Answer:
At night, dusk and dawn is the most probably time to look out for animals
Step-by-step explanation:
Intersections: at road intersections you should be looking out for vehicles or humans crossing to avoid collisions
railroads: you should be looking out for oncoming trains to avoid collisions as well
Night, dusk and dawn: a lot happen at this times because visibility is extremely poor at this times and animals tend to move around by this times unnoticed so you should be more careful at this times and lookout for both human and animals
2:00 pm : this is in the thick of the day and you don't have to lookout for animals by this time
