Snow Birds

by OCMGA Master Gardener Tammy Borden

Winter is here. That means that most Ruby-throated hummingbirds have flown south to another whole continent, along with Baltimore Orioles, Rose-breasted Grosbeaks, Indigo Buntings and a host of other feathered friends we won’t see until Spring or early Summer. But that doesn’t mean we can’t longingly peer out our kitchen window in hopes of seeing some other feathered delights!

Winter Visitors

Believe it or not, Wisconsin winters are a “retreat” for some birds. There are several species of birds that migrate for the winter south to Wisconsin from Canada. One of these birds is the very common Dark-Eyed Junco. It is a beautiful small gray bird with a white belly. They are easily recognizable at bird feeders, feeding on thistle, cracked sunflower, and other smaller seeds. They are more often ground feeders. They love snow. I have seen them practically playing in a blizzard.

Another winter visitor is the Redpoll, a member of the finch family. Redpolls will not visit every winter. In fact, I only saw them for one season about ten years ago when Canada was experiencing an unusually harsh & frigid winter. In these cases, Redpolls will migrate south to Wisconsin in search of food. When they appear it’s called an irruption. It is almost like they are refugees in a foreign land.

White Throated Sparrows are another favorite sight on a dreary winter’s day. They are

White-throated Sparrow

commonly seen in winter in Wisconsin and at first glance may look like a plain old house sparrow. But not so! Look closely and you will see the white throat, yellow patches near its beak and the black and white stripes on its head. They prefer foraging on the ground rather than sitting on a feeder, so be sure to scatter some seed at the base of your bird feeder.

Goldfinches … “What?” you say. Many people believe that those “wild canaries” leave for the winter and are replaced with brown sparrows. Goldfinches remain in Wisconsin for the winter but lose their summer plumage. Continue to put out thistle seed for goldfinches and come spring, you will have a backyard of sunshine.

WATER

Rule number one: all living things need water, and providing a source for birds is critical in the winter months. Many heated bird baths are available from various retailers and can range anywhere from around $30 to over $100 depending on how fancy you want to get. The key if you get a bird bath heater is to make sure it is thermostatically controlled. This will help save on energy bills and only heat the water when temperatures are freezing. I have often looked out my kitchen window on a freezing morning to see birds perched all the way around my bird bath. It’s a wonderful sight to see.

FOOD

Birds in winter need to maintain as much body fat as possible. So it’s important to provide food that will help keep a bird’s metabolism up to keep warm. One of the best sources of fat and protein for birds is suet. Keep lots on hand in the winter. Woodpeckers love it and their stark plumage adds color to your life.

As far as birdseed is concerned, I recommend not purchasing inexpensive bird seed mix. Check the ingredients! Many mixes contain filler seeds like Milo and millet. A small amount of millet is okay, but Milo is a seed with an extremely hard shell that is almost impossible for most birds to open. Some cheap birdseed mixes contain up to 35% Milo, which is practically all waste material. In addition, it has very poor nutritional value. Personally, I just purchase plain old black sunflower seed for my larger feeder, and thistle seed for my tube feeder. These basics have worked well for me. I have also purchased some nicer mixes and combined them with a larger bag of sunflower seeds to offer some variety.

Remember to shovel away or press down the snow underneath feeders to help ground-feeding birds. Scatter some additional seed on the ground.

COVER

An important aspect of birding in the winter is to provide protection. Small birds are more vulnerable to hawks and predators in the winter because there is less cover. Some of this may require planning ahead by planting dense shrubs, evergreens and wind breaks. However, a simple way for those who use real Christmas trees is to simply place your tree about 10-15 feet from your feeder after the holidays are over. Another way to provide protection is to make or purchase a roosting box. Smaller birds like chickadees will use them to huddle together at night when resting and to escape the winds. Other possible cover includes wood or brush piles.

Don’t forget your feathered friends this winter! I’ve generally found that the more birds you have, the more birds you’ll get! By feeding them through the winter you’ll have a better chance in the spring of seeing new species dropping in to see what all the chirping is about!

Ground Covers

What is a Ground Cover?

Groundcover_6695A ground cover is any low-growing plant or group of plants that will make a living blanket over the area in question, crowding out weeds while providing visual interest. Most of the more common ground covers are rapidly spreading, long-lived perennials with soft stems, such as pachysandra, but low-growing woody shrubs like spreading junipers are often used also.

Ground Covers for Shade

Among the hardy herbaceous ground covers that are superb for shade are the European wild ginger (Asarum europaeum), which has rounded, glossy evergreen leaves and grows about 6 inches high, and barrenwort, or bishop’s hat (Epimedium spp.), which has semi-evergreen leaves that seem to flutter over its wiry stems.

Consider also lilyturf (Liriope muscari), with grassy evergreen foliage, and sweet woodruff (Galium odoratum), whose starlike leaves are, as its name suggests, fragrant; and an assortment of hostas.

There are a number of low-growing woody plants that are also good ground covers, including bearberry (Arctostaphylos uva-ursi), whose tiny evergreen leaves often turn red in autumn; several herringbone-patterned cotoneasters (including Cotoneaster horizontalis) and C. dammeri; and the St. John’s wort called Aaron’s beard (Hypericum calycinum), whose yellow flowers dot its dark leaves through the late summer.

Covering Hot, Stony Ground

When you say hot, dry, and stony, you’re describing the perfect environment for creeping thymes. There are dozens of these gracefully spreading, tiny-leaved plants, many with strong scents other than that of the classic herb.

Choices include lemon-, coconut-, caraway-, and lime-scented varieties. Or if you don’t want to grow hungry every time you take a step, there is a well-named wooly thyme, which has only a light fragrance. It forms a very low mat of silver-green fuzz that makes you want to stoop down and pet it.

Over Exuberant Ground Covers

Beautiful, easy, quick to spread. When you read these words in the catalog, they sound very enticing. But be careful what you wish for. Many of the most common ground covers are actually hell-bent on covering the earth. Once they have taken hold in the garden, they are very hard to eradicate, and there’s a good chance that they won’t stop when they reach the property line.
