THE BIRDS OF ALGERIA. 23 



hjperboreus (Linnaeus), is an equally rare nomadic 

 winter migrant. 



75. THE SLENDER-BILLED or MEDITERRANEAN 

 CURLEW Numenius tenuirostris, Vieillot, is a resident 

 in Algeria, but its numbers are increased in winter 

 by migrants from South Europe. Taczanowski 

 states that it frequents and is very common at the 

 lakes between Batna and Constantine (Tinsilt and 

 Mzouri). 



76. THE COMMON CURLEW Numenius arquata 

 (Linnaeus), is a widely distributed winter migrant 

 to Algeria. 



77. THE WHIMBREL Numenius phteopus (Linnaeus), 

 occurs on spring and autumn migration in Algeria, 

 but whether any individuals remain to winter in the 

 country I am unable to say. Taczanowski states 

 that it is rarer than the Curlew. 



78. THE OYSTERCATCHER Htematopus ostralegus, 

 Linnaeus, is a winter visitor to the coasts of Algeria. 

 Whether it ever ascends the rivers or visits the 

 inland lakes appears to be unknown. 



79. THE AVOCET Recurvirostra avocetta, Linnaeus, 

 may possibly still continue to breed in Algeria, but it 

 is perhaps best known as a winter visitor, if uncom- 

 mon. Taczanowski only met with this species once. 

 Canon Tristram observed it at Tuggurt in January.
