Buteo buteo lanzarotece Polatzek, Orn. Jahrb. ]903, 

 p. 113. 



The Buzzard from the eastern Canary Islands lias been 

 distinguished by Polatzek as B. h. lanzarotecR. I have not 

 myself compared a large series of adult birds from the 

 eastern and Avestern groups of the Canary Archipelago. 

 Dr. Hartert, who has recently reviewed the Palsearctic forms, 

 tells me that he does not consider the Buzzard found in the 

 eastern Canary Islands can be separated from Buteo b. 

 insularwn, the race inhabiting the western islands. 



The Buzzard is an exceedingly rare bird in Fuerteventura 

 judging from my own experience, for in the course of the 

 entire journey through this island it was only seen on one 

 occasion — in a barranco between La Peiia and Santa Maria 

 de Betancuria. Both Polatzek and von Thanner found it 

 scarce in Fuerteventura. In traversing Lanzarote from the 

 south to the extreme north (see Map of Route, Part I. 

 Plate II.) I did not meet with it until I reached the valley 

 of Haria, where, however, one or two pairs were constantly 

 in sight during the five days spent there. 



The little island of Graciosa is now quite forsaken by the 

 Buzzards, which Meade- Waldo found there in April, 1890. 

 None were discovered on Montana Clara, but on Allegranza 

 it is interesting to note that three or four were seen in one 

 crater, being doubtless resident in the island. 



An immature example was procured in Allegranza. 



Bill black, cere greenish yellow ; iris light hazel ; feet 

 yellow.
