Ask Birdsqatch: Feeder Marauders

A raccoon raids a backyard bird feeder in Quebéc, Canada.

Dear Birdsquatch:

We love bird feeding in the summer months at our house. We recently moved from a home in town to one out on the edge of town, adjacent to some woods and large fields. One morning late this spring, after filling our feeders the evening before, I was astonished to see the feeders completely empty. Something had emptied them overnight. We never had this problem in town, so I'm guessing we're feeding some new creatures here in this more rural setting. Any ideas who or what it might be and what we can do to keep them from emptying our feeders?

Dear Jimbo,

This is the first time I've ever answered a bird question from someone named Jimbo. I've answered bird questions from folks named John Boy, Jambo, and Django, but never Jimbo. It's a cool name.

You are correct in your guess that you've got some new visitors. Now that you live in a place with more natural habitat and more habitat diversity, it's practically guaranteed that you're going to have more wildlife around you. I'm no ornithologist—in fact I'm just a simple sasquatch that loves birding—but I feel certain that the reason your feeders were emptied over night is not due to a bird. All the birds that eat seeds, nuts, or even suet/suet dough are daytime (or diurnal) foragers, meaning they seek their food during the daylight hours. There's a different guild of creatures that are out and about during the nighttime hours—and a few of these are prime suspects in this mystery.

From smallest to largest, here are a few of the likely perpetrators for your backyard crime: white-footed mouse, southern flying squirrel, striped skunk, Virginia opossum, raccoon, and white-tailed deer. All of these mammals are known to visit bird feeders at night to partake of the seeds and nuts and other yummies we offer. The mouse, opossum, and raccoon are all expert climbers, and can get up an unbaffled feeder pole and park themselves on a feeder for a gorging session. The flying squirrel and deer can also gain direct access to a feeder—even a baffled one (hint: one of these animals can fly). In my wanderings I've seen lots of feeding destroyed by mammalian visitors during the warmer months.

While I have never done this myself, I can tell you these destructive visits come during the season when mammals are taking care of ravenous young, and a bountiful source of food—like all the seed at your feeding station—simply can't be ignored. Just be happy that you don't have black bears in your neighborhood. While a raccoon might chew up or even steal your feeder, a bear will bend the pole over and completely destroy your feeding station.

There are three things you can do to foil feeder marauders:

1. Feed only as much food as your birds and daytime visitors will consume in one day. If your feeders are empty at night, there's no reason for anyone (including me) to stop by for a nosh.

2. Bring your feeders in at night and replace them in the morning. A bit labor-intensive, but very effective.

3. Suspend your feeders from poles that have a predator baffle—a barrier that prevents anyone or anything from climbing up the pole to get to the feeders. In order for this to be effective, you will need to place the baffled stations feeder poles far enough from trees, deck railings, outbuildings, clotheslines, trampolines, and other potential launching pads to prevent squirrels and others from leaping directly onto the feeder. My friends at Bird Watcher's Digest have easy baffle-making plans on their website. Check it out here »

In my experience, mice and flying squirrels will take some of your food, but not all of it. Skunks eat only what's on the ground and easily accessible. Opossums will climb to get to a feeder, but won't destroy or swipe the feeder. Raccoons are bad news for a feeder—they'll clean you out and steal the empty feeder. Deer will clean out a feeder if they can, but they won't destroy it. For bears and sasquatches, plan on taking the feeders in at night. To keep the sasquatches placated, it's a good idea to leave a whole pie out on the deck railing at least once a week. Squatches seem to like blueberry.

Jimbo, I hope this answers your question. Keep on feeding those birds, and I'll see you around.

  • I am excited to have my daughter’s tree this year, since my landlord has removed the lovely yew next to my patio, which was the only shelter for birds at my feeder.

  • Goldfinches will continue as long as Swiss chard is available. I'm watching one eating chard right now (mid-November in Vermont).

  • Birds are on the decline though sunflowers are rarely touched and for weeks hardly .eaten. I'll try a few sparing nuts on the table and a fat ball broken for jackdaws and tits but mealworms were a summer favourite being my go to choice

  • I’ve been enjoying goldfinches eating coneflower/ echinacea seeds in my new pollinator garden! I will leave the plants out all winter for them if the seeds keep that long? Or should I deadhead and put them in a dry area? Im in CT and thought they migrated, but didn’t know they put in winter coats! What do they eat in winter without bird feeders?

  • Hi Gary, I will pass your question along to Birdsquatch next time I see him. He knows infinitely more about nocturnal wildlife than I do. Where do you live? That's pretty important in figuring out the answer. But the thief could be raccoons, deer, or flying squirrels. Do you live in the woods? Are there trees near your feeder, or must the culprit climb a shepherd's hook or pole? Dawn Hewitt, Watching Backyard Birds
