Population justification: The population fell to 788 pairs in 2006 following the 2004 tsunami, however, numbers since appeared to be recovering. Surveys conducted in 2009-2011 have resulted in an estimate of 376-752 breeding pairs, suggesting that the population has been stable since 2006 (A. P. Zaibin in litt. 2012), and indicating that there are c.750-1,500 mature individuals.
Trend justification: Although survey results from 2006, following the 2004 tsunami, suggest that its numbers had declined by 75-81% on the 1994 population estimate (Sivakumar 2007, 2010), preliminary reports suggested that a natural recovery was underway (R. Sankaran in litt. 2008), despite the worsening of some threats (Sivakumar 2010), and surveys carried out in 2009-2011 suggest that the population has remained stable (A. P Zaibin in litt. 2012).
