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.
