Black Creek Park • December 1

Northern Shrike. These birds nest up in Alaska and upper Canada. They spend the winter in the upper United States. Their southern region cutoff during winter is usually the New York - Pennsylvania border, though at least one has been reported in New Jersey this year in November.

Northern Shrike. These birds are about the same size as a mockingbird. In fact, a mockingbird regularly shares the same bushes at this shrike. I would think that unwise, as shrikes will take birds as big as robins, according to Cornell’s Birds of North America.

Northern Shrike. Their scientific name, Lanius excubitor, means “butcher watchman,” an indication of its excellent predator abilities!
