February is National Bird Feeding Month in North America and it's with good reason. For those parts of the continent that have cold, nasty weather February is perhaps the most difficult month for wild birds to survive. It's still as cold as certain parts of a brass monkey on an iceberg and the natural food crop (berries, fruits, nuts, etc.) may be mostly depleted. Warmer weather food sources such as insects, tender buds of trees, and plant nectar will not be available until later in the spring. Or if the weather is not cold and icy or snowy, it's wet and the wind is blowing. Tough conditions.
We've had yet another snow in SE Ohio so the feeders are hopping even more than usual. The food our birds go after most ravenously is the suet dough that Julie makes (although I do help out on the large-batch stirring duties).
Our blue jays are particularly hoglike with the suet dough. They use their food-stashing ability to carry off large throat-fulls of the dough. We've learned to crumble the dough into small pieces to keep the jays from taking golf-ball-sized chunks away to the woods to cache. But every now and then (and don't tell Zick) I put out some wads of dough just to see how excited this makes the jays.
Blue jays (and several other jay species) play an important role in the vitality of our forests. They cache (or hide) food for later consumption as a hedge against food shortages. Most of the food they cache is in the form of nuts such as acorns from oak trees, hickory nuts, pecans, and beech nuts which the jays bury under leaf litter or pine needles or in loose soil. Only a percentage of these cached nuts are ever recovered by the jays that buried them. Many of the un-recovered nuts germinate and become saplings and eventually full-grown trees, often growing far from their 'parent' tree. In this way jays help to keep our hardwood forests diverse and healthy.
When I lived in the East, I used to see this diner—and I can't even remember where—called Squat & Gobble. I loved that name and it's a perfect description of how our jays take in the suet dough from our bird feeders.
It would surely be nice if the suet dough the jays cache would sprout into a suet dough tree from which we could harvest ready-made suet dough. It would save a lot of lard melting and two-handed mixing.
Here's a series of images of a blue jay at the suet dough.
