Fairly common resident.

Foster (1914) recorded Treecreepers as being, “noticed at Stevenage.”

The 1973 Breeding Atlas confirmed breeding from five of the tetrads covering Stevenage, the 1992 Atlas from seven and the 2012 Atlas from one (Broadwater). They suffer in hard winters when there is prolonged ice and snow covering, and this may account for the decline in confirmed breeding between the 1992 and 2012 Atlases. The severe winters of the 1880’s also considerably reduced their numbers.

The 2012 Winter Atlas confirmed their presence from seven of the tetrads covering Stevenage.

They have been recorded from, Abbots Grove, Ashtree Wood, Astonbury Wood, Box Wood, Fairlands Valley Park, Fairview Road, Hertford Road, Lanterns Lane, Monks Wood, New Wood, Aston, Upper Kitching Spring, Ridlins Wood, Watery Grove, Whomerley Wood, Witney Wood and Yeomans Drive, Aston.

Juvenile birds were seen at Norton Green in 2016 and at Fairlands Valley Park in 2020.

There are four unusual records from Stevenage: pair found nesting in a cranny between the timbers of an old barn at Astonbury two feet from the ground on 8 June 1968; 10 seen in a Town Centre Car Park in November 1974; one seen climbing a Church wall in Hydean Way on 3 August 1990; one found dead on a flat roof at Brickdale House in the Town Centre on 23 January 2006.

The Common Bird Census at Watery Grove recorded either their presence during the breeding season or, as holding a single territory annually between 1972 and 1999.
