  Ospreys, also called sea hawk or fish eagle, are found all over the world including here in New Hampshire, But wherever they live, when the temperature drops the birds head for the tropics. For juveniles that first migration is a crucible that only 25 to 40 percent survive.

A project in New Hampshire is tracking Granite State birds and learning about the many misadventures they have between their departure in the fall and return in the spring.
