In Virginia, the migrating flocks of mixed blackbirds (grackles, red-wing blackbirds, starlings and cowbirds) would descend on our bird feeders during spring and fall migration. One moment we could have finches and cardinals eating at the feeder and the next minute, the yard would be filled with hundreds of blackbirds clamoring for bird seed. Migration lasted for about 2 – 3 weeks and the birds were gone.
We think we know where they were all going in the spring… to New Hampshire where we now live. Experts say that as food becomes more plentiful in the warmer months, feeders account for less than 25% of most songbird’s diet. But it must be 90% of the grackles’ diet. We took the seed feeders down early but continue to feed our hummingbirds and the woodpeckers with suet feeders pictured below….that is, until the flocks of grackles found the suet. In numbers, they could tear apart a suet cake in two hours.
My daughter showed us her grackle-proof suet feeder that worked for them so mister gardener got to work to build one for us. He crafted the new feeder to fit the suet cage, which he fixed horizontally beneath the structure, pictured below:
The suet is caged just inside the structure to allow clinging birds to hang on to the bars of the cage. The grackles (and squirrels!) try their hardest but so far have been unsuccessful in hanging upside down. The birds we enjoy have no problem hanging on to the horizontal cage. The noisy chickadee families, the nuthatches, several kinds of woodpeckers and the titmice visit our new feeder and entertain us…. all dining upside down.
