123. Phylloscopus collybita collybita (Vieill.) — THE CHIFF- 

 CHAFF. 



Sylvia collybita Vieillot, Nouv. Diet. d'Hist. Nat., nouv. ed., xi, 

 p. 235 (1817— France). 



Phylloscopus collybita (Vieillot), Yarrell, i, p. 437 ; Phylloscopus rufus 

 (Bechstein), Saunders, p. 67. 



Description (Plate 11.) — Adult male and female. Winter. — 

 Whole upper-parts varying from brownish olive-green to brown 

 tinged with olive-green (rump usually slightly more greenish 

 than rest of upper-j)arts) ; lores blackish, feathers tipped huffish, 



* The name " rufus " has been erroneously used for the Chiffchaff. It 

 was first introduced by Gmelin, but his Motacilla rufa does not refer to a 

 Phylloscopus at all. The first certain name is collyhita. — E.H.
