The Richmond Park Bird Recording Group has published a leaflet showing all the birds recorded in the Park between 2001 and 2010, with comments on their frequency, location and so on (download below).

In total 156 species were recorded, of which 62 are thought to have bred. This compares with 206 species recorded since records began in 1921.

Among the rarest are the Long Eared Owl, a pair of which attempted to breed in 2009, the Rough Legged Buzzard, which was photographed over Pen Ponds in 2007, and the Golden and Grey Plovers, which were seen in 2002 and 2008 respectively.

The Peregrine Falcon was seen in 2004 but also regularly in 2008-10, since it now breeds in London. Most breeding birds breed every year but some are irregular such as the Kingfisher and the Pied Wagtail.
