There may be times when crows annoy you, but humane solutions
do exist.
Theft from the garden: Generally, crow damage in
gardens is slight enough that they can have a share with plenty
left over for us. Crow damage to corn may be an exception,
however. Visual deterrents are the first—and probably
best—response. Start using deterrents as soon as damage is
observed to ensure effectiveness. Bright and flashy objects,
such as pie tins and Mylar party balloons, can be very
effective at repelling crows and cost little or nothing. Garden
stores often sell reflective Mylar tape that also deters crows.
A holographically embossed tape, sold under the brand name
"Irri-Tape," is especially effective and can be ordered from
Bird-X, Inc. 800-662-5021.
Competition with other backyard birds: As natural
predators of smaller birds and their nestlings, crows might
have some negative effect on the songbirds in your sanctuary,
but it is rare that they would dissuade other species from
visiting, feeding, and nesting in your yard. Try to enjoy crows
as you do your other backyard sanctuary visitors.
Trash rummaging: Many animals go through trash cans.
Although crows may scatter trash by day, scattering done in the
night is more likely the work of dogs or raccoons. Solve either
problem by using secure trash receptacles with tight-fitting
lids, or weighing the top down with a heavy object.
Roosts in undesirable spots: Successfully altering
roosts or dispersing birds from them involves tactics that
require experience and skill. Non-invasive methods can be
employed with success, providing that the timing is correct and
that the measures used to disperse the crows are carefully
planned and carried out.
