Rare visitor and, uncommon resident.

Prior to 2008 when they began roosting at Southgate House (now known as Vista Tower) in the Town Centre, Peregrines were rare visitors, with two records: one seen flying north near Stevenage on 27 February 2000 and, one seen on 9 January 2007. 

Between 19 September 2008, and 29 January 2009, an escaped juvenile bird, with a jess on one leg roosted regularly on the lettering on the north side of Southgate House in the Town Centre, favoring the letters, “E” and, “O” of, “Southgate”. In 2011 a bird was also seen to roost on the lettering of, “Southgate” from 23 February to 28 March. What appeared to be the same bird (with a tether on its left leg) was seen roosting on the letter, “E” of Southgate from 29 October to 23 November 2011. A male was also seen on the letter, “E” of Southgate on 24 October 2013 and, one was seen over St George’s Way and roosting on the lettering on 6 January 2014.

Between 19 May 2014 and 12 November 2015 birds roosted on the lettering and, roof of Southgate House until renovation works began on the building, with two seen together at intervals from 14 January to 9 May 2015 and, again on 30 October and 8 November 2015. One was seen flying nearby on 3 December 2015 and, one circled around the building on 14 December 2016. These birds may have indicated nesting somewhere in North Hertfordshire.

After Southgate House was renovated and renamed Vista Tower in 2017 and, the pronounced lettering on which the birds had roosted was removed, mostly single birds have been seen roosting on the roof and, on the lighting on the north side of the building with records from every month of the year.  Two were seen mating there on 22 March 2025. The most recent record is one 22 November 2025.
