Brownsea lagoon and wetland
The five hides that overlook Brownsea's lagoon, lakes and reedbed are the perfect perch to watch the spectacular comings and goings of many species of birds.
Reclaimed as pasture in the 1850s, the lagoon was allowed to flood in the 1930s becoming a non-tidal brackish water lagoon offering a sanctuary to a vast number of birds.
From May to July, common and sandwich terns build their nests on specially created gavel islands and cormorants, gulls and waterfowl roost safely, protected from the high tides of Poole Harbour.
In the colder months you can spot over wintering waders stopping off on their migratory journeys to feed in the lagoon. About 15% of the UK's avocet population overwinter here and you may also spot spoonbills and black tailed godwits.
Other resident birds in the lagoon include black headed gulls, oystercatchers, redshanks, herons and Canada geese.
There are two man-made lakes in the central valley of the island and the nearby flooded meadows which have been colonised by reeds, attract a different sort of wildlife. The lakes are surrounded by sallow and alder trees, an important source of seed for over-wintering birds such as siskin and redpoll. You may also see where Sika deer have rubbed their antlers on sallows during the autumn mating season.
The reedbed provides cover for shy wildlife such as the water vole, the water rail and the reed warbler which arrives from Africa in summer and nests in the reeds.
