1919-] Birds of the Canary Islands. 491 



28 August, 1904 (Lanzarote). An adult male shot (Polatzek). Skin 

 examined in Tring- Museum (D. A: B.). 

 2 Sept. 1904 (Lanzarote). An adult female shot (Polatzek). Skin 



examined in Tring Museum (I). A. B.). 

 7 Sept. 1904 (Lanzarote). A tledged young bird Jcilled (Polatzek). 

 20 Sept. 1904 (Lanzarote). Another older young one shot (Polatzek). 

 23 Sept. 1904 (Lauznj-ote). A young female shot (Polatzek). 

 14 Oct. 1904 (Lanzarote). Twelve birds seen together (Polatzek). 

 Doubtless congregating before departure (D. A. B.). 



From March until tlie middle of May no Inrds were 

 observed by Polatzek in 1902. He particularly mentions 

 this, and again that no birds were seen by him during- the 

 montiis of November and December 1904. As Polatzek 

 in addition gives no records for the months of January or 

 February, I take it that he did not observe the bird in ti-.e 

 islands then. 



It is apparent therefore that the Eleonore Falcon is 

 present in the Canaries from mid-May until mid-October, 

 and that it is absent from the Canaries during the winter 

 from mid-October until mid-May. 



Von Tlianner records it as breeding on the Roque del Este 

 (the east rock off the north coast of Lanzarote) and on 

 Montana Clara (Orn. Jahrb. 1913, p. 192), wiiere it is 

 recorded under the vernacular name only — '' Eleonoren- 

 falke.^' 



It is interesting to compare these dates with those fur- 

 nished by Riggenbach, who lived in Mogador over two 

 years. 



During this time he did riot obtain any examples of the 

 Eleonore Falcon between October and the end of April. 

 Specimens from Mogador in the Tring Museum were 

 obtained from the 30th of April until the 15th of October. 



This coincides remarkably closely with what takes place 

 in the Canary Islands. 



Ranye beyond the Archipelago. 



The Eleonore Falcon inhabits the Mediterranean islands, 

 ]Morocco, and Tunisia. It has once been shot in Algeria. 

 It has never been taken in tropical Africa.
