This is a Rare Visitor to the islands. 



Webb and Berthelot give it as an inhabitant of Tenerife 

 (Orn. Canarienne, p. 8). When recording this species they 

 particularly remark the absence o£ C aruglnGsus, which 

 Ledru is stated to have found in Tenerife in 1810. They are 

 all the more likely to liave been sure of their identification 

 of Montagu's Harrier before including it in their list. 



Bolle mentions it (J. f. O. 1854., p. 450). 



Cabrera says (Catalogo, p. 33) that it is an accidental 

 migrant in the spring, and this observation is quoted by 

 Polatzek (Orn. Jahrb. 1909, p. 119). 



The only specimen which I helieve to have been procured 

 was shot in Tenerife by von Thanner in the month of 

 February, and recorded in the Ornithologische Jahrbuch, 



1903, p. 176 by Tschusi, and by Thanner in Nov. Zool. xi. 



1904, p. 431. The year in which it was obtained was not 

 then mentioned, but it appears to have been shot in 1903, 

 as Thanner notes having procured the bird in the " pre- 

 ceding year" and is writing in 1904. Also he remarks 

 that it was shot " on the same morning " as Saxicola deserti. 

 Three of the latter birds shot by Thanner are examples of 

 (Enanthe deserti homochroa and are in the Tring Museum ; 

 they bear on the labels the dates 24/25 Feb. 1903. 



Early writers record it under the name F. cineraceus. 



Range. Montagu's Harrier breeds in Europe, also in 

 Morocco and Algeria. In winter it ranges to Cape 

 Colony. 



Buteo buteo insularum *. Little Insular Buzzard. 

 Buteo insularum Floericke, Mitteil. osterr. Reichsb. iii. 

 1903, p. 64 — Type locality : Grau Canaria. 

 A Resident subspecies. 



* The supposed occurrence of Buteo buteo buteo in the Canaries on 

 migration (Ibis, 1893, p. 196) cannot be maintained, the bird in question 

 being an example of the island Buzzard ; it is a female with a wing- 

 measurement of 374 mm. Local migration of the insular form B. b. 

 insularum may take place between the islands, but not from the 

 continent. The possibility of birds having come from the Azores, 

 though unlikely, should not be overlooked.
