A small number of captive swans were once kept on Swan lake and resulted in "Christmas Bird Count" records from 1979 to 1983. The first record not involving this captive flock was of a single bird seen in the moat near Main Ring Lake from 21-Mar-1993 to 1-Apr-1993. During the spring of 1994 four separate sightings from Lake Law, A.E.Sea, and the Main Ring Lake produced a total of nine individuals. On 24-Nov-2000 a lone individual was seen flying across the site, passing near the high rise and continuing south-west. Since then there have been sporadic records from various lakes on site. From the 15th to the 25th of February, 2004, a pair were present on the Main Injector moats and mating behaviour was observed; a single bird was seen there again in 2005.
