My guess is their feet/claws are non-conductive.
I thought about being non-conductive but then why does the Bird-B-Gone work?
I suggest you go from 115 volts to 240 volts, so that not can you only remove the birds, but they will be cooked for dinner.
However, one word of caution, if you install the 240 volts and while you are doing it, if you see your wife with a hose.... jump of the ladder andRUN
