28G THE SCOTTISH NATURALIST 



Pied Wagtail, Motacilla lugubris. 



A few pairs are summer visitors to the subalpine and valley 

 zones It nests annually in the Lodge garden, and occasionally 

 at Loch na Lap at 1940 feet, and also on the banks of the burn 

 running out of that loch at i860 feet both remarkable altitudes 

 for breeding haunts of this species. It is more frequently observed 

 on the lower ground about Loch Treig side. Immigrants, for 

 the summer, have been observed at Loch Ossian (1269 feet) 

 as early as the 2nd of March. 



Grey Wagtail, Motacilla boarula. 



This species seems to be a summer visitor to the valley 

 zone only, where it nests on the margin of Loch Treig at 800 feet, 

 and on its tributary streams up to an altitude of about 1000 feet. 



Tree Pipit, An thus trivialis. 



This is one of the interesting summer visitors which annually 

 seek the Ossian woods. In these it is fairly common, especially 

 among the birches, where it nests up to 1550 feet. 



Meadow Pipit, Anthus pratensis. 



This is the most alpine, wide-ranging, and abundant of the small 

 birds found in the Forest. It occurs, as a summer visitor, from the 

 low ground (700 feet) to the summit of Beinn Eibhinn (361 1 feet), 

 the highest of the Corrour mountains. It is also found on 

 moorland ground, some of which is little more than desolate morass. 

 In 1 91 6 it appeared on Loch Ossian side on the 5th of April. 



Tree-Creeper, Certhia familiaris. 



British Race, C. familiaris britannica. 



Not uncommon, and resident in the birch wood, where it ranges 

 and nests up to at least 1550 feet. It has not been observed else- 

 where in the Forest. 



Great Titmouse, Paras major. 



British Race, P. major newtoni. 



Judged by its numbers, this is one of the rarest of the Forest 

 birds. It is probably only a recent colonist at Corrour, for its 

 presence was not detected there until December 1915, when a pair 

 was observed in the birch wood feeding on the seeds or insects
