Offal Wildlife Watching: Who Eats your Guts?
Project Summary
The purpose of this research is to better understand what and when species use deer gut (offal) piles provided by hunters across Minnesota. Minnesota offers a unique opportunity to look at this across four different biomes and a large metro area. These areas have differing topography, vegetation, and human land use.

Project Description
We asked deer hunters in Minnesota to place remote cameras on gut piles from freshly field dressed deer. Volunteers left their cameras to capture pictures of all the scavenger species that used the gut pile. The purpose of this research is to better understand what and when species use deer gut piles provided by hunters across Minnesota. Minnesota offers a unique opportunity to look at this across four different biomes and a large metro area. These areas have differing topography, vegetation, and human land use. All of these things are likely to influence the different scavenger assemblages found in each area. A large amount of carrion available to scavengers is provided by apex predators or the natural death of prey. Likewise, at certain times of the year, hunters can provide a significant source of carrion in the form of gut piles. The resource pulse of gut piles that hunters provide generally occurs over a short period of time. This pulse represents a large input of gut piles into the ecosystem from animals that would otherwise not be available to scavengers. Carrion pulses have the potential to reduce predation on prey by providing a less risky meal for predators. Alternatively, predators that consume carrion may also increase predation pressure on prey populations in the same environment when the carrion pulse is depleted. Since gut piles are provided by human hunters, the suite of scavengers and time that animals scavenge is likely to differ from other carrion.
