Essex - River Lee Country Park

Summary

We will aim to explore the southern half of the reserve in the morning, coming back to the Wildlife Discovery Centre for a picnic lunch and use of the nearby facilities. In the afternoon we will do a loop of the northern half, thus ensuring we cover all the park habitats giving us the largest selection of species. The walk will conclude back at the car park at around 5pm, with a total length of around 4 miles on level, easy going paths and tracks with occasional muddy patches.

Please see below for details on specific species seen in each season.

In Spring

Spring is a good time to see wading birds such as Redshank and Little Ringed Plover, who come to breed here. Common Tern can often be seen feeding on the lake at Fisher’s Green, and Oystercatcher can be seen (and heard!) in this area. Great Crested Grebe and divers are out on the water carrying out their wonderful breeding displays. Barn Swallow, Sand and House Martin swoop around the lakes after their arduous migration journey. Look for signs of Water Vole, such as piles of neatly cut grass stems and latrines on ditches. Woodpeckers drum in the hopes of finding a mate. Wildflower meadows burst into life towards the end of Spring, and Bee Orchids and Ragged Robin can be found here in amongst other wildflowers. Butterflies such as Painted lady and Small Copper are possible here. The blooming of the Cuckooflower and the first call of Cuckoo coincide at this time of year, as the name suggests.

In Summer

The first summer migrants will have already arrived in April and by May the area will be alive with breeding and singing birds, including Reed and Sedge Warbler. Common Tern and Black-headed Gull colonies rest on rafts on the lake in front of the Tern Hide. Fantastic views of Kingfishers can be had at the Kingfisher Hide as they carry food to their young. 30+ pairs of Grey Heron breed in the valley most years, and the Little Egret pairs are close behind with 20-30 pairs. Flocks of Lapwing can be seen over the shallow pools. In the grasslands, the reeling call of the Grasshopper Warbler can be heard, and Reed Bunting, Sedge, and Cetti’s Warbler, can be found. Plus, Common and Lesser Whitethroat, Nightingale, and the occasional Spotted Flycatcher. Hobby are also regularly seen hunting dragonflies on the wetlands, and Barn Owl and Kestrel over the long grass.

In Autumn

The valley is a great place to witness large numbers of birds during their migration, including more unusual birds taking a much needed pit-stop. More notable species include Wood Sandpiper, Ruff and Black-tailed Godwit. The muddy margins host waders aplenty as the water levels drop. Migrating summer guests such as Whinchat and Wheatear can often be seen over fields and meadows.

In Winter

The Lee Valley is an internationally important site for wintering wildfowl. The lakes and lagoons support large numbers of species each year, such as Gadwall, Shoveller, Pochard, Teal, and Smew are possible here. The elusive Bittern and Water Rail can be found nestled in the reedbeds, and Snipe and Jack Snipe feed amongst the rushes. Common and Green Sandpiper can sometimes be seen along the edges of the lake too. Quinoa and Millet are grown in the nearby farmland, and this provides an excellent food source for birds like Yellowhammer and Linnet throughout the winter. These areas are also a good place to spot winter thrushes like Redwing and Fieldfare.
