a signal for safe or appropriate feeding behavior. This can lead to difficulties in handling the bird during training and hunting, creating a less cooperative and more challenging relationship.

In contrast, the other behaviors listed can have different explanations related to the instinctive behaviors of hawks and falcons. Binding after hitting quarry, for instance, indicates a natural predatory response and a drive to secure its catch, which is desirable. Crabbing after a hunt can signify the bird's excitement or the desire to communicate, while throwing up after meals (regurgitation) is a natural way for raptors to rid themselves of indigestible parts of their food rather than a sign of poor training. These behaviors can often be addressed through proper handling and training techniques.
