Population justification: The global population is estimated to number 2 million mature individuals (Partners in Flight 2019).
Trend justification: The species is undergoing a small decline (Partners in Flight 2019). This decline is thought to be caused by the destruction of wetland edge habitats throughout its range (Ferguson-Lees and Christie 2001).
