Corridoo Forest

Chris Sutton reports; Willow Tit seen & heard calling today at the Corridoo at NX68062970. I have recorded them at this end of the forest in August 2020 (2 birds) & Jan 2019 (not visited this spot much since). I suspect there is a small breeding population here. Supporting cast of Coal Tit, Great Tit, Blue Tit, Long-tailed Tit, Goldcrest, Siskin & Chaffinch. But no Crossbill today (usually a good site).
