Fawning season traditionally begins during the last week of May, peaks in the first couple of weeks of June, before gradually tapering off. And that means deer are on the move.
Does are secretive about the birthing process and will venture out from normal use areas looking for a secluded spot to deliver this year’s crop of fawns in peace, said Jim Coffey, forest wildlife research biologist with the Iowa Department of Natural Resources (DNR). “This seclusion process is a driving force in protection for the lanky, wavering fawn. Fawns will be left alone while the doe returns only to nurse. This is normal deer behavior,” he said.
“The doe searches out an isolated location where she feels safe and, on occasion, those places may leave us scratching our heads wondering what the doe was thinking. But she chose that location because it made sense to her,” Coffey said. “The worst thing someone can do at this stage is to ‘rescue’ the fawn. Mom is likely nearby and watching you. Leave it be, or if you did handle the fawn, return it to where you found it and walk away.”
With the recent flooding and saturated soils, many areas near river bottoms are not available for fawning, pushing deer to higher elevations. These spots can be anything from open hayfield to a field terrace to the flowerbed in the backyard.
The Iowa DNR will not be rehabilitating or comingling fawns with other deer to avoid the potential of spreading chronic wasting disease – or other disease - to new areas. This emphasizes the point of leaving ‘abandoned” fawns be.
The spindly legged newborn fawn is designed with a few survival tools built in –its spots are cryptic camouflage that emulates the sunlight spots projected onto leaf litter of the forest floor and its lack of movement the first two weeks helps to reduce scent patterns. This combination is its best chance at survival until it is capable to following the doe.
Fawning season also coincides with an increase in deer vehicle collisions.
“There is a lot of movement this time of year that relates to the social structure of deer. The doe is on the move looking for the safe isolated place to have the fawns. Additional movement comes from last year’s fawns that are now isolated teenagers starting to venture out to find new space. These yearlings have to make their own decisions for the first time, encounter other adult deer and build new social structures,” Coffey said. “This movement behavior can occur during all times of the day. Once it settles out, the active movement time will return to dawn and dusk.
“The key to remember is that for the next month deer may not be acting like we think deer should act, stay alert while driving at any time of the day.”
Drivers are reminded to drive defensively, avoid distractions, slow down, and provide safe distance between vehicles. Don’t veer for deer. If a driver does hit a deer, drivers can get a salvage tag for the meat by calling either the local conservation officer or local law enforcement agency. The salvage tag is free and is required to legally possess the meat. Salvaging requires that the entire deer be removed from the roadway.
