Greg,
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!
