A behavioural adaptation of the moose is that it will instinctively tilt its head back when running through dense vegetation. By doing this, the moose flattens its antlers so that they are closer to horizontal with the ground rather than sticking straight up. The moose does this in order to stop its large antlers from catching on bushes and trees and being damaged, especially in spring, when a moose’s antlers are still growing and are soft and tender. This also makes the moose more aerodynamic, allowing them to run faster to escape predators.
The moose would most likely have developed this adaptation due to the dense vegetation of the forests it lives in and the need to escape from faster predators like wolves who do not have to carry heavy antlers. Moose often have to travel through areas of thick vegetation and a moose’s antlers must have constantly been snagging on low-lying branches and bushes before this adaptation.
