Saltmarsh Sparrow

The Saltmarsh Sparrow is a tidal marsh songbird and the only bird species endemic to the ACJV; it is found nowhere else on earth. Their small population (~60,000 individuals in 2012) has been declining at an alarming rate of 9% per year since the 1990s. Under the current trend, scientists suggest that the population could collapse within 50 years unless something is done to stabilize the downward spiral. Nest flooding due to sea level rise is the greatest threat to their populations followed by depredation of eggs and young.
