Winter weather will soon be
here in many parts of the country, yet many of us enjoy our wild birds
year-round. Should you continue feeding them in winter? What should you feed
them, and how should you go about it?
The "conventional wisdom" has always been that you should feed wild birds in
winter because their normal source of food – small seeds and insects – has
dramatically diminished. But is the conventional wisdom correct? By attracting
birds to our feeders, are we making them too dependent on a free source of food,
and weakening their ability to find food on their own? Do we actually put birds
at greater risk because of cats and flying into windows?
These are not easy questions to answer because there has been little research
into the subject. However a three-year study of chickadees by the University of
Wisconsin found that winter survival rates were highest among chickadee
populations that were fed – but only during the harshest winters. During more
moderate winters (and lower latitudes) there were no significant differences in
survival rates and spring hatching rates between chickadees that were fed and
those that foraged for themselves.
Squirrels and Raccoons are a constant problem, as they will empty a feeder,
denying your wild birds their food. They will destroy a wood or plastic feeder
by chewing though it, so the additional cost of a well-made feeder is money well
spent. Some squirrel-proof feeders are quite effective, but proper installation
is the real key to keeping moochers off your feeders.
Maintaining your feeder. The most important part of maintaining your feeder
is ensuring that the food is fresh and clean. A huge feeder with a "ten pound
capacity" is not necessary or even desirable because it is likely the food will
spoil before it is eaten. Some very good tube feeders will hold a lot of food,
but the purpose of the long tube is to prevent squirrels from hanging from the
top, not for huge food capacity.
After a rain or period of damp weather, inspect your feeders and discard any
food that has gotten wet. Wet food will coagulate in the feeder, blocking food
from naturally dropping to the feeding ports. Also, wet food is a breeding
ground for algae and mold that will discourage birds from eating and may make
them sick.
Set up more than one feeder with different types of food – perhaps sunflower
seeds in one, and finch food in another.
Your feeders should be installed to minimize the chances of predation. The
primary preditors are cats, so the feeder must be installed so that cats cannot
climb or jump to the feeding area.
Bottom line – don't feel you are doing your birds harm by feeding them during
the winter. Follow the above suggestions, and you can enjoy your wild birds all
winter long.
