In Spring Dartford Warblers and numerous other small bird species nest in the gorse. Peregrine Falcons, Ravens, and the occasional Lesser Whitethroat can also be seen flying gracefully between the headlands. Sea birds are also in abundance at this site, with great opportunities to see Gannets, Gulls, Fulmars and Shags. However, the most famous residents of the valley have to be the  multi-horned Manx Loaghtan sheep and the characterful red-billed Choughs.

The sheep were introduced in 2016 as part of a conservation grazing scheme to improve the habitat and reduce the impact of bracken. After a number of years the grass sward began to return which enabled the re-introduction of the Chough after more than 100 years absence. This was part of a joint project known as Birds on the Edge between Durrell, the Department of the Environment and the National Trust to help safeguard Jersey's farmland and seabirds. At the moment approximately 17 Choughs are resident in the area, and are a wonderful sight to behold as they deftly fly above the cliffs enjoying the strong air currents.
