Term for a prey animal's recognition that something potentially threatening is looking at it?
&quot;Gaze&quot; is the typical term for the direction something is looking, including head/neck and eye position. Gaze detection, gaze following, and gaze perception are used in the literature; there might be other combinations with the term &quot;gaze&quot;, as well, I see lots of results with a more general gaze+predator search.
These are all more general terms than the specific use by prey animals, particularly in social gaze: being able to figure out what others around you are looking at, but they are to some extent the same sort of ability.
