28 REPORT ON THE MIGRATION OF RIRDS. 



Crows, but none recorded as accompanying the latter. Only 

 records on two days in September, one day in November, and 

 one day in December. 



In Spring, Hooded Crows (Corvus comix, L.) are reported 

 from Pentland Skerries, Bell Rock, and Isle of May. Earliest, 

 February 23rd, at Pentland Skerries ; latest, May 3rd at Pent- 

 land Skerries. No great rush ; less than usual. Mr. Agnew's 

 note at April 10th, " very few Hooded Crows this year." It is 

 difficult even to fix an indication of a rush. All the records of 

 Hooded Crows and Carrion Crows occur with either fresh S. 

 or light S.E., excerpt a few of the latter, with N.E. clear, 

 on April 15th. Of Carrion Crows, a slightly larger and more 

 compressed migration, beginning on 8th March with twelve 

 seen, ending 15th April; and an indication of a rush between 

 8th and 15th, flying N., recorded only from Bell Rock and Isle 

 of May. 



In autumn, a more decided movement of Hooded Crows, with 

 a few Carrion Crows (the latter on October 24th to 26th), records 

 from Sumburgh Head, N. Ronaldshay, Pentland Skerries, 

 Girdleness, and Isle of May (none noted at Bell Rock). 

 Earliest, at N. Unst (most northerly station) ; on Nov. 7th one 

 got in court with broken wing, and at N. Ronaldshay on 8th, 

 numbers; strong S.W. Next earliest, on 11th at Pentland 

 Skerries, 3 seen. Mod. S., clear. Latest on December 4th at 

 Pentland Skerries, and at Girdleness on January 4th at 

 former, and Dec. 4th at latter (with large flocks of Rooks at 

 the latter). Decided rush between Oct. 11th „ and 26th at 

 Pentland Skerries (14th), Mod. E., and at Isle of May. The 

 numbers recorded are, on 11th and 12th one -shot by J. A. H. B.; 

 no more till 23rd, eighteen flying N. (and Rooks), forty on 24th 

 and forty on 25th, with one Carrion Crow. Continued on 26th ; 

 one lighted on lantern (rare). Again, in November; a number 

 for some days (along with Ravens, at Sumburgh Head on 10th ; 

 also at Pentland Skerries a few, arrd the indication of a rush at 

 Isle of May, on the 12th to 15th, flocks of nine and twelve 

 having been seen on these dates.

 Isle of May, stayed between i6th and 21st, and one seen on 

 25th. None anywhere in March, but resident from -April 1st till 

 August 1st, when all left. Besides these, a few passing birds at
