Lastly, of sea birds that may sometimes 
be seen running on the shores of rivers, 
streams and waters (where some remain some- 
times for weeks at a time in autumn and 
winter up to the nesting season in spring 
when they leave for the northern parts of the 
country) there are the Common Sandpiper 
(length 8 inches), the Sanderling (8 inches), 
the Dunlin (7 to 8 inches) and the Dotterel 
(g inches). These are birds somewhat after

the full and jack snipe (see Part II, pp. 53-6). 
The Common Sandpipers, or perhaps the Dun- 
fins, are the ones mostly seen near towns.
