No one likes a bully and no bird is a bigger bully than the Common Grackle. The large blackbirds have huge appetites, travel in big flocks and often take over bird feeders—eating everything they can get their beaks on.

The range of Common Grackles covers a hefty portion of the eastern United States and during migration season, they move in rapacious flocks that cause nothing but headaches and money.

Here are some things you can do to stop them from taking over your feeders.

Get feeders with small or collapsible perches

Dealing with Common Grackles is similar to dealing with squirrels: they both want to raid your feeders and will do anything to do it. Fortunately, both have many of the same weaknesses. The first is their size. By getting a feeder with a perch that closes when too much weight is on it, you can keep out grackles and squirrels. The smaller and more desirable birds will still be able to get in, however. An example of this is the Heritage Farms Absolute II Squirrel-Proof Feeder.

If you don't want a squirrel-proof feeder, you can also just get a feeder with small perches designed only for songbirds. Grackles will be too large to grab a hold of the perches and won't be able to eat the seed.

Put a cage around your feeders

Another squirrel-proof device that's equally effective on grackles is a mesh cage. Flocks of hungry grackles can easily devour suet and empty feeders in a matter of minutes, but they are much too large to get through the cage feeders designed to keep out squirrels. Again, smaller birds will still be able to get through the compartments in the cage.

Avoid tray and hopper feeders

When you see that flock of grackles coming into your yard, you should immediately pack up your feeders that are easy to land on until the grackles move on. Tray and hopper feeders are essentially platters for grackles to feast. You don't have to take the feeders down permanently, just until the grackles are no longer coming around.

Use black oil sunflower seeds to reduce spillage

Although you may be able to keep grackles from raiding your feeders, they may also be eating all the spilled seed on the ground. Birds can be pretty messy and dump much of the seed they don't like on the ground. To help birds avoid making a mess and attracting grackles, put black oil sunflower seeds into the feeder because birds will eat everything and won't spill very much.

Try using safflower seeds in feeders

Alternatively, grackles do not like safflower seeds very much, but birds like chickadees and nuthatches do. Grackles are not necessarily the pickiest eaters, so they might still eat safflower in certain situations, however.

If you can't beat them, enjoy them

Unlike European Starlings and House Sparrows, Common Grackles are native to North America and can be quite beautiful to look at. They have iridescent plumage and unique calls. If they're in your yard during a migration stopover, try to enjoy them for a little bit and they'll be out of your hair in a few weeks.
