They usually are friendly, but be very careful as they can be startled easily. A giraffe will defend itself from humans if it feels threatened.
Giraffes are social animals. Female giraffes associate in groups called herds, occasionally including a few younger males. Máture males live in "bachelor" herds and fight for dominance using their necks. older males are usually solitary.
For the most part giraffes aren’t territorial. Males will become that way when they want to mate in order to keep other males away from the females they plan to court and then to mate with. They can become more territorial though when there is less food and they have to fight to keep their herds together.
