On a cold and blustery day, APHIS wildlife disease biologist Jared Hedelius sits in his truck by the Bighorn River in Montana and waits. Although the temperatures outside are well below freezing, the mallards on the river are busy searching for food, oblivious to Jared’s swim-in live trap just a few feet from the shoreline. Soon, enough ducks have entered the trap and Jared leaves his warm truck and heads to the water. He sets up his equipment and begins collecting samples.
