Emlen who proved this.
Using what later was called an "Emlen
funnel," he put an indigo bunting
experiencing migratory restlessness,
or Zugenruhe, into a funnel-shaped
cage that he had lined with paper, and
supplied with an ink pad perch at its
bottom.
The bird repeatedly leaped from the
ink pad to the funnel's side, leaving its
footprints on the papered wall.
In that way, the bird left a record of
its migratory direction and depending
on its hormonal condition, oriented
north or south.
Emlen followed this by proving that
those songbirds that travel at night use
the stars as a guide, specifically the North
Star - Polaris - which stays in the same
position all night, and the Big Dipper
and other nearby stars that rotate around
Polaris counterclockwise.
In addition, Emlen found that indigo
buntings learned their way as young birds
watching the sky at night.
Since his work, other discoveries about
bird migration continue to be made,
showing birds appear to use magnetic
fields to orient themselves, too.
Indigo buntings breed from the

Great Plains eastward to the Atlantic
seaboard and from southern Canada to
the southern United States. They then
head to their winter homes.
Many indigo buntings return to
the same sites both in their wintering
grounds and their breeding grounds,
according to a variety of studies,
although the males seem to be more
faithful to their home grounds than
females are.
It's intriguing to realize that those
males I see every year sitting on the same
singing perches may be as wedded to our
habitat as I am.

Dear Game Commission,
Thank you for the Game News subscription we receive here at our small school
in Cambria County. Each month the magazine is placed in the school library for all
110 students to enjoy. Nick Rosato's art is truly missed, but the new format is eyecatching. We even had a stocked pheasant wander from a local game lands to our
front door one day last fall. It wasn't permitted entry, though.
- Pauline Horvath, Northern Cambria Catholic School, Nicktown, Pa.
