I had always read, and heard, that pishing didn't work in Europe. I have
tested this assertion in various localities, mostly northern France, the
vicinity of Copenhagen, and Russia near St. Petersburg. My experience
demonstrates that these assertions are false.

Northern European passerines react immediately and strongly to pishing.
Walk along a hedge row, in a woodsy park, or a neglected pasture with brush
or tall weeds. Hear the birds all around. Pish. Note the sudden, stunned
silence. Hear the sound of little wings as they bear their panicked owners,
hugging cover, on a directional course 180 degrees removed from the pishing
sound.
