Do high frequency noise emitters deter wood pigeons

I have seen a number of recent adverts claiming a 100% success rate but still sceptical ?. Apparently has a 10-15m range and is battery operated .

    Probably not.
    Birds hearing is poorer than human hearing.
    Birds hear best at frequencies between 1,000Hz and 5,000Hz
    Humans can hear between around 20Hz and 20,000Hz.
    High frequency would be defined as being above human hearing (20,000Hz) so birds would not hear anything from a high frequency device of any sort.

    I think that if it worked farmers would use it .... and they don't.  

    The city council here in Norwich uses recordings of Peregrine falcons to deter town pigeons from lurking on the library and city hall etc ... but we do have Peregrines here so maybe the pigeons know what they sound like and have a healthy respect for them.  And I'm not sure that you'd want the sound of falcon calls around your garden 24/7

    Is that a sonic transmitter just for pigeons? I've not seen that.

    A guy I know keeps pigeons and uses sonic rat deterants around the sheds. Doesn't seem to put the birds off but might not be the same type of thing.
    If you can keep your head, while those around you are losing theirs, you may not have grasped the seriousness of the situation.

    I got one that you point at cats to scare them off. It just sat and looked at me.

    It can take a while to start to work, but they do work very well on the whole. Different sonic detectors work via pulses different frequencies - for foxes, deer and cats.

    I see that this is is a motion sensor that works on a different premise - playing recordings of barking dogs or birds of prey. Also here.
