I'm wondering if anybody can enlighten me regarding bird distress
calls. I know that they have been used as deterrents, with varying
degrees of success (a nursing home in my neighborhood blasts a
distress call from its roof, with the speaker located next to a
plastic great horned owl. This is apparently supposed to keep pigeons
out of the AC units). I'm wondering if this will work to keep birds
breaking their necks by diverting them from a building with a lot of
glass.
What I'm interested in learning:
What type of call works best? Does it need to be randomized in some way?
Will the calls attract real predators? There is a fairly ambitious
Peregrine release project here in Chicago, and I'd hate to see a few
sparrows spared at the expense of the peregrines.
Any input on this would be most helpful.
