The bird feeder

Down in early April, back up in early December. The dates follow BearWise, the bear program state wildlife agencies run: remove feeders when bears are active. They are when bears start waking and when dens are full, by Utah Wildlife Resources' den and wake months.

When bears are active, the best option is to remove bird feeders.

Bears out in winter

How easily a denned bear is roused, in the words of NJ Fish and Wildlife:

While in torpor black bears are capable of being easily awakened if disturbed and they may leave their dens on mild winter days in search of food.
