1921 .] Bird-Migration by the Marking Method. 
(Case 432) was recovered about fifteen miles distant in a 
north-easterly direction (Glenlyon). Three others marked 
as chicks in Scotland were shot in their first season near the 
place where they were marked. One (Case 857) marked as 
a chick at Benarty Hill, Fifeshire, on 31 May, 1913, was 
caught in snares at Forgandenny, Perthshire, on 6 August, 
1915, a distance of fourteen miles. 
PARTRIDGE (Perdix perdix Linn.). 
Fifteen marked in Scotland, all as hand-reared or imported 
birds, were recovered at the places where they were marked. 
Of these, twelve records can be grouped as follows :— 
Birds imported from Hungary and turned down in Perthshire on 
14 or 15 February, 1913: recovered on 12.9.13 and 18.9.13 
(two), and about 13.10.13 (two), 13.11.13,31.1.14, and 28.12.16 
respectively. 
Birds imported from Bohemia and turned down in Aberdeenshire 
on 30 November, 1910: recovered during the same winter, in 
April 1911, on 28.9.11, and on 14.10.13 respectively. 
OTHER RECORDS. 
There are also records for the following species :—Jackdaw 
and Pheasant, three each ; Yellowhammer and Wren, two 
each ; Bullfinch, Coal-Titmouse, Bedwing, Willow-Warbler, 
Long-eared Owl, Cormorant, and Coot, one each. Little or 
no interest attaches to any of these cases. 
XI.—CONCLUSIONS REGARDING BIRD-MIGRATION. 
Specific Conclusions .—A number of conclusions have been 
reached affecting the status of various species as migrants in 
the British area. These have already been expressed in the 
preceding sections, and any detailed recapitulation would be 
superfluous. 
Return of Migrants to the same Summer-Quarters .—The 
Swallow, the Spotted Flycatcher, and the Swift have 
afforded definite instances of this fact, previously shown in 
certain other cases and for long presumed on general grounds. 
Other records of birds recovered at the places of marking in 
subsequent summers are invalidated by lack of grounds for
