SEPARATE REPORT ON EACH SPECIES. 



Strigid.e. — At Skerry vore, one Brown Owl appeared on 10th 

 May, at '2.30 p.m., in showery weather. 



Falconid.!:. — At Douglas Head, one "Black Hawk" 

 (Sparrowliawk?) was noted at 8 a.m., in clear weather, with 

 light E.X.E. breeze. 



HiRUNDiNiD.E. — The earliest date on which Swallows are 

 recorded from any west coast stations is April 7th, and this at 

 one of our most northerly stations, viz., Butt of Lewis. This is 

 followed by April 17tli at Douglas Head, one of our most 

 southern stations in the Isle of Man ; seen at 12 noon ; wind 

 light S.E. breeze, clear or showers; these were not again 

 observed. Again, on April 24th, their arrival is recorded at 

 Rhinns of Islay. Thereafter none are noted until 6th May, at 

 Loch Ryan, in Wigtownshire, when a flight of fifty was observed, 

 followed by twenty and fifteen on the 8th and lith : winds from 

 N.W. through X. to E. and fresh, clear to haze. At Skerry vore, 

 one was seen on 10th May, in calm, hazy and rainy weather. 

 On 11th, 12th and 13th, eight flew about the Point of Ayr. On 

 24th, four were seen flyintj south past Ardnamurchan station. 

 On 22nd, one at Monach Island ; Avinds from S.W. to N.W., 

 fresh. The remaining records are in June. On June 14th, at 

 Ardnamm-chan, two again seen flying southwards ; and on 22nd, 



\ Light- vessels being only a few feet above the sea, I have not indicated 

 the exact elevation, which, however, is'nsually about 30 feet. 



5 In writing out the data of the spring migration, I take the most 

 southerly stations first, reversing the sequence of the autumn records. 



jl It is noted on the schedule from this -station that the lighthouse, 

 " being inland, little or any observations on the migi'atiou of birds can be 

 noted accurately."
