100 REPORT ON THE MIGRATION OF BIRDS. 
October, considerable numbers of Zurdidw. Earliest record in 
autumn, one Thrush on 1st September at 109, and one Ring 
Ouzel on 15th at 102 (Rhinns of Islay); and latest record 
November 16th [if we except two records on 22d and 23d 
January 1886, which really belong either to local influence, or 
is a beginning of the spring migration of 1886]. Thus the 
migration of Zurdide in 1885 is almost unique amongst our 
records for the shortness, suddenness, and rapidity with which 
it was accomplished, occupying limits strongly defined in time 
by the above dates, viz., in all—leaving out the two solitary 
September records—only from 9th October to 16th November, 
or 38 days. The stations participating in the rush are 93 
(Skerryvore), 94 (Dhuheartach), 101 (Skervuile), 102 (Rhinns 
of Islay), 108 (Lamlash), 109 (Turnberry), 113 (Mull of Gallo- 
way), and 114 (Little Ross). More specialised rushes were :— 
On 17th, of Thrushes and Missel Thrushes at 94, and of Redwings 
at Rhinns of Islay; on 10th and 11th November, of Missel 
Thrushes and Fieldfares, with few Mavises, at 93, 94, and of the 
same species in small numbers, with large numbers of Thrushes, 
Blackbirds, and Redwings, on 9th, 10th, 11th, up to 16th, at all 
stations. Most at 93 and 94, but movement extensive and general 
at all, and suddenly over by the 16th, if we except one solitary 
record of five Mavises on the 21st at (Kyleakin) 90, the only 
record from that station of Zurdide. Prevailing wind strong 
S.8.E. to S.E., and back to S., all these two months; sometimes 
northerly in October, but never for long. 
SAXICOLINZ.—Jn Spring, an extensive migration of Wheatears 
and (or) “Stonechats.” [The name Stonechat is the one almost 
universally used at 93, 94, 101, 102, and 113, but “ Wheatear ” 
—the more correct name for the species intended—is used at 
88 (Fladda) and 114 (Little Ross). The true Stonechat has a 
black head, and is about the same size as a Whinchat, 2.e., much 
smaller than the Wheatear. But the name “Stonechat” is of 
almost universal use in Scotland for the Wheatear—indeed, a 
generally accepted local name.] Earliest record in spring, April 
Ath, at 102 (Rhinns of Islay); latest, 2d June, at 93 (Skerry- 
vore). The general rush took place between the 11th and 20th, 
and appears to have been unusually heavy, such terms being 
used, at all stations, as “numbers all night,” “fifty,” “forty,” 
“ oreat numbers,” “rush all night,” “hundreds all night,” ete.
