Christchurch Park is home to in excess of 100 different bird varieties, including a large selection of ducks, geese and swans which inhabit the two large ponds situated within the park. A small bird reserve was set up in the early 1990s, and dog-walkers are restricted to keeping their pets on a lead within this area to reduce disturbances to the birds. Alongside the birds of the park, grey squirrels and a fox inhabit the arboreta.
