We also visited Black Hole Marsh nature reserve, which is a large saltwater lagoon having two large bird hides, one in the middle of the lagoon (Island Hide) and the other overlooking both the lagoon and the Axe Estuary (Tower Hide). There were many birds to be seen, but just as at the Seaton hide, a 400mm lens was not really enough to get frame-filling shots of the birds. All the following taken with Nikon D700, 70-200 f/2.8G VR II and TC-2E III converter (400mm focal length equivalent): Heron Fishing on the Lagoon with the Island Hide in the background Axe Estuary from the Tower Hide Pair of Bar-tailed Godwits Little Egret Mallards on the Lagoon Lapwing Fallow Deer and Egret on the banks of the Axe Pied Wagtail on the thick green algae of Black Hole Marsh.
