Sevenoaks Wildlife Reserve is the first example of a gravel pit site in the UK being developed for nature conservation. It lies immediately north of Sevenoaks in Kent and covers 73 ha of wetlands. Over two thousand species have been identified at the reserve, which is made up of five main lakes and a mix of ponds, flooded pools, reedbeds, and woodland. The water levels in the lakes are managed so that, in spring and summer, specially created islands and shallows are exposed. This creates feeding and nesting areas for a variety of waders and waterfowl such as moorhens, comorants, coots, and great crested grebes. The winter months see wildfowl such as greylag geese and tufted ducks regularly using the open water on the lakes.
There are numerous bird hides throughout the reserve, which are all free to use and located next to the walking trails. As you walk through the reserve you can also look out for woodland birds such as woodpeckers, parakeets, redwings and jays. As well as kingfishers darting into the water in a flash of blue!
Average rating: 3.2 (good)
Average cost: free!
Best time to visit: all year round, with wildfowl species being abundant in winter. The reserve and nature trails are open daily, from dawn until dusk.

WILDLIFE IN sevenoaks
According to reports submitted to WildSide, the most popular species that can be seen here are:
Great Crested Grebe – 92% OF WildSide Users (12/13) REPORTED SIGHTINGS
The great crested grebe is an elegant waterbird with distinctive chestnut and black head plumes (in summer) which are raised during courtship. During this courtship display, they rise out of the water and shake their heads. Young grebes, which are striped black and white (like humbugs!), are often seen riding on their parents’ backs. Grebes are known to readily adopt flooded gravel workings and move to large lakes and reservoirs in the autumn. Making the reserve a perfect place to spot them.
Greylag Goose – 77% OF WildSide Users (10/13) REPORTED SIGHTINGS
The greylag goose, which is the ancestor of most domestic geese, is the largest of the geese native to the UK. Flocks are typically found around gravel pits and lakes, like those at the reserve. They are often seen alongside Canada geese – which are also found in abundance here. Greylags are a greyish-brown colour with pink legs, and their large bills are orange with white tips. As with most geese, they can often be seen flying in “V’s” above the reserve.
Kingfisher – 0% OF WildSide Users (0/13) REPORTED SIGHTINGS
Kingfishers are typically found near slow-moving water, such as the lakes and ponds at the reserve. They are known for their bright blue and orange feathers, and are around the size of house sparrows with large heads and dagger-like bills. There is a kingfisher hide at the reserve where you can look out for them. However, they can be difficult to spot, even with their bright colours. Listen out for their distinctive call (a shrill “chreee” or “chee-kee”) which usually provides the best clue to their presence.
Redwing – 46% OF WildSide Users (6/13) REPORTED SIGHTINGS
Redwings are winter migrants to the UK, although there are a handful of pairs that nest here. They arrive from September onwards, leaving again in March and April. Redwings look similar to song thrushes, but have a creamy strip above their eyes and red-orange patches on their wings (hence the name!). You can usually see them feeding in fields and hedgerows in open countryside, and they can sometimes be found with flocks of fieldfares. Look out for them in the hedgerows and trees that line the entrance to the reserve, and you may get lucky!
Eurasian jay – 38% of wildside users (5/13) reported sightings
Jays are beautifully coloured members of the crow family. They are easily recognised by the brilliant blue feathers on their wings. You can find them on the reserve year-round, although for much of the year they can be hard to spot. Unlike crows and magpies, they are shy birds. So look out for a flash of white and blue and a screaming call as they fly between the trees. The best time to spot them is autumn when they move about the trees looking for food. During this time they are easy to spot hunting for acorns which they store in their favourite hiding places to provide a source of food for the winter.
Great cormorant – 92% OF WildSide Users (12/13) REPORTED SIGHTINGS
Great cormorants are usually found around the UK’s rocky coastline, but are becoming more common on lakes and rivers inland, especially in winter. If you want to see them at the reserve, they can sometimes be found on the West Lake. However, they are more regularly seen in larger numbers on the East Lake, in front of the Tyler Hide. They are around the size of a goose with large bodies and long thick necks. Adults are black, with white on their faces and thighs, while juveniles are usually dark brown with pale underparts.
GREAT SPOTTED WOODPECKER – 8% OF WILDSIDE USERS (1/13) REPORTED SIGHTINGS
Great spotted woodpeckers are beautiful black and white birds with a shock of red on their bellies. The males also have bright red necks. They can be seen on the trunks of large, old trees in the reserve looking for grubs. Despite their striking colours, woodpeckers can be difficult to spot among the leaves. One way to find them is to stand still and listen out for their distinctive call – a loud ‘click’ or ‘tchick’ sound. You can also listen out for the incredible drumming sound which they make as they peck holes in trees.
RING NECKED PARAKEET – 15% OF WILDSIDE USERS (2/18) REPORTED SIGHTINGS
Another bird that you’re likely to hear before you see is the ring necked parakeet. These are noisy, raucous, squawking creatures. And they aren’t shy! Chances are you’ll see or hear these colourful characters at some point in the reserve. They are called ‘ring necks’ because the adults have a dark circle around the backs of their necks. They are perfectly at home in the wood as there are lots of old trees with holes to nest in. There are various stories about how parakeets ended up in England, but they seem to quite like it here, even though their native range is tropical!
