bird deterrent?

At what frequency do birds hear? Is it the same frequency dogs and cats can hear?

    They hear best in the frequencies of their own calls and songs and this varies with the species. You are on the right track, though. We had excellent success in getting nonmigratory Canada geese to leave golf courses by using "screamer shells". They look something like a .410 shotgun shell and are fired from a special pistol. You fire over the flock and the shell emits a piercing whistle. One greenskeeper had a big grin on his face when he told me that "his" flock had left for a competing golf course.

    They can hear as well, they just can't tell direction of the noise as well as cats/dogs, some of which use this for hunting. 

    Many birds generally excel at eyesight, some can see ultraviolet. Dog eye sight is generally poor. 

    Earlobes in carnivorans [and many other mammals] fulfill the function of tracking where noise is coming from. 

    Owls have similar capabilities but most birds do not.

    Birds are deterred by calls of their own species. That is why mockingbirds sing the songs of hundreds of different bird species They try to keep all other birds from their territory so that they can have access to as much food as possible since they raise multiple broods per season.
