Protecting Your Bird Feeders from
Pests and Predators
When you start feeding birds in
your yard, expect some unwanted guests. Many species
of birds and mammals enjoy not only the seed you are
providing, but sometimes even the songbirds you are
trying to feed.
Hawks
Please remember that in the United
States, it is illegal to kill, trap or harass native
raptors. In addition to hawks, eagles and owls are
protected by law. Try one of the following tips to
help keep the songbirds your feeder will attract from
becoming lunch for a hawk or kestrel:
- Place your feeder near shrubs or trees that will
provide dense cover. Many people hang their
feeders in trees to give the birds a greater
feeling of security.
- Feed birds early in the morning and only what
they will use in one day. Hawks and kestrels are
more often seen later in the morning and in the
early evening.
Cats
Cats cause the deaths of more
songbirds than any other animal. wild, or feral, cats
generally hunt only at night. Their prey is usually
mice and other rodents, so domesticated cats do the
most damage to songbird populations. It is a myth that
a well-fed cat will not kill birds or small mammals.
In fact, they will still kill their prey simply by
instinct. A study conducted in San Diego County
indicated that cats that were allowed to roam freely
may have led to the local extinction of several native
birds such as the roadrunner, cactus wren and
California quail. A U.S. and Great Britain study
showed that an outdoor cat can kill up to 1,000 animal
per year. Since discouraging a cat from chasing or
killing birds is nearly impossible, try some of these
tips:
- Don’t hang bird feeders from a fence where
cats can get to it.
- Remove hiding places that a cat can strike from,
such as low, dense shrubs. Or, you could plant
thorny shrubs that the cats are less likely to
hide in.
- Tie cut rose stems, thorny bushes, or barbed
wire to feeder poles to keep cats from climbing
the poles.
Squirrels
Squirrels love birdseed. They are
often very hard to discourage. As George Harrison said
in his book Squirrel Wars, "...it is a
biological fact that squirrels have more time and a
greater motivation (their own survival) to devote to
the fight, regardless of how long it takes." Here
are some tips to try to make it at least more
difficult for squirrels to raid your feeder:
- Slip cut two-liter bottles onto your feeder’s
pole. This will make the pole hard to climb.
- Place baffles underneath feeders.
- Move feeders away from trees where a jumping
squirrel can reach it.
- Hang feeders from thick fishing line.
- Hang a feeder from a clothesline that is strung
with small pieces of PVC pipe. When the squirrel
tries to walk on sections of pipe, they will spin,
sending the squirrel to the ground. This idea
works well on support wires, too.
- Don’t put too much food in the feeder at one
time. The birds will eat all of the food in the
morning and leave nothing for the squirrels in the
afternoon.
- Use squirrel-proof feeders with weighted perches
or cages to only allow small, light birds access
to food.
- Mix birdseed with cayenne pepper. It doesn’t
bother the birds, but the squirrels will hate it.
Bully Birds
Some birds like pigeons, jays,
starlings, blackbirds and house sparrows will try to
claim a feeder as their own. Try some of these tips if
you find that the aggressive birds are taking over:
- To deter pigeons, eliminate corn, chicken
scratch and grains from the feeder. Also, try
placing a garbage can directly under the feeder.
- Most bullies are larger than the birds
considered to be more desirable. By enclosing
feeders with large-mesh hardware cloth or chicken
wire, the smaller birds can pass through, leaving
the larger birds excluded. There are also
commercially made feeders just for this purpose.
- Sometimes it’s simply easier to put up several
feeders. Keep seed the bullies don’t like in one
and food they do like in another.
