Each season brings a different experience at our nature reserves. In spring, the air is filled with birdsong as they compete to establish territories and attract a mate. In summer, look out for young birds making their first venture into the outside world. Autumn brings large movements of migrating birds - some heading south to a warmer climate, others seeking refuge in the UK from the cold Arctic winter. In winter, look out for large flocks of birds gathering to feed, or flying at dusk to form large roosts to keep warm.
Wintering ducks and geese depart for colder climes. Hundreds of displaying wading birds like lapwings, redshanks, curlews and drumming snipe. The first call of the corncrake can be heard in mid-May.
Hunting birds of prey, such as hen harriers and buzzards. Corncrakes calling throughout the night. Otters, common and grey seals.
Barnacle and white-fronted geese return from Greenland. Migrating waders arrive on the floods and estuary. Fieldfares and redwings pass through. Ducks, including wigeons and teals, on the floods.
Hen harriers and peregrines hunting. Wading birds such as dunlins, godwits, oystercatchers, redshanks, ringed plovers and turnstones on the estuary. Hunting barn owls. The buffet of barnacle geese is too good an opportunity to waste for both young golden and white-tailed eagles! Both species can often be seen through the winter, particularly early morning and early evening when the geese are at their roost site on the saltmarsh.
