Deer rutting may not be a common term to all, but it is important to understand this time of year.

Rutting is a behavioral pattern of deer, in which male deer — bucks — chase does. It is triggered by autumn’s decreasing daylight, which causes an increase in hormones for both bucks and does. The season begins in October and ends in early winter.

According to DMV data compiled by AAA Northeast, 2022’s mating season accounted for nearly 37,000 car crashes in New York state, where an “animal’s actions” was listed as a contributing factor — most of which involved deer. Additionally in 2022, Suffolk County ranked sixth among the state’s 62 counties with the most animal-related crashes, at 1,216. Deer-related crashes in Suffolk can see a significant increase this time of year, often cited as between 50% and 75% higher than other months. Most accidents have been found to occur during afternoon rush hour, as well as dusk.

With over 30,000 deer in Suffolk County alone, North Shore residents are advised to stay especially vigilant when driving down major roadways, such as Route 347, as deer frequently dart out into oncoming traffic.

The NYS Department of Transportation urges drivers to brake firmly, but not swerve if a deer runs in front of your vehicle. Swerving can cause a vehicle-to-vehicle collision, or cause the vehicle to strike a pedestrian or fixed object, such as a tree or utility pole — which reinforces the need for reduced speeds this time of year. Additionally, it is crucial to not approach a wounded deer as it may be frightened and potentially dangerous.

Alert 911 if a deer crossing creates a roadblock, as it can become a serious threat to oncoming traffic.

Ironically, with the increased creation of edge habitats, or transition zones between forest and open areas, deer have been provided with abundant food and shelter, dramatically increasing their Suffolk population, as a result. This is among a host of factors which has driven the North Shore’s deer population in recent years, including reduced hunting.

“We don’t have a natural predator for deer, so their numbers are increasing with no control,” Isabel Fernandes, of Sweetbriar Nature Center in Smithtown, said back in 2019. “Also, various towns and communities aren’t allowing hunting.” 

In recent years, the villages of Port Jefferson and Belle Terre are two local governments that have considered amping up culling efforts, to reduce deer’s impact on our ecosystem and traffic.
