I was watching Planet Earth 2 yesterday and came across this line said by David Attenborough:
At the first sign of danger, the young ibex instinctively run back to steeper ground.
I am thinking it should be "runs" and not "run." Am I right or I am missing something?
UPDATE: The wolf was only chasing ONE Ibex, not more than one. The scene(segment on ibex) was about multiple ibex, but not that(chase) scene. That particular scene was only focused on the Fox and the young Ibex(one/singular), and so my question.
