Australian scavengers select specific parts of carcasses based on nutritional needs
Scientists in Australia published new research showing that dingoes, wedge-tailed eagles and red foxes choose specific parts of a dead animal to eat first.
New study challenges scavenger myths
Researchers found that these animals do not simply eat whatever is available. Instead, they approach a carcass like a buffet and select specific sections. This behavior contradicts the common belief that scavengers are unfussy scroungers who consume everything equally.
Nutritional targets drive feeding choices
The study suggests that carnivores choose foods to meet specific nutritional targets similar to herbivores. Different parts of the carcass contain varying amounts of carbohydrates, lipids and protein. Animals eat the section that best matches their current dietary requirements.
Data gaps hindered previous research
Scientists previously lacked data on carnivore feeding choices due to logistical challenges in tracking them. Tracking these elusive animals with large home ranges proved difficult for researchers. Scavengers now offer a model for examining how wild carnivores decide what to eat.
