Antler tags to stop reindeer getting hit by cars
The other reindeer might have laughed at Rudolph's bright red nose, but it seems he's having the last laugh as thousands of reindeer in Norway have been fitted with reflectors to make them more visible.
Around 500 reindeer are killed each year and a number of motorists injured in collisions with the animals on Norway's frozen roads. Officials hope the reflective collars and antler tags will cut that number down.
The leader of the project at the Norwegian Public Roads Administration, Kristian Oevernes, said: "This is the first time it has happened on this scale, [but] it really works."
Tests have already shown the reindeer to be more visible with the latest tags – other measures have been tried before, such as reflective tape where the glue failed because of the cold, and fluorescent spray which affected the reindeer's fur coats.
There are around 200,000 reindeer in Norway, so getting to them all might prove tricky, but officials remain hopeful they can prevent further serious accidents.
