This bird conveniently favoured some trees in front of the offices of Nene Park Trust along Ham Lane near the entrance to Ferry Meadows Country Park west of Peterborough.
A remarkable late date for this species - the latest for Cambs. There have been two overwintering birds, one of these was in the PBC area at Bainton from Jan-Apr 1991 and resembled the Siberian form
blythi. The Ham Lane bird does not appear to be of the usual nominate
curruca form either: it appears too brown-toned above, has a weak face mask, rather sullied underparts and the grey head does not contrast very strongly with the upperparts. It may also be rather short-winged and has rather pale outer tail feathers. It is possibly the
halimodendri form but would perhaps need to be examined in the hand to be sure
