This dramatic capture of a couple of Philippine Ducks chasing each other over the swamp waters of Candaba replaces the foursome in flight of the same species in my Top 25 list.
The only endemic duck of our islands, this bird is one of the biggest reasons why I purchased the Sigmonster. These creatures are very shy and difficult to approach on account of hunting pressure. This pic was taken at a distance in excess of 70 meters and heavily cropped, yet image quality is still impressive. The sweet late afternoon light mitigated the harsh reflections off the water.
