There are several broods of Lapwing and Redshank chick on the marsh, main lake and wader scrape. They are becoming increasingly hard to spot as the tall grasses and herbs grow up around them, giving them better cover from avian predators like Lesser Black-backed Gulls and Carrion Crow. Tufted Duck, Pochard, Mallard, Gadwall and Little Grebe all have nests on the lake islands and amongst the marginal vegetation. Mute Swan broods currently number 5 (with 15 juveniles).
Numbers of Sand Martins and Swifts are high, avidly feeding on increasing midge hatches on the lakes and scrape as the temperatures rise. Smaller numbers of House Martin may be counted, with Swallows being occasional visitors at this time of year (these birds prefer to breed in more rural areas).
Black-headed Gulls and Common Terns are nesting on the rafts on the main lake and reservoir lagoon.
All reedbeds and reed fringes are full of singing Reed Warbler, Sedge Warbler and a few Reed Bunting. Whitethroat, Garden Warbler, Blackcap and Chiffchaff are all breeding amongst the tree/scrub blocks and the hedges around the reserve.
Occasional Yellow Wagtail and Whinchat may be found on the marsh.

Water Voles: best place to see one would be one of the ponds near the Pond Zone building or ‘Down the Plughole’ exhibit. Also the ponds as you enter the wildside area from world wetlands – there’s plenty of feeding activity here.
