(Case 432) was recovered about fifteen miles distant in a 

 north-easterly direction (Glenljon), 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 Benarfcy Hill, Fifeshiro, 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 bo 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 aiid turned down in Aberdeensliire 

 on 30 November, 1910: recovered during the same winter, in 

 April 1911, on 28.9.11, and on 14.10.13 respectively. 



OTHEE EECOEDS. 

 There are also records for the following species : — Jackdaw 

 and Pheasant, three each ; Yellowhammer and Wren, two 

 each ; Bullfinch, Coal-Titmouse, Iledwing, Willow- War bier, 

 Long-eared Owl, Cormorant, and Coot, one each. Little or 

 no interest attaches to any of these cases. 



XL -CONCLUSIONS EEGARDING BIRD-MIGRATION. 



Speci/ir, 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 ihe 

 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
