There was therefore in 1906 a plentiful supply of food for 

 the birds, while in 1907 they had almost none. Along with 

 that fact, we have also to take into consideration the climatic- 

 conditions which prevailed during the winter season. The 

 weather in 1906 was more severe than in 1907, and was 

 notable for keen frosts and severe snowstorms, as compared 

 with the continuous rains and open boisterous weather which 

 prevailed during the latter season. Last winter the Missel 

 Thrush, Redwing, and Fieldfare merely put in an appearance 

 and went elsewhere, owing to the mildness and openness of the 

 weather and the scarcity of food. 



At different times, through stress of weather, many birds 

 were driven into the park for food and shelter. This enabled 

 me to add to the list a few which otherwise might never have 

 been noted. 



Missel Thrush (Turdus viscivorus). — About the middle of 

 November, 1906, during keen frost, a flock of about a dozen 

 Missel Thrushes visited the park, but they began to dwindle 

 off as the weather became more open. The Missel Thrush 

 could be seen daily up till the breeding season. By the end 

 of March, 1907, all had left, and they did not make a 

 reappearance till 13th September. An occasional bird was 

 seen during the next few weeks, when they again left the park. 

 A pair made a reappearance on 11th January, 1908. Since 

 then thev have been seen almost daily. On 25th March a 

 second pair were seen about the south end. 



Song Thrush (Turdus musicus). — Common all the year 

 round. This year the Song Thrush started to sing as early 

 as 23rd January, probably owing to the mildness of the 

 weather. In April, 1907, I watched a pair of birds carrying 

 building material, but was unable to locate the site of the 

 nest. After a while the birds were seen carrying food for 

 their young ones; and on 6th May a pretty sight could be 

 observed near the gardener's house, as the old birds were then 

 teaching their four young ones to fare for themselves. During 

 the first week in December, 1907, the weather was very stormy, 

 and a large number of Song Thrushes came into the park for 

 a few days.
