People have been keenly observing bird life in The Regent's Park since the middle of the 19th century. The Regent's Park boasts an impressive list of at least 200 species.
The Regent's Park's diverse grassland, woodland and wetland habitats together support 21 species of butterfly and more than 230 species of moth.
The Regent's Park is one of the few sites in central London where the Hedgehog is still found. Other mammals include the Fox, Brown Rat, House Mouse, grey squirrel, bats and Woodmouse.
There are many wildlife conservation projects being carried out in the park including the creation of loggeries and 'dead hedges' within woodland areas and the planting and management of reed bed areas.
The Regent's Park's ornamental waterfowl collection was started in the 1930s and was expanded, particularly during the 1970s and 80s, to exceed ninety species of swans, geese and ducks.
