Alternative control methods for starlings on farms
Starlings
somearial begin to use barns as winter roosting areas when the weather
turns cold in british columbia. Their droppings can cause fouling
of cattle feed and other filth problems leading to the need to control
the birds. In bc european starlings are classified as schedule c
wildlife. This means that they may be captured and killed anywhere
and at anytime in the province. Starling nests and eggs may also
be destroyed.
Traps may be used to reduce starling numbers and the populations
of other nuisance birds. There are a number of sizes and styles
of bird traps, some homemade and others available from commercial
sources. A trap frequently used for the capture of starlings
is an adaptation of the "australian crow trap".

Although it can be of almost any size, the most
common dimensions are 2 x 2 x 2.5 metres. The trap frame is made
of pipe or lumber and covered with small mesh poultry wire. The
birds enter through small openings in the top and the trap design
prevents them from escaping. The trap is baited with food, and
if possible, live decoy birds. The use of decoy birds usually increases
trapping success.
Barriers that restrict access to barns or potential
roosting sites within barns can be useful in discouraging starlings
from taking up residence. Examples of bird barriers are:
 |
|
- Galvanized
wire mesh screen,
- Bird
netting,
- Stainless
steel wires, wire prongs or spikes spaced along the entire
length and width of landing surfaces.
(a low-tech
equivalent
is to drive nails through strips of old tires or inner
tubes then affix these, points up, where needed.) these
are especially
useful on rafters above feed bins / troughs.
|
| Although expensive, the installation of various patented
spiked or pronged bird barriers provides long-term protection
from bird problems. However, instead of using barriers to exclude
birds you may want to "fight fire with fire" and
use barn owls to discourage starlings from roosting in barns. Some reports indicate that significant declines in rodents
and starlings were noted after barn owl houses that were set
up in barns were occupied by the owls. After you've installed
nest boxes for owls you might consider contacting veterinarians
or wildlife rehabilitators in your area to adopt an owl. |
