Police around the Twin Tiers are reporting an increase in car-deer crashes in recent days.

The number of collisions between vehicles and deer rises at this time of year.

According to the New York State Department of Motor Vehicles, two-thirds of the reported crashes with deer happen during the months of October, November and December.

Authorities say deer activity is highest at dawn and dusk. They say drivers should be especially cautious when passing through rural, wooded areas.

Police also note that deer travel together, so motorists who spot one should expect others are nearby.

Officials say about 65,000 car-deer collisions are reported annually in New York State. The state's deer population now is estimated to be around 900,000.
