State transportation crews have picked up 4,249 dead deer from state roads and interstate highways this year as of Oct. 31.
It's a common sight in New Jersey this time of year: dead deer, usually on the shoulder or the median, victims of collisions with vehicles.
While the state cautions motorists every fall to be vigilant as mating season begins - sending deer literally leaping across roads - the animals have another thing on their minds.
"They're not really slowing down or cautioning themselves," said Dan Roberts, acting deer project leader for the New Jersey Division of Fish & Wildlife. "They're focused on the mating season."
Roberts said Thursday that New Jersey is currently at the height of the mating season, or the rut, so deer might appear out of nowhere, and sometimes into the path of motorists.
One deer hunting prediction website charts today, Nov. 13, as the average peak of white-tail deer mating season in the country. Whether it's today or tomorrow, "The peak period is right now," Roberts said.
The total number of deer killed on New Jersey roads every year is estimated and usually clocks in around 25,000. And they have to be removed.
The state Department of Transportation (DOT) records every deer carcass they remove from state roads and interstate highways.
In all, DOT work crews have picked up 4,249 dead deer this year as of Oct. 31, which is behind last year's pace.
As of Oct. 31, 2014, the DOT had logged 5,061 carcasses and by year's end 2014 they tallied 6,993.
So far this year, Monmouth County is leading the way with 642 as of Oct. 31.
Hunterdon County is close behind, with 613 carcasses. Somerset County ranks third with 558.
The numbers do not include county and local roads, as counties and municipalities are responsible for those removals, the DOT says.
But the numbers show how varied the deer hits are across New Jersey.
In urban Hudson County this year, DOT work crews have picked up just one dead deer. For all of last year, also just one deer body in Hudson.
In Cape May County, crews picked up just 10 deer in 2014 and this year just three as of Oct. 31.

In the past four fiscal years, the state has removed an average of 6,300 deer carcasses from roads they maintain, said DOT spokesman Steve Schapiro.
While the state picks up over 6,000 a year, estimates on how many deer actually meet their end with a bumper or the undercarriage of a vehicle varies.
Roberts, from the Fish & Wildlife division, said State Farm insurance company studies deer hits annually their latest estimate for New Jersey's car versus deer strikes at 25,976.
Roberts said the state believes the estimate is conservative, and could be as high as 50,000, due to some vehicle owners taking care of repairs on their own due to high insurance deductibles, or motorists not reporting the hits at all.
"The numbers are fairly astonishing, with the amount of people and roadways we have in New Jersey," Roberts said.
The deer population in New Jersey is estimated anywhere from 110,000 to 200,000. Roberts said.
Schapiro, from the DOT, said the state makes every effort to respond within 48 to 72 hours to remove reported dead deer.
"We do our best to maintain the safety and beauty of our state highways but we also rely on help from the general motoring public to alert us directly to locations where they see dead deer, trash, potholes, or other maintenance issues," Schapiro said.
Motorists can report dead deer locations to the state on the NJDOT website.
