The recording area of Hertfordshire (area 20 in the Watsonian system) is co-terminus with the ceremonial county of the same name. Hertfordshire (abbreviation Herts) is a county in southern England (one of the so-called ‘Home’ counties), bordered by Bedfordshire to the north, Cambridgeshire to the northeast, Essex to the east, Buckinghamshire to the west and Greater London to the south. The county has an area of c. 1,600 km2  (600 square miles) and a population of around 1,200,000 people. The largest settlement is Watford, followed by Hemel Hempstead, Stevanage and St Albans, and the county town is Hertford.

Elevations are high for the region in the north and west. These reach over 240m in the western projection around Tring and along The Ridgeway, which is in the Chilterns, a long-distance national path on the Bucks border. The county’s borders are approximately the watersheds of the Colne and Lea; both flowing to the south; each accompanied by a canal. There are chalk streams some with old watercress beds and some pits from gravel or chalk extraction. Hertfordshire’s undeveloped land is mainly agricultural and much is protected by green belt. It is least populated in the east with mostly arable farming. Beech woodland is most often at the higher elevations.

Birding Hertfordshire

Hertfordshire is a relatively under-watched county and over the years has shown that it can turn up rare birds just like any other county – Paddyfield Warbler, Lesser Scaup, Red-breasted Flycatcher, Falcated Duck, Yellow-browed Warbler and Solitary Sandpiper are just a few examples.

Among the most popular birding sites are the reservoirs near Tring in the west of the county. Many of Hertfordshire’s most exciting birds have been found there. The reservoirs are famous for the first British record of breeding Little Ringed Plovers back in 1938 and other ornithological highlights include Britain’s first Marsh Sandpiper in 1887 and England’s first breeding record of Black-necked Grebe in 1918.

In the east of the county is the Lea Valley, (shared with Essex) where some more top sites are located, such as Amwell and Rye House Marsh/Rye Meads. Another site well-deserving of a mention is Tyttenhanger Gravel Pits near St Albans which has, in recent years, proven itself as a place to watch. The county has several RSPB Members Groups, some of which have an online presence.

Top Sites
  • Amwell Gravel Pits

    WebpageSatellite View
    Amwell underwent extensive restoration following the ending of gravel extraction (still going on nearby) and the plans continue. The restoration has produced an excellent quality site for wildlife, not just birds. Otters have been introduced into the area with some success. The site, being part of the Lea Valley, is noted for its wintering wildfowl (including Smew and Goldeneye) but there is also a diversity of breeding species, both waders and passerines included. (Grid reference is for the entrance at the north of the site).
  • Tring Reservoirs

    WebsiteSatellite View
    Tring Reservoirs were the site of England's first breeding Black-necked Grebes (1918) and the UK's first breeding Little Ringed Plovers (1938). They still form one of Hertfordshire's foremost birding sites. They are most noted for good numbers of wintering wildfowl. Recent rarities include Caspian Tern, White-winged Black Tern and Alpine Swift. (Grid reference is for the car park at Wilstone Reservoir)
  • Tyttenhanger Gravel Pits

    WebsiteSatellite View
    Tyttenhanger is another site undergoing restoration following gravel extraction. Recently it has become the county's foremost wader site with Redshank, Lapwing, Little Ringed and Ringed Plover all breeding. Unfortunately there is work going on to flood the area used by these breeding waders and make the area a large fishing lake. However, consideration is being given to wildlife and it is hoped that the site doesn't lose too much of its value. Yellow Wagtails also breed. Nearby fields host good numbers of Lapwing and Golden Plover in winter. This site played host to a drake Lesser Scaup in 1997.

The bird collections were moved out from London in the early 1970s and are housed in part of the original Rothschild complex and in a purpose-built four-storey building. Probably the biggest collection of bird skins in the world.

These are mostly black-headed and lesser black-backed gulls with the occasional, more unusual, Caspian and yellow-legged gulls being spotted by visitors. Many come to Amwell to see not only gadwall and shovelers but also the smew, a rare winter visitor.

Secondly, the land surrounding Royston is intensively farmed. Nevertheless, there is plenty of interest here for the naturalist.
