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
Buzzards are a spectacular sight, soaring overhead, lapwings swoop over the marshes and hear the distinctive song of Cetti's warblers.
Summer
Summer can be quiet for birds but it is the best time for butterflies, such as meadow browns, marbled whites and common blues. Green woodpeckers may be seen in the grasslands.
Autumn
Early autumn is the time for little egrets and common darter dragonflies. Swallows and house martins feed along the river on their journeys south.
Winter
See flocks of winter waders. Pods of red stinking iris berries. Bright pink spindle berries on the woodland edge.
