If I were to design power lines which were friendly to cranes two things
need to be taken into account. First cranes fly in various weather types
and at different times of the day and night. Our family farms rice in the
Butte sink area on the north border of the Gray Lodge Refuse, north
Sacramento Valley. I have observed cranes landing in rice fields when fog
was so thick the cranes could hardly see me but once they did see me they
were quick to leave. I have also heard cranes flying at overhead at night.
It has occured to me the cranes need sound as well as sight when flying in
adverse weather conditions. Powerlines need to emitt some type of chimes
or clanging noise to alert the birds of the impending object in their
flight path. Fog horns alert humans to dangers I'm sure there is some sort
of noise the cranes would alert to. My name is Tim I work at Polson Middle
School, Polson,Mt. While working in the Big Hole Valley one summer I had
the pleasure of sharing the nearby marsh with a pair of sandhill cranes.
What a magnificant creature!
