TLDR
In this paper, computer-generated animations of raptor-shaped images were presented on an overhead video monitor to explore the stimulus characteristics necessary for eliciting both aerial alarm calls and non-vocal anti-predator behaviour (e.g. crouching and visual fixation).About:

Signalers and Receivers in Animal Communication
TL;DR: In animal communication natural selection favors callers who vocalize to affect the behavior of listeners and listeners who acquire information from vocalizations, using this information to represent their environment.

Female preference for swords in Xiphophorus helleri reflects a bias for large apparent size
TL;DR: Female preference for a sworded male was abolished by enlarging the image of a swordless male to compensate for the reduction in length caused by removing the ornament, consistent with mate choice being mediated by a general preference for large males rather than by specific characters.
Journal ArticleDOI
Can video images imitate real stimuli in animal behaviour experiments
TL;DR: The use of video images in place of natural stimuli in animal behaviour experiments is reviewed, the contribution made by video studies to date in the understanding of animal visual responses is considered, and recommendations as to the future uses of video are made.

Die hard: A blend of freezing and fleeing as a dynamic defense—implications for the control of defensive behavior
TL;DR: Freezing and fleeing constitute together a complex and flexible defensive response, and are probably controlled by different motor systems that are inter-connected to allow fast switching between these behaviors, as required for an effective and versatile response.

Looming vulnerability to threat: a cognitive paradigm for anxiety.
TL;DR: The looming vulnerability model is presented, conceptualized as an important cognitive component of threat or danger that elicits anxiety, sensitizes the individual to signs of movement and threat, biases cognitive processing, and makes the anxiety more persistent and less likely to habituate.
