32 JOTTINGS ABOUT BIRDS. 



122. THE COMMON SHELDRAKE Tadorna cornuta 

 (S. G. Gmelin), is a winter visitor principally, but 

 a few apparently remain to breed. 



123. THE RUDDY SHELDRAKE Tadorna casarca 

 (Linnaeus), is a common winter visitor to the lakes 

 of Algeria, many, however, breeding in various 

 parts of the country. Hundreds were observed by 

 Canon Tristram on the small sheets of open water 

 near Tuggurt and elsewhere. It breeds in holes in 

 cliffs, often far from water. Taczandwski gives the 

 lakes near Batna as a locality for this species. 



124. THE GAD WALL Anas strepera, Linnaeus, is 

 principally a winter visitor to Algeria, where it 

 frequents the lakes and marshes. A few, however, 

 remain to breed in spring. Taczanowski found 

 it fairly common near the Fezzara Lake and 

 Constantine. 



125. THE PINTAIL DUCK Anas acuta, Linnaeus, 

 is a regular winter visitor to Algeria. 



126. THE WIGEON Anas penelope, Linnaeus, is a 

 very common winter visitor to Algeria, and said by 

 Taczanowski to be met with everywhere on the lakes. 



127. THE TEAL Anas crecca, Linnaeus, is a 

 common winter visitor to Algeria, and, according 

 to Canon Tristram, breeds in the country in small 

 numbers.
