Is It Bad to Feed Wild Birds?
by: Mike Kershaw
Is there evidence that feeding birds in your backyard will lead to bird death?
Some think that once birds rely on your feed, they will not be capable of gaining
their own food, especially during hard times such as winter.
Some feel that birds will rely on the food provided by you and that they will
lose their ability to find their own food. Other experts think that our feathered
friends are much more resilient and will discover new sources of food if the feeder
repeatedly is empty and they can't support themselves or their young.
As reported in Bird Watcher's Digest, researchers Margaret Brittingham and Stanley
Temple found that black-capped chickadees take, on average, only 20-25% of their
winter food requirements from feeders. But, they also demonstrated a significant
correlation between an individual bird's ability to survive the winter and the
use of bird feeders.
Evidence shows that aves that eat food provided by humans through feeders had
an annual (not just winter) survival rate that is 8% higher (up to 95% from 87%)
than those birds that don't eat food provided by humans. For winter (as opposed
to month-to-month), 69% of the feeder using birds survived the winter where only
37% of wild non-feeder using birds survived the winter.
If more wild birds survive the winter when we feed them, what are the implications?
In simple terms, it means that without our help, a higher number of birds fail
to survive the winter. If we help, more birds will survive. Curiously, even though
our food supply will decrease the winter death rate, our avian friends will not
completely rely on us. If your bird feeders are consistently empty, these amazing
animals will almost always take flight to find another source of food on their
own. You will also notice that in the spring, when food abounds, the birds are
not as active at the feeders as they are in the winter when food is harder to
find.
We can only suspect that different birds, like people, have different levels
of dependence. However, the truth is that our avian friends will adapt. If one
fails to continue a consistent feeding program, the birds will adapt and search
for food.
I recommend that if you start a bird feeding program, stay consistent. It is
best if you fill the feeders at the same time every day or whatever interval you
need and ensure that the feeders do not stay empty for extended periods. For really

Also, if you plan to go on vacation or holiday, plan for your absence. If you
will be gone for a short time (a few days), overfill your feeder and spread some
on the ground around trees or bushes near your feeders. If you are going to be
gone for an extended time, ask your friends, neighbors, or relatives to check
and fill your feeders on a consistent basis.
As for winter feeding, it is more serious. Some bird populations may not migrate
to areas of higher food availability if there is a reliable source near their
summer habitats. Thus, if you feed birds on a consistent basis over the spring
and summer, it is important that you are extremely consistent in the winter, when
some species may rely on your food to survive.
To make a long story short, it is better for survival rates if you feed wild
birds in your yard. But if you decide to feed them, it is ideal if you are consistent
in your feeding.
