WILSTONE RESERVOIR

Waders and Red Kites in the Chilterns

Situated in the Tring Gap on the Chiltern Hills, Tring Reservoirs were created in the 19th Century to provide a regular water supply for the Grand Union Canal and, as such, are owned by British Waterways. This walk takes in Wilstone Reservoir, the largest of the four waters that comprise the Tring Reservoir group and is managed by the Herts and Middlesex Wildlife Trust.

The open water levels vary throughout the year, with concrete banks on the northern side and muddy margins if the level is low. A tree-lined spit protrudes into the reservoir from Drayton Bank, where Grey Herons and Cormorants nest. A hide overlooks the spit and is the best spot for wading birds, as well as affording views across a large reedbed and willow scrub. Mature woodlands, arable farmland, hedgerows and scrub along the old canal arm combine to complete a bird-rich ensemble of habitats guaranteed to deliver an extensive species list.

Birds such as Cetti’s Warbler, Little Egret, Buzzard and Red Kite, which less than a generation ago were unknown, are today a given, while on the debit side, the likes of Corn Bunting, Tree Sparrow and Brambling are almost unknown and Willow Tit is extinct. Passerine flocks increasingly attract Firecrests, while Smew and Goosander are intermittent visitors most winters.

This walk is suitable to take the dog along and with a highly recommended pub and cafe at nearby Marsworth, there is no need to pack a flask. The area near the car park can get quite busy with fishermen at the weekends, so it is best to visit as early as possible or on a weekday.
