Response Statement - Savannah Sparrow princeps subspecies
This songbird is largely restricted to the sandy dune systems of Sable Island, NS. The population has increased over recent decades and now shows signs of stability because the island has reached carrying capacity. The bird is not prone to human disturbance because the breeding location is well protected. The subspecies is also multi-brooded and currently experiences good nesting success, which confers good reproductive potential to cope with potential catastrophic events. Nevertheless, its breeding range is restricted to a very small area of Canada, and it has a relatively small population. It is also exposed to ongoing threats associated with development of its shoreline wintering habitat in the eastern U.S., and is vulnerable to sea-level rise and increasing frequency and intensity of Atlantic storms that are projected to occur as a result of climate change.
