  In reply to LesleyL:

  My edition of Collins (BTO guide to BB) says
  
  Willow
  "...primary feathers project further,relative to exposed length of tertials (primary projection is equal to exposed tertials).
  
  Chiffchaff
  "Has a shorter primary projection than Willow Warbler (equal to two-thirds of exposed tertials).
  
  Perhaps somebody should have asked it for quick verbal rendition,

  1st winter Willow Warbler for me.
  
  Slim, “willowy” shape; all-yellow underparts; prominent dark stripe through eye contrasting nicely with bright eyebrow stripe, grey ring under eye with paler interior, fairly substantial bill with much yellow on lower mandible. Primary projection maybe a bit short and legs dark for WW but neither bothers me.
