Rostherne when Tatton was frozen and consorted with a 

 Goldeneye. 



Although the 

 Phalacrocorax carbo carbo (Linnaeus). Cormorant is 



a not infrequent 

 visitor to some of the inland waters it has seldom been 

 noticed on Rostherne. On September 17th, 1908, Mr. 

 Boyd saw a couple of birds near the mouth of the stream, 

 and shortly afterwards they followed fish into a strike 

 net and were killed. They are in the possession of 

 Mr. Egerton. On May 6th, 1914, there was a young bird 



on the water. 



Towards 

 Phalacrocorax graculus graculns (Linnaeus), the end of 



January, 

 191 2, there was an extraordinary incursion of Shags to 

 inland localities in Cheshire, Derbyshire, Yorkshire and 

 Worcestershire.'^ The birds were not driven in by any 

 local bad weather. Two immature birds reached Ros- 

 therne, and were either starved or frozen ; we did not see 

 either alive, but found their bodies in February and March. 



The Great 

 Colyinbus cristatus cristatus Linnaeus. Crested Grebe 



is a common 

 resident on Rostherne, and except when the waters are 

 frozen there are always some birds to be seen. The 

 numbers, however, fluctuate not only at different seasons 

 but in different years ; at times the birds appear to rear 

 most of their young, but in other years very few are got 

 off. Pairing and display is most noticeable in February 

 and March, but occasionally pairs may be seen displaying 

 in November and December. The eggs are usually laid 

 in May, but occasionally in April, and young of various
