Scavengers can be picky eaters

Vertebrate scavengers prefer to dine on the carcasses of herbivores like mallard ducks and chickens, rather than higher-trophic-level vulture remains. This study found that avian and mammal scavengers only consumed a small portion of the vulture carcasses, highlighting the complexity of nutrient cycling through food webs.
