Thanks For The Mammal Reads

From Oak Harbor, Ohio, Kenn writes: Way back last year -- on December 25th -- I wrote a post about a wild animal that we observed at our bird feeder. In case you don’t remember or didn’t see the post, here’s another picture of this wily creature:

Actually, if you didn’t read it, I’d like you to scroll back to Dec. 25 and read that post and tell me: could you tell that I was trying to be humorous, or was it just too subtle?

The reason I ask is that, in that post, I didn’t mention what kind of squirrel it was. I was trying to strike a familiar chord with all those people who have had their bird feeders emptied by voracious squirrels. This has happened to a lot of people, but it isn’t always the same kind of squirrel. In the U.S. and Canada there are at least eight species of tree squirrels, plus various ground squirrels and chipmunks, that will come to bird feeders at least occasionally. If I had started to get technical about the particular type of squirrel that was chowing down at our feeder, the post would have bogged down in detail.

It was sort of like saying: "Don’t you hate it when your neighbor’s dog barks all night?" instead of saying, "Don’t you hate it when your neighbor’s three-year-old female beagle-spaniel mix with three white paws and one brown paw barks all night?" If your statement is more general, it’s easier for people to relate.

Anyway, after that blog post was published, I got three anonymous comments -- one mild, two (not published) pointedly snarky -- taking me to task for not identifying the species of squirrel. "Do you think all squirrels are the same kind?" "Are you so narrow-minded that you can’t even identify the squirrels in your own yard?"

So -- okay, the animal at our feeder was an Eastern Fox Squirrel. Our area of northwest Ohio also hosts Eastern Gray Squirrel and Red Squirrel, as well as Southern Flying Squirrel, but the Eastern Fox Squirrel is more common out in the farm country with scattered towns and scattered groves of trees.

To quote from published information: "Very common in many areas east of the Rockies, in open woods and parklike areas with large scattered trees and an open understory. It is often found in the same forests as the Eastern Gray Squirrel, but because it favors more open habitats, it is more numerous in the midwest ... Less arboreal than some of its relatives, this squirrel spends a lot of time foraging on the ground ... Like most tree squirrels, Eastern Fox Squirrels have a varied diet. Acorns and other nuts are staple items, but they also eat flowers, buds, seeds, bark, fungi, birds’ eggs, insects, and sometimes carrion. They also raid bird feeders, but because they are not as agile as Eastern Gray Squirrels, they are more easily foiled by strategic placement of feeders in places they can’t reach."

I’m happy to say that the source of that information is the Kaufman Field Guide to Mammals of North America, written by Nora Bowers, Rick Bowers, and myself, published in 2004 with a slight update in 2007. So, um, to answer the question from one person who commented on the Dec. 25 post: Yes, I do know what kind of squirrel it was.

The book’s treatment of Eastern Fox Squirrel includes a full page of text, a range map, a diagram of the tracks, and six color illustrations. That’s more detail than some species receive, but every North American mammal is treated in the book. I hope I don’t sound too horribly conceited in mentioning this book, but I'm proud of the way it turned out. It’s an excellent guide -- not because of me, but because of hard work by Nora and Rick Bowers as writers and photographers, by Stacy Fobar as managing editor for the project, by Eric Powell on digital graphics, by expert consultants Christine Hass, Nancy Mann, and Ronnie Sidner, by my editor Lisa White at Houghton Mifflin Harcourt, and by more than 50 photographers who contributed to the book. If you’re interested in wildlife, I would encourage you to consider picking up a copy.

Okay, enough of this. Who cares about mammals, anyway? Let’s get back to birds!

A Special Gift: Wildlife at the Bird Feeder

From Oak Harbor, Ohio, Kenn writes: I don’t often blog about bird feeder happenings, but in honor of the holiday season, I wanted to let all of our friends know about a major triumph at our feeders. Kimberly and I are interested in all wildlife, of course, and sightings of wild mammals can be particularly exciting. What a treat, then, to actually attract one of these elusive wild creatures into our own backyard, where we can observe it and begin to learn about its habits.

Imagine how thrilled we were when we looked out the window on Christmas morning and saw this:


Yes, it’s a squirrel. If you have spent any time in wild habitats with tall trees, you may have seen these wary acrobats climbing about in the branches, far above the ground. Getting a good look at one, though, that’s another story.

Kimberly and I had glimpsed these wily creatures around Oak Harbor, but we had hardly dared to hope that we could actually attract them to our own yard. But here was one of these elegant wild animals right outside our window.

Of course I should have been satisfied just to watch from indoors, but I couldn’t resist trying for a closer view. When I eased out the door, the squirrel was instantly on the alert:

These wary creatures are endowed with keen senses, with sharp eyesight and with hearing and sense of smell far superior to man’s. I had taken the precaution of eating some salted peanuts before I walked out the door, to try to mask my human scent, but the squirrel detected me immediately anyway.



It was thrilling to be able to observe this shy treetop creature without even using a telescope, but I knew I could not push my luck too far. The squirrel undoubtedly would flee if I approached any closer than about 13 inches.

Friends of ours have put out feeders and have failed to attract squirrels, even after trying for five minutes or more. So in the spirit of the season, we should share the secret of our success in attracting this wild animal. After much experimentation, we have found that squirrels are only likely to feed on items that have some animal or vegetable components. They seldom eat pure plastic or concrete or metal, although they may chew on these materials. Even some items with an organic basis, like wood, may be only chewed up and not actually eaten by these picky and fastidious creatures. So the items placed in the feeder should have some resemblance to something edible. Price has an impact as well; somehow these amazing animals can detect the relative cost of different bird feeder items, and feast upon only those that are most expensive. Finally, squirrels seem to require a certain level of irony in their diet. A so-called squirrel "baffle," or one of those feeders jokingly labelled as "squirrel-proof," may bring them in from miles away to sample your most expensive sunflower seeds or suet mixtures.

Alas, I must have approached too closely, or perhaps the squirrel noticed that I was banging on the side of the feeder with a large stick. Fleeing on the wings of the wind, the shy creature sought refuge up in tree branches at a dizzying height, a full four feet above my head.


I had violated that boundary between man and wild beast. The squirrel was truly terrified. It would not come back down to finish scarfing down all the black oil sunflower seeds from the feeder until I had been back inside the house for a full fifteen seconds.

Whether or not you are blessed with a visit from a wild creature such as this, Kimberly and I both wish you all the joys of the holiday season and a healthy and prosperous new year.
