I had a spare hour so I walked over to Bird Island with my notebook. As soon as I entered the park I could hear the bustling from the lagoon. To my great pleasure, I found myself able to identify many of the inhabitants on sight, without the aid of my guide. While the Black-bellied Whistling Ducks maintain their substantial majority on the island, there seems to have been an influx of White Ibises, who are now a veritable presence on and around the shore. A female Anhinga was resting atop a stray branch in the middle of the lagoon, contorted beyond initial recognition. She dove swiftly into the water and disappeared from sight. I was anxious to see an Anhinga demonstrate its mythic, snakelike swim, but the bird must have died beneath the surface, because I saw no sign of her after.
