Lately the flocks of circling Canada Geese have been inspiring and I hear daily of more wild turkey sightings. Without a doubt, it is the wide variety of available feed on farmlands and forests that keep them here. Unwelcome visitors when they get into a newly seeded corn field, they have at times been helpful. This summer they did good service by feasting upon the devastating legions of armyworms that attacked grass lands in many parts of the county. Let's hope they have made a significant dent in future pest populations.
Insects are of course an important source of protein for birds and other wildlife.
Lands kept open are more than just a tourist attraction. They provide a prime habitat for many insect species critical to the larger food chain. Food, water, and cover. Some form of them could be just the Christmas present for which you have been searching. Water - Birds still need drinking water in the winter, eating snow and dripping icicles are other possibilities.
