These are scans from chromes taken on Tobago. We were also out in boats, worked our way through a mangrove swamp to a spot where scarlet ibis roost overnight, BUT they didn't come in until sundown, the sun sinking below the horizon when they started to fly in. Horrible conditions for using a camera with ISO 200 slide film (? - not certain what was in the camera as I used Velvia, Kodacrome, or a couple speeds of Ektachrome, but very rarely something with ISO as high as 400). Visually the ibis were wonderful, but capturing them in the gloaming with such slow film was pretty much impossible.
