As Ethopian Christians give up meat and dairy for Lent, hyenas are forced to switch from scavenging to hunting, a new study has found.
Humans aren't the only ones who give up certain foods for Lent. In the 55 days before Easter in Ethiopia, hyenas are forced to turn from scavenging to hunting to make up for Christians' fasting traditions.
Members of the Orthodox Tewahedo Church give up meat and dairy during the Lent period in Ethiopia. Now, a new study of hyena droppings finds that local hyenas, deprived of butcher scraps during this time period, supplement their diets by hunting donkeys for food instead.
Spotted hyenas are adept hunters, capable of bringing down prey such as zebras, wildebeests and even young rhinoceroses. But these pack hunters are also adaptable: They scavenge freely, devouring everything from dead birds and mammals to garbage and dung.
"Hyenas can eat almost any organic matter, even putrid carrion and anthrax-infected carcasses," study researcher Gidey Yirga of Mekelle University in Ethiopia said in a statement. "They are capable of eating and digesting all parts of their prey except hair and hooves. Bones are digested so completely that only the inorganic components are excreted in the hyena's droppings."
Knowing that hyenas scavenge from human garbage, Yirga and his colleagues investigated whether human diet changes influence what hyenas eat. They focused on Lent, collecting hyena droppings from three sites in Northern Ethiopia on the first and last days of Abye Tsome, or Lent, and then again 55 days after the fast ended. The result was a collection of 553 individual droppings.
