(Passerculus sandwichensis princeps)
STATUS: Special Concern
(Only the Princeps subspecies is special concern. All other Savannah sparrow subspecies are not at risk.)
Sable Island, Nova Scotia
Maine, Vermont, New Hampshire and Nova Scotia
The savannah sparrow breeds mainly only on Sable Island and winters along the mid-Atlantic coast.
The species eats insects, larvae and other small arthropods. In the winter, it eats seeds.
It returns to its place of birth to breed (called philopatry). Since Sable Island is very isolated, this species rarely breeds with other subspecies.
