The bird feeder

Up in early January, down again in early April. Oklahoma Wildlife Conservation says to take feeders down while bears are active, in the words below. The dates are when dens are full and when bears start waking, by Oklahoma Wildlife Conservation's den and wake months.

Consider taking down backyard bird feeders for the summer and early fall, as the birds have plenty of wild food sources during those months.

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.
