No. 117. DOTTEREL. (iMiiliomias niorinellus.) 



This Plover is a migrant to the British Islands in late spring and 

 autumn, but a few pairs remain to breed on some of the mountain-tops 

 of Seotland and of the Lake District. The nest is a mere hollow in the 

 moss covering some elevated plateau, where the vegetation consists 

 chiefly of deer-grass and dwarf alpine plants. Patches of the little ])ink 

 flower I'^ileiw ucaulis (some nearly a square yard in extent) abounded in 

 the proximity of the uest exhibited, and contrasted strikingly in colour 

 with the otherwise sombre surroundings. The eggs, three in nundjer, 

 are yellowish olive heavily blotched and spotted with brownish-black ; 

 they are laid early in June, and arc rennirkably difficult to find, owing 

 to the fact that the parent, if sitting, will allow itself to be almost 

 trodden on before it leaves the nest.

(StercoraiiiLs crepidatus.) 



This eircumpolar species, most common on the northern and eastern 

 coasts of Great Britain, breeds in the north of Scotland and has nume- 

 rous colonies on the Shetlands, Oi'kncys, and Outer Hcl)rides. it feeds 

 principally on fish, obtained by robbing the smaller (lulls and Terns ; 

 but is also said to prey on wounded birds and on the eggs of other sea- 

 fowl. Two brownish-green eggs, blotched with dark brown, are laid 

 in a hollow iu the moss or grass of the open moorland in the vicinity 

 of the coast. 



Two distinct phases of plumage occur, one being entirely sooty, while 

 the other has light under-parts : in the pairs exhibited, tlie light-coloured 

 specimen is a male.
