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



females 270-305) of S. a. aluco. In colour one of those 

 from Portugal is very black and grey (a type which is very 

 rare indeed in Grreat Britain), throe others are rather browner, 

 and two are rufous. Of the Cantabrian birds one is rufous 

 and the other grey-brown. 



fFalco tinnunculus. 



Kestrels were fairly common, but except for these and 

 (/ommon Buzzards, Hawks were very scarce. A large 

 Falcon seen in the distance above some rocky hills near 

 Potes was probably a Peregrine. 



Buteo bu1;eo buteo (L.). 



Common Buzzards were fairly plentiful especially at Panes, 

 but we did not identify any Honey-Buzzards, which Irby 

 found common in summer in the Potes district. An adult 

 male B. b. buteo, which I shot, has a considerable amount of 

 rufous on the tail, and the wing measures 375 mm. 



Accipiter nisus nisus (L.). 



We saw two or three Sparrow-Hawks at Riaiio and at 

 Potes, but they seemed to be very scarce. An adult female, 

 which I shot at Riano, has the upper-parts very dark grey 

 without a tinge of brown, while the under-parts have close 

 and very dark bars. 



tMilvns milvus. 

 We saw only one Red Kite (at RiaHo) and no Black Kites. 



fCiconia ciconia. 



There is a single Stork^s nest at Riano, but the birds had 

 left before we arrived. 



tColumba palumbus. 

 We saw a few Wood-Pigeons and were told that they were 

 very numerous in some autumns. 



fVanellus vanellus. 

 Two Lapwings at Riano on 27 September were the only 

 ones we saw.
