190 A PRACTICAL HANDBOOK OF BRITISH BIRDS. 



Food. — ^Insects, animal and vegetable matter picked up on shore. 

 Insects taken include coleoptera, diptera and larvse, and aphides. 

 Small worms, Crustacea (sandhoppers), slugs, small marine mollusca, 

 remains of small fish, and seeds also recorded. 



Distribution. — British Isles. — Resident. Generally distributed on 

 rocky shores throughout. Also on many flat shores in autumn and 

 winter. 



Migrations. — British Isles. — Autumn immigration east coast Great 

 Britain, and return-migration spring. There is evidence that 

 some migrants pass on southward. No regular migration noted 

 elsewhere. 



Distribution. — Abroad. — Channel Islands, and coasts of north 

 France. According to Collett {Nyt Mag. Naturv., xxiii, p. 144, 

 XXVI, p. 306) this form breeds on coasts of Norway, while A. 

 spinoletta littoralis is the Baltic form. In winter vagrant, and found 

 along the coasts to Spain, also occasionally inland. 



76. Anthus spinoletta littoralis Brehm*— THE SCANDINA- 

 VIAN ROCK-PIPIT. 



Anthus littoralis Brehm, Handb. Naturg. Vog. Deutschl., p. 331 



(1831— Danish Isles). 



Anthus rupestris, Yarrell, i, p. 588 (in text) ; Saunders, p. 143 (in text). 



Description. — Adult male and female. Winter. — Apparently 

 exactly like A. s. petrosus (see p. 188). Summer. — ^Moult as A. s. 

 petrosus. New feathers of upper-parts are rather greener with 

 more slatish edges and not so brown as A. s. petrosus ; chin more 

 whitish than in A. s. petrosus ; throat and upper-breast with var3dng 

 amount of bufiish-pink ; sometimes the pink is very marked and 

 extends all over throat and breast and in such examples the streaks 

 of breast are usually absent, in other examples the pink is reduced 

 to a tinge on a few feathers of lower throat and there is every 

 variation between these extremes. 



Measurements and structure. — As in A. s. petrosus. 



Breeding-habits. — Similar to those of British race. Nest. — Some- 

 times reindeer hair in lining. Eggs. — Average size of 19, 21.5 x 

 15.4 mm. Breeding-season. — ^From mid-May onward in Norway, 

 in June in high north, where only one brood probably reared. 



Food. — Similar to that of the British race. 



Distribution. — British Isles. — Since Booth noted its occurrence 

 in Sussex in March and April very little recorded. Has been 

 observed in parts of Wales, Scilly Isles, Northumberland, Lines., 



* The name rupfstris refers only in part to this bird. — E.H.
