The blows with head and neck that especially the younger bull giraffe deliver are quite vigorous. These movements resemble that of a fight, but apparently* can be regarded as play fighting, because the blows are not as powerful and as fast as in a fight. You see both ‘fighters’ lean against each other with their hindquarters to increase stability at some moments.* Behavioural inventory of the giraffe (Giraffa camelopardalis) by Peter Seeber, Isabelle Ciofolo and André Ganswindt, 2012.
