If a deer senses danger, they often run away from it. However deer, especially males will often defend their territory or harem using their horns or front legs - ever seen the funny revenge video of the deer attacking the hunter? That is a good example of the deer using its legs only to defend itself and ward off the human.
Remember deer have acute hearing, they are very cautious, weary animals and live in groups for protection, these are herbivours after all, that's why they have eyes on the side of their skull - designed to be on the lookout for danger constantly.
Ofcourse deer are also nimble, quick and agile animals, all these are adaptations and structures to help the animal when it must escape or face danger.
The walkers had wandered into the deers' feeding ground.
Some trees in the deers' forest were being cut so they moved to another part of it.
the food supply is grass and what ever else they eat because a deers usual adaptation is the grassland anyways.
Not usually. Deer is both singular (one) and plural (many). As is moose.Deers can be used as a plural form of the word deer. If there are several types of deers in the same area than you can use the plural, deers. For example, If there is a field full of mule deer then you use deer, but if there are a mix of mule deer and white tail deer, you would use deers.
