Ha ha, yes, I like the idea of recycling the telephone power back
into the grid!  Perhaps the phone power comes from solar powered
substations?  I will let others comment on whether this power would
be useful for your mic.

You will need to be a bit careful with long leads, make sure you
don't pick up electrical interference.

People do say phantom powered mics are less noisy than battery
powered ones.  I don't know your particular mic, so cannot comment.

Your feathered family in backyard sounds wonderful - I am jealous!
