Grackles and starlings at the feeder

Grackles, starlings and blackbirds arrive in flocks and empty open trays and big hoppers fast. Switch to feeders they find hard to use, such as a tube with short perches, a cage with 1½ in openings like the Duncraft Squirrel Proof Selective, or a suet feeder open only from below, and leave cracked corn and mixes off the trays while the flock is around.

Squirrel Shield Advantage Cage Feeder

  • Holds 3.2 qt
  • Squirrel-resistant
  • Comes apart to clean

Two defenses in one feeder where squirrels raid: a cage, and a shield that drops over the ports under a squirrel’s weight.

Keep in mind: Nature’s Way does not give the size of the cage openings, so check that the birds you want can get in.

Why they take over

Common grackles, European starlings and red-winged blackbirds feed in flocks, and a flock can clear an open tray or a large hopper in minutes and push smaller birds aside. Grackles eat almost everything offered, from sunflower and cracked corn to millet, peanuts and suet, according to Project FeederWatch, and they feed most comfortably on the ground, on platforms and at large hoppers. Grackles and blackbirds are native birds: the aim is to make the feeder harder for them, not to harm them.

Feeders that favor small birds

Project FeederWatch notes that tube feeders with short perches suit finches and small birds but exclude larger birds such as grackles and jays, and that a small hopper keeps grackles from perching comfortably. A cage does the same with a barrier: Birds Choice’s 1⅜ in openings keep grackles and starlings out. Some weight-sensitive feeders close under a heavy bird: Kingsyard’s squirrel-proof house shuts when a squirrel or a large bird lands, and Brome says that adjusting the spring on its adjustable Squirrel Busters can help, though it promises nothing against nuisance birds.

Suet without starlings

Starlings love suet. A holder that is open only underneath, such as the Birds Choice or Duncraft upside-down suet feeders, lets woodpeckers, nuthatches and chickadees cling and feed while starlings struggle; FeederWatch notes that such cages tend to be starling-resistant. A suet feeder inside a wire cage, like the Birds Choice WC13, keeps grackles out too.

Change the menu for a while

Cracked corn, millet and mixed seed scattered on trays and on the ground draw a flock fastest. While the flock is around, leave the trays empty and offer black-oil sunflower or nyjer in tubes with short perches, which small birds use and grackles find awkward. When the flock moves on, put the trays back out for doves, juncos and sparrows.
