Feeding birds in winter
RICHARD GAST, Cornell Ag Connection Press-Republican Plattsburgh Press Republican
According to the most recent census reports, bird watching may very well be America’s fastest-growing national pastime, with more than 65 million Americans of all ages putting bird feeders in their yards where they can easily appreciate them.
In fact, by some survey estimates, bird watching is America’s second most popular leisure-time activity, with birding buffs spending more than $2.5 billion annually on feeders and seed. Only gardening is more popular.
In summer and fall, most non-migratory songbirds feed primarily on insects and spiders. They supplement their diet with berries, seeds and other vegetation. But in winter, there are no insects, and the edible berries and vegetation that haven’t been eaten become buried under the snow and packed in ice. Across the North Country, devoted bird enthusiasts take pleasure and pride in helping their feathered friends survive the harsh winter months, dutifully providing them with food, water and shelter.
No matter where you live, you can put food out, helping to ensure the survival of our feathered friends. Many bird watchers simply scatter seed on the ground, or more accurately, atop the snow and ice on the ground. And many birds actually prefer ground feeding.
But, birds feeding on the ground can be easy prey for cats and other predators, such as hawks. Besides, ground feeding is a wasteful practice. Large quantities of seed unavoidably become covered with snow. And prolonged exposure to moisture can result in contamination by mold and bacteria, as well.
