At least 70 bald eagles were counted in Massachusetts on Friday as part of a nationwide annual survey of the bird.
Bald eagles are considered an endangered species by state wildlife officials. But thanks to restoration efforts, eagle populations have gradually increased since almost going extinct nationwide in the 1960s. Each winter, teams of volunteers and MassWildlife staff spread across the state to count eagles near rivers, lakes, reservoirs and the coastline.
WBUR's Sacha Pfeiffer visited an eagle-counting site on the North Shore and has this story.
