Tyttenhanger Gravel Pits is one of Hertfordshire’s best birding areas, situated in the shallow Colne Valley between St Albans and Hatfield (map; grid reference TL194052). The site stretches from Colney Heath in the north to the Willows Farm Village theme park (near London Colney) in the south and supports a range of wildlife habitats. The wide variety of birds includes resident Tree Sparrow and Yellowhammer at Tyttenhanger Farm. The site has also become the county’s foremost wader site.

History
Sand and gravel extraction has taken place on the site since 1982, and the site now features several flooded gravel pits. The main pit of interest to birders (to the east of the River Colne) is still used by Lafarge Aggregates Ltd as a source of water for washing the sand and gravel extracted from an active quarry south-east of Coursers Road. A noisy conveyer belt carries sand around the south and west sides of the pit.
Habitat
The site includes disused flooded gravel pits, areas of active quarrying, shallow pools, mudflats, parkland, open farmland and two small areas of coniferous and deciduous woodland (Garden Wood and Coppice Wood). The River Colne runs through the centre of the site. The main lake of interest to birders is the easternmost lake, on the east side of the River Colne. Its continuing use by Lafarge means that the water level can fluctuate considerably. The south-east of the lake is shallow. Two flooded gravel pits to the west of the River Colne are used for angling. South of the site is the Willows Farm Village theme park, which has a shallow lake. Coppice Wood, an SSSI, contains a good range of woodland species. Garden Wood was formerly used for paintball games and may become more attractive to wildlife now this activity has ceased.
Species
Birds
The site attracts a wide range of bird species. A detailed guide can be found at the Herts Bird Club website.
In winter the gravel pits generally support small numbers of Tufted Duck, Pochard, Wigeon, Shoveler, Teal and Gadwall, with occasional Shelduck, Pintail, Smew and Goldeneye. Waders include Green Sandpiper, Snipe and Jack Snipe, with Lapwing usually present and Golden Plover often in large flocks on nearby fields. The area around Tyttenhanger Farm holds a flock of Tree Sparrows (generally to be found in the hedgerow on the north side of the horse paddock). Along with other finches and buntings, including Brambling, these are attracted by feed put out by a shooting syndicate for Red-legged Partridge. The site also attracts irregular visits from Merlin and Peregrine, and Common Buzzards are seen regularly.
In spring the wintering waders are joined by Little Ringed Plover, Redshank, Greenshank, Ringed Plover and Dunlin. Rarer visitors have included Temminck’s Stint, Wood Sandpiper, Avocet and Stone Curlew. Wheatear and Yellow Wagtail are regularly seen in the fields and on the sandy banks. Common Tern arrive to breed on the shingle and Black Tern are often seen on passage. Hobby frequently visit the site and Osprey occasionally pass through. Hirundines are seen regularly and the commoner warblers can be seen or heard over the whole site.
In summer Redshank, Ringed Plover, Little Ringed Plover and Lapwing breed. Most of the common warblers also breed around the site. Yellow Wagtail have occasionally bred in the area.
In autumn, Green Sandpiper are again regularly seen and waders such as Black-tailed Godwit and Spotted Redshank may pass through. Migrant passerines include Whinchat.
Insects
A large Buddleia bush next to the bird hide attracts Red Admiral, Comma, Painted Lady, Small White, Peacock and Gatekeeper butterflies. Another butterfly seen in past years is the Brown Argus. Dragonfly species include Brown Hawker, which are particularly conspicuous.
Practicalities
Directions
The site is a mile or so north of the M25 at Junction 22. Turn off to the Bell Roundabout and take Coursers Road into Colney Heath. At a crossroads turn left along High Street and then fork back along Church Lane. Park at the end by the water works (TL 198058) and follow the footpath south-west into the site. Alternatively, from the Bell Roundabout, take Barnet Road into London Colney. Turn right to park in Lowbell Lane or cross the River Colne and turn right to the small car park at Riverside. From either parking place, head for the river and follow the footpath that leads north under the A1081 and past Willows Farm. Avoid the car parks around the fishing lakes (reserved for anglers and with a history of theft from vehicles) and at Willows Farm Village (reserved for visitors to the farm and customers of its shops).
London Colney is connected to nearby conurbations (St Albans, Hatfield, Watford and Barnet) by five bus routes: 84, 602, 632, 658 and 659. Route and frequency information is available from the website of London Colney News. Colney Heath can be reached from Brookmans Park station (Thameslink) by three bus routes: 200, 304 and 826. The 304 continues to St Albans and the 826 to Hatfield.
Access
The site has 24-hour free public access on a network of generally well-marked public or permissive footpaths. The access points mentioned above allow entry to the site along the Watling Chase Trail national path, which passes north-south through the area. Access can also be gained from the A414 on the site’s north-west boundary and from Coursers Road on the south-east.
Facilities
A rudimentary hide has been erected on the south side of the eastern lake, but at some distance from the water’s edge. Willows Farm Village has a cafe and a branch of In Focus, the binocular and telescope specialists. Shops at Colney Fields Shopping Park (near the M25 junction) include a Sainsburys Superstore and a branch of Marks & Spencer.
