Annual passage migrant and summer visitor.

Annual passage migrants and summer visitors at Fairlands Valley Lakes, from where they were first recorded on 6 May 1974 when two were seen. The most seen together there are 11 on 16 September 1980.

Since 1997 between one and seven birds have been seen at Fairlands Valley Lakes throughout the summer. Whilst they are known to travel considerable distances from their nest sites to fish, and this may account for the presence of some of them, others have been seen displaying. The nearest nest sites to Stevenage are at Amwell in the Lea Valley where artificial rafts are provided for them to nest on.

The earliest date they have been seen is 5 April 1982, and the latest date is 23 September 2017, when four juveniles were seen.
