distinguishable though it may easily be passed over unless carefully 

 looked at. Usually not shy in my experience, but is stated to 

 be so in Fair Isle by Mr. W. E. Clarke. Flies low, and has rather 

 loud, sharp call-note. Its song is pleasing but slight, but is 

 probably not to be heard in this country. Collett states that it 

 gives its full song only when perched, and when mounting and 

 descending with wa^^ motion in the air it only utters intermittent 

 notes (H.F.W.). 



Breeding -HABITS. — Nests in hollow of ground in peaty soil, 

 sheltered by grass tussock, and often near stone. Nest. — I^oosely 

 built of dry grasses and stalks, lined with down of willow, arctic

 sometimes 3 to 5. Variable, ground greenish- white, thickly freckled 

 fine yellowish-brown spots, paler as a rule than Sky-Lark's, some- 

 times with few bold spots or dark zone and not uncommonly a 

 blackish hair-line. Average of 100 eggs, 22.7 x 16.2 mm. Breeding- 

 season. — From mid-May to Jul}^ in north Europe, often not before 

 June. Incnbation. — Period unknoAvji. Tavo broods reared as a
