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.
Spring
Lapwings tumble in excitable displays over the nesting areas. Early morning is the best time to see the hares 'boxing'. Watch out for the first wheatears and swallows to arrive from Africa.
The flood-waters are retreating, leaving muddy edges - look out for migrating waders like common sandpipers and ruffs. There are still large numbers of wigeons, teals, black-tailed godwits and other water birds biding their time or passing through on their way north.
Summer
Redshanks and avocets scold you from a distance as they watch over their chicks. The grass is peppered with the colours of wildflowers. Wall brown and common blue butterflies are found along the paths on warm, sunny days. Grey herons stalk the ditches. Summering black-tailed godwits can be found in the wetter spots.
Autumn
A dashing falcon at this time of year could be a merlin just in from Iceland. Look for skeins of pink-footed geese flying to and from their roost out on the mudflats at dusk and dawn. Migrant hawker dragonflies patrol the ditches on sunny days. Wigeon and teal numbers begin to build up.
Winter
You will be sure to see huge flocks of wigeons, teals, lapwings and golden plovers wheeling and turning over the marshes. Look out for the bird of prey that has caused the panic. It could be a kestrel, merlin, peregrine or sparrowhawk or perhaps one of the voracious great black-backed gulls that patrol these marshes.
