aware of its annual appearance as a bird of passage in spring. 

 It may be sought with some hope of success from the last two or 

 three days of March till about the middle of May. 



The Grey Wagtail [M. melanope, Pallas) is scarce, but it is to 

 be seen regularly. It is much more common in winter, Mr. 

 Wilson tells me, and he has seen 8 or 9 in the course of an 

 afternoon in October. 



The Blue-headed Yellow Wagtail (M. flava, Linn.) I saw in 

 April, 1898, below Cambuslang on two successive days. It had 

 probably come in the company of its congener the Yellow Wagtail 

 {M. raii (Bonaparte)), which is one of our ornithological dis- 

 tinctions in this part of the country. Of this species a colony 

 comes annually to the river east of Glasgow, where it is a con- 

 spicuous feature till the individuals scatter to the fields for nesting. 

 Fifteen, twenty, or thirty birds may be seen between Farme and 

 Kenmuir in the course of an hour's walk during the spring migra- 

 tion, and in autumn when they congregate for departure a flock 

 estimated to number 250 birds has been recorded by Mr. Wilson. 

 Of this flock about 100 were in the field on the ground, 100 

 perched on cornstalks, while about 50 were shooting out from the 

 shelter of the banks on short fly-catching flights. For eleven 

 consecutive years I have records of its first occurrence (chiefly 

 between Farme and Cambuslang) between the lith and 22nd of 

 April, so that it is a pretty regular comer, but this year none 

 appeared till May. 



The Tree-Pipit {Anthus trivialis (Linn.)) is a regular but 

 not numerous visitor to the sylvan parts of the river above 

 Carmyle. 



The Meadow-Pipit {Anthus pratensis (Linn.)) is a con- 

 spicuous bird of passage in April, and, according to Mr. Wilson, 

 is quite common in winter. Many may be seen from Dalmarnock 

 Bridge upwards in spring, sometimes in flocks up to twenty or 

 more, and in summer a pair or two may still be seen in the fields 

 or waste ground adjacent. It is interesting to realise, when the 

 middle of May is readied, that the passage of the familiar moss- 

 cheeper is over. These changes, from month to month, are a spice 

 to observation.
