Adult female Two-barred Crossbill, Lynford Arboretum, Norfolk, late July 2013 (David Campbell)
With reports of up to 50,000 crossbills irrupting from West Siberian forests and vast numbers entering Scandinavia since late June, the UK is set for a bonanza of this trumpet-blowing finch. Already birders are reaping the benefits as following Saturday's arrival of seven individuals (two at Havergate Island and Holme NOA and singles at Gramborough Hill, Cley Beach and Spurn Point), more have been appearing this week with up to 4 (adult female and 3 juveniles) at Lynford Arboretum and a confiding juvenile on Kelling Heath.
