Heading South: Bird Migration and Human Impact

Sep 30, 2016

It's not uncommon at this time of year to look up and see the familiar shape of geese migrating south, or the broad wings of raptors riding the wind currents.  We discuss the different species of birds, including songbirds, who make an annual migration, and how they equip themselves for their journey. We also examine how humans have influenced the abundance of the species, and what we can do to help lessen our impact here on the ground in New Hampshire.

Birds mentioned during the broadcast:

The Arctic tern  is notable for its long yearly migration from its Arctic breeding grounds to its wintering grounds off of Antarctica.  It may cover perhaps 25,000 miles, and is the farthest yearly journey of any bird.
