322 STUDIES IN BIRD-MIGRATION 



AcciPiTER Nisus, Sparrow-Hawk, 

 Ushant. — Single migratory birds were observed on 

 several occasions between loth and i6th September. 



Falco peregrin us, Peregrine Falcon. 

 Ushant. — A pair is resident on the cliffs of the island, 

 and the birds were observed almost daily. 



Alderney. — On 20th September one was noted on 

 the south cliff. 



Falco /ESALon, Merlin. 



Alderney. — One was seen at the west end of the 

 island on 23rd September, doubtless a migrant. 



Falco tinnunculus, Kestrel. 



Ushant. — Migrants were not uncommon, and several 

 were seen daily during our stay on the island — 9th 

 to 17th September. 



Alderney. — Extremely abundant during the last 

 weeks in September. Eight or nine were seen on the 

 wing simultaneously, and a considerable number — a 

 score or two — must have been present on several days. 

 These birds were undoubtedly migrants, and were 

 probably attracted by the abundance of a coleopteron 

 which rejoices in the name of the '* bloody-nosed beetle " 

 {JTimarcha sp.). The late Mr Smith doubted whether 

 the numbers of this bird were at all increased during 

 the migratory season in the Channel Islands. His 

 remark certainly does not apply to Alderney, where 

 we saw a score of different individuals in a few minutes 

 on several occasions. 



Pandion haliaetus, Osprey. 



Ushant. — On the 9th September an Osprey was 

 observed quite close to our steamer, on leaving the 

 island of Molene for Ushant.
