However, per Birds i*witness Malaysia, there have been a few more records since 2000, 2 in Guamantong in 2000, Sandakan Bay in 2007, 1 in Kinabatangan in 2010, and 4 in Lahad Datu in 2011.
My friend Jason photographed one in Sukau in 2008.
I finally had a chance to see and photograph this lifer in Tawau on 5th August 2012, in a pond near the Tinagat sea side. It was foraging near the grassy bank of the pond, we managed to take a few record shots before it disappeared into the thick grass.
