The Red-necked Grebe is a winter visitor to Tunisia, and is some- 

 times fairly abundant on the Lake of Tunis and other lakes in the 

 north of the Regency, as well as on the more sheltered parts of the 

 sea-coast. 



According to Loche the species is very rare in winter in Algeria, 

 but it seems to be fairly abundant in Marocco, and Favier states 

 that it breeds in that country. This statement is supported bj' 

 Colonel Irby, who writes : " I have seen specimens of the Red- 

 necked Grebe obtained in Marocco by Favier so young that they 

 must have been bred in the country ; and although I was unable to 

 procure a specimen for identification, I am confident I saw several of 

 this species at Ras-Dowra in April. I have no record of its occurrence 

 on the Spanish side" (Orn. Strs. Gib. p. 220). 



This Grebe inhabits the temperate portions of Northern Europe, 

 Asia and America, migrating in winter as far as North Africa, Japan 

 and Pennsylvania. In the Eastern Mediterranean it is rarely to be 

 met with, and throughout a considerable part of that basin it can 

 only be looked upon as of accidental occurrence. 



In its habits and in the localities it affects the present species
