I doubt it but maybe your bear had a bad experience with a skunk so your
bear gives skunks the right of way. I have seen farm animals and dogs which
have been sprayed by a skunk never go around a skunk again.

We had a orphaned skunk which we had the scent gland removed as a pet on the
farm. The skunk loved attention and people. When salesmen would come to the
farmhouse we would let the skunk out the front door (when he was young) and
he would run to greet the salesman. We laughed till we had tears in our eyes
until Grandma made us stop. When the skunk got older he lived outside with
the farm dogs and never left the yard. The skunk died of old age at around
six years of age.

Could a descented bear skunk kept in our remote apiaries in bear country be
the answer to our bear problems?
