6 REPORT ON THE MIGRATION OF BIRDS. 



April. — Thrushes and Blackbirds at K Ronaldshay and Pent- 

 land Skerries, 4th, at latter, and between then and 27th; and 

 Eing Ouzels on 27th, with S.E. fresh on island. 



September. — Most returns from Pentland Skerries of Black- 

 birds and Thrushes ; winds variable, but with easterly ten- 

 dency. Also one record from Noss Head. 



October. — No great appearance ; indeed, as compared with 

 1886, infinitesimal. Only small items on six dates, between 

 10th and 31st, of Redwings (10th), and Blackbirds, Song 

 Thrushes (23d), and Fieldfares (31st) ; winds northerly and 

 easterly. 



November. — The above succeeded by a " perfect rush " of Field- 

 fares at same station on the 1st. "Flocks all day ; " and also of 

 Redwings (several) and two Blackbirds. 2d, Song Thrushes all 

 day. (Winds continuing easterly, but more to south than in 

 October.) Yet after this no great movement apparently at 

 Pentland Skerries. Only other stations recording are Dunnet 

 Head (Fieldfares, strong N.E. breeze, haze ; and Noss Head 

 S.S.E. gale, a few Thrushes) ; and at N. Ronaldshay, Black- 

 birds and Thrushes ; strong K.N.E. and showers. 



December. — Rush all over; only two records at Pentland 

 Skerries of Blackbirds on 21st and 26th. 



Saxicolin^e. — January. — 6th, one " Stonechat " (Wheatear ?), 

 at 1.11 A.M. ; strong S. at K Unst. 



N.B. — This may not have been a Common Wheatear at such 

 a date. 



March. — At Pentland Skerries one Whinchat all day ; 

 moderately W., and showers " rare." 



April. — At Pentland Skerries, 6th, Wheatears (sic) all day 

 on lighthouse; Light N. cloudy; more by the 10th, and one 

 Redstart (or more ?) on 27th. 



May. — " Stonechats" (at N". Ronaldshay) — [probably Wheatears

 Skerries all day on 4th.
