Northern Long-tailed Tits and Luddenham Dean, West Yorkshire, revisited

February 7, 2012:
Another visit today appeared unfruitful until I managed two separate sightings of a Northern in mid-afternoon. The first bird, strikingly prominent with its white head and underparts, appeared suddenly in a flock of about eight of the normal race and rapidly foraged amongst the branches of a leafless tree in search of insects. A little later, a second (or perhaps the same) bird appeared. Recently, one with a shortened tail had been seen here but both today's were normal indicating that at least two of the Northerns are still in the area. As the mist swept up this remote valley in late afternoon, I withdrew, satisfied.
