Parus palustris. Marsh-Tit. 



Not imcommon. A iiest with eight fresh eggs on 8 May. 

 It was about six inches down from the crown of a rotten 

 pollarded willow and some six feet from the ground. The 

 nest was very substantial and did not resemble that of a 

 Willow-Tit, though it would, perhaps, have been more satis- 

 factory if identification could have been made even more 

 certain by obtaining a bird, 



Parus caernleus. Continental Blue Tit. 



Common and breeding in suitable holes in the orchards. 



^githalus caudatus. Long-tailed Tit, 



Fairly common up till the end of April, when they dis- 

 appeared. One nest was found suspended in broom in the 

 Foret de Crecy on 3 May with one egg. The nest was 

 unfortunately subsequently deserted owing to rough treat- 

 ment by one of the writer's men.

 First noted on 3 May. A not uncommon breeding species 

 in the hedges bordering railway-lines round Abbeville.

 fairly common and a few nests were found,
