340 Mr. H. F. Witherby on a Collecting [Ibis, 



though inclined to be rather dark. Irby states that the 

 species is common and breeds. Chapman and Buck found it 

 singing in the Sierra de Gredos in mid-May, which points to 

 its nesting in that district. 



Turdus merula merula L, 



Blackbirds were common. These, as well as a series from 

 Portugal, I cannot distinguish from the typical form. 



1 Monticola solitarius. 

 We saw a Blue Rock-Thrush in a defile between Riano 

 and Cangas de Onis, but they were certainly not common in 

 the district. 



(Enanthe cenanthe cenanthe (L.). 



The only Wheatears we saw were a few of the common 

 species. 



Saxicola ruljetra rubetra (L.). 



Saxicola torquata rubicola (L.). 



Whinchats were decidedly scnrce and Stonechats not very 

 common. Three of the latter obtained are, I consider, 

 rubicola ; they are rather darker on the upper-parts than is 

 often the case in tbis form, but still not so dark and rufous 

 as the British form, which also inhabits Portugal. 



Phoenicurus phoenicurus. 



Ph. ochrurus gibraltariensis (Gm.). 



We saw a very few Common Redstarts at Riaiio only, and 

 I think that most had migrated as Irby considered them 

 common. The only bird obtained had the 2nd primary in 

 one of its wings broken off and in the other growing, so that 

 it was impossible to say if its wing-formula was like that of 

 Ph. ph. algeriensis, which we had found to Lo the case in two 

 breeding birds collected in Portugal in the summer of 1920. 



The Black Redstart was often to be seen amongst buildings, 

 and was very common on the higher rocky ground, especially 

 about Riaiio.
