Preventing Conflicts With Woodpeckers
Flickers that have been crowded out of their wooded territories will readily use alternative structures for drumming, seeking food, or excavating a cavity. So the flicker that awakens you in the spring, drumming loudly on a gutter or metal flashing, is making good use of the habitat you are providing. For this reason, don’t remove dead or decaying trees in the hope of driving flickers away. That makes it more likely they may investigate your house for food or a nest site.
The following are descriptions of flicker activities and suggestions for ways to remedy problems. Success will depend on timing, the availability of food and shelter, and the woodpecker’s previous exposure to the tactics suggested below. The homeowner will have to weigh the trouble and expense of control against the scope of the damage caused by the bird or birds.
Scare the flicker away from a drumming site by hanging strips of Mylar scare tape or aluminum pie pans or floating Mylar party balloons in front of the area of activity.
1) Drumming: A flicker drums to communicate with a mate or to proclaim its territory and attract a mate. This typically happens during the breeding season (mid March to June), but may continue into July. For reasons that are not fully understood, drumming may also occur for a short time in the fall.
Drumming is the most common reason for flickers to use buildings, and while it may be annoying, the bird’s activity usually does not penetrate completely through wood siding.
Flickers will return year after year to the same house because it works for them; they attract a mate this way. Thus, a flicker that has been using the same location for several years will be hard to move.
To discourage drumming, try a combination of the following strategies:
Scare the flicker by hanging strips of Mylar scare tape or floating Mylar party balloons in front of the area of activity. When using scare tape, strengthen each strip by attaching a piece of duct tape or nylon packing tape to each end. Tack or nail one end to the outer end of the roof soffit, just under the gutter, and attach the other end to the side of the house. Before attaching the bottom, twist the tape 6 to 7 times and keep the tape loose enough to provide some slack. The slack and twisting are necessary to produce the shimmering effect. Apply these tape strands at parallel intervals of 2 to 3 feet.
You can also try hanging aluminum pie pans horizontally along a rope or section of twine. Run one end of the rope to a convenient window and fasten it to an object inside the house. Whenever you hear drumming, jerk on the string to make the pans move.
Some people have had success with stapling large rubber spiders in the vicinity of the drumming birds. Large, black rubber spiders are available from most party stores. The Birds Away Attack Spider is vibration/sound activated and will respond to the drumming of woodpeckers, by dropping down on a “web” cord. Batteries then retract the spider back up the cord, where it waits for the next unsuspecting woodpecker to arrive.
Scaring the flicker by shouting and banging pans outside a nearby window may provide temporary relief. A squirt of water with a garden hose can have a similar effect. Again, flickers living in urban areas likely will have grown accustomed to such noises and activity, and the results will be short lived. (Note: Scaring flickers away from a nest containing eggs or young is illegal.)
Create a barrier by covering or wrapping the gutter, down-spout, or other drumming site with a sheet, tarp, burlap, or other material. A large area of siding can be protected by hanging a sheet, tarp, or bird netting from the roof gutter or eave. Be sure to cover any ledges or cracks the bird uses as a foothold while drumming. If you cannot fasten the material to the gutter or eave, attach it to a board that has been temporarily fastened along the top of the wall.
If a single board on the house serves as a toehold, heavy monofilament fishing line or stainless steel wire can be tightly stretched approximately 2 inches above the landing site to prevent the flicker from perching.
Repel flickers by applying a commercially available, nontoxic woodpecker-protective coating spray where activity is taking place. The spray exudes an aromatic and taste deterrent when pecked.
Prevent flickers from accessing the side of a house by creating a barrier with a sheet, tarp, burlap, birdnetting, or other material. A note on where to get materials: Mylar scare tape, Mylar scare balloons, bird netting, and woodpecker repellents are available from farm supply centers, nurseries, and on the Web (search for “bird control supplies.”) Some pest-control companies sell heavier netting with a larger mesh than common bird netting used to protect fruit. Such netting is not as likely to create problems for small songbirds, which sometimes get caught in the smaller mesh.
2) Seeking Food: Flickers inspect tree trunks and branches for wood-boring beetles and other insects throughout the year. If a flicker pecking is not restricted to one location on your house, and if it occurs any time of year, the bird is probably gathering insects, or their eggs or larva. Physical evidence of this behavior includes soft pecking in straight lines that result in dime-sized holes.
Once they have established a feeding pattern on a house, flickers can be very persistent, and the holes they create may serve as visual attractants to other flickers. So, it is important the get them to stop as soon as possible.
Note that the flickers may be doing you a favor by drawing attention to an insect infestation. As a temporary measure, you can create a barrier between the bird and food source by using one of the techniques described earlier.
For the long term, you’ll need to control the insects if you have an infestation, and then make any necessary repairs or modifications with wood filler, caulk, or other materials. You may want to consult a licensed pest-control operator on how to remove the insects and eliminate future infestations.
3) Excavating a Nest or Roost Site: If you find a round opening about the same width as the flicker in the siding or other boards, the woodpecker is probably excavating a cavity to nest or roost in. Often the birds pull out insulation from between the walls and there may be evidence of this below the new hole.
In the spring or early summer, assume there is an active nest with eggs or chicks inside. Scaring flickers away from an active nest is illegal. So, after the young birds have left the nest (generally by mid-June), immediately seal the opening to prevent starlings, house sparrows, squirrels, or other animals from using the cavity.
If a flicker has nested or attempted to nest in a wall, you might consider providing a nest box specially designed for a flicker as an alternative nest site. Flickers commonly use nest boxes. A nesting flicker may defend its territory and keep other flickers away.
