I know the answer, because they are not grounded and do not complete any circut, but I have a different analysis that I would like to explore.
First, why do you need a closed circuit? Because if you have a battery pushing current along a wire that ends, electrons will accumulate at the end of that wire and will eventually produce an EMF that negates the battery's EMF, is this correct?
Second, current that flows to homes is alternating, so imagine you have an alternating current source and wires that extend in both directions and do not connect to anything, once the current reaches the point where the EMF from the displaced electrons cancels out the source EMF the current reverses, basically the alternating current is pushing electrons to alternating ends of the wires, likes a half of a capacitor being charged and discharged repeatability.
Third, if you put a light bulb in this circuit, it should light light up, right? So I would imagine the bird would get shocked, because even tho there is no where for the electrons to flow out of the bird once they enter as required by Kirchhoff's law, since the current is alternating,they would go out the same path and the bird would be pumped full of electrons then drained of them.
But, the birds don't get shocked, so what's wrong with my model?
