Cooper's and sharp-shinned hawks at bird feeders

When: October to March

From fall through winter, Cooper's hawks and sharp-shinned hawks hunt songbirds at backyard feeders in Massachusetts, and a feeder that suddenly empties of birds may have one nearby. Cooper's hawks are about crow-sized with a rounded tail tip; sharp-shinned hawks are about six inches smaller with a square-cornered tail.

Why this time of year

Sharp-shinned hawks, here mostly on migration and in winter, can camp at a busy feeder for the easy prey; Cooper's hawks nest in Massachusetts suburbs and hunt feeders too.

How to notice it

  1. If the feeder goes quiet all at once, scan nearby branches, fence posts and hedges for a perched hawk with a long tail and short rounded wings.
  2. Look at the tail tip: rounded suggests a Cooper's hawk, square with corners suggests a sharp-shinned hawk.
  3. If it soars overhead: a Cooper's hawk's big head sticks out well past the wings; a sharp-shinned hawk's small head barely clears them.
  4. It is natural predation. If it bothers you, Mass Audubon suggests stopping the seed for a few weeks so the hawk hunts elsewhere.

Try this with kids: All the feeder birds disappeared at once. Can you find who scared them away?
