320 STUDIES IN IJUID-MIGRATION 



i^GiALiTis iiiATicoLA, Ringed Plover. — I saw small 

 parties passing south on two occasions — namely, on 

 29th September at 11 a.m., and on i6th October at 

 1.45 A.M. On the latter date they were in rush with 

 other species. 



Vanellus vanellus, Lapivmg. — Frequently ob- 

 served as a spring, autumn, and winter visitor. 



Appears on its way north in spring from 20th 

 February, and continues to pass during March and 

 until mid-April. 



It is recorded as recrossing the Channel during late 

 September and throughout October. 



It occurs in rushes at both seasons along with other 

 species, and during the hours of darkness only. 



The forced winter emigrations, under the stimulus of 

 severe weather, have taken place from 25th November to 

 13th February. On 6th December 1902, some hundreds 

 arrived at 7.15 p.m., and the movement lasted until 

 5.45 a.m. (7th). On the night of the 7th they appeared 

 again at 7.30 p.m., in still larger numbers, and were 

 striking and dropping into the surf in hundreds. The 

 temperature at the time was very low. 



H^MATOPUS OSTRALEGUS, Oyster - Catcher. — There 

 are only two records for the visits of this well-known 

 species. On 27th August 1886 a flock was at the 

 lantern all night, and nine birds struck and were 

 captured; and on 14th November 1887 ^ number 

 were present in a rush from 6 to 9 p.m. 



PiiALAROPUS HYPERBOREUS, Red - uccked Phalarope. 

 — As already mentioned (p. 298), I saw single birds, 

 during the daytime, on 21st September and 8th October 

 — the only records.
