Mother kangaroos at higher health risk

A new University of Melbourne study reveals that mother Eastern Grey Kangaroos double their food intake and significantly reduce resting time to meet the nutritional needs of their baby. This altered behavior increases their risk of parasite infection, which may be a significant additional cost for reproducing females.
