THE BIRDS OF ALGERIA. 65 



285. THE BLUE-HEADED WAGTAIL Motacillajlava^ 

 Linnaeus, is a winter visitor to Algeria. I met 

 with it in flocks in the oases, apparently on migra-

 observed it between Constantine and Batna, much 

 further north, in March. 



286. THE COMMON WREN Troglodytes parvulus, 

 Koch, is a resident in Algeria. I found it gener- 

 ally distributed throughout the Djebel Aures. 

 One example I shot is slightly paler than specimens 

 from Europe. 



287. THE COMMON CREEPER Certhia familiaris, 

 Linnasus, is a resident in Algeria. It frequents 

 the pine and cedar forests. Taczanowski states 

 that it is paler than the Creeper of Europe. I met 

 with this species in the cedar forests west of Batna. 



288. THE NUTHATCH Sitta c&$ia, Wolf, is a 

 resident in Algeria. Whether it differs from typical 

 European examples I am unable to say, never 

 having seen a specimen from the country. 



289. THE GREAT TITMOUSE Parus ?najor, Lin-

 Algeria north of the Atlas.

 fined to the mountain forests. I obtained seven
