1918.] Letters, Extracts, and Notes. 1^ 



lynx torquilla. Wryneck. 



A nest containing newly-hatched young, in a hole low 

 down in a pollarded willow near Bercq-sur-Mer on 25 June. 



Phcenicurus titys. Black Redstart. 



Several pairs nest among the buildings in Montreuil, and 

 a male was seen and heard singing in June on a house-top 

 in Paris-Plage. 



Phylloscopus sibilatrix. Wood- Warbler. 

 A male in full song in a beech-forest near Montreuil in

Upupa epops. Hoopoe. 



A pair successfully hatched out a brood in a hole in a 

 walnut-tree situated in the immediate vicinity of Montreuil. 



Willow-Tit. ? subspecies. 



A nest with nine eggs on the point oi hatching on 

 19 May. Swamp bordering River Canche, Montreuil. 

 The nesting-hole was about five feet up in an extremely

 hbre and a few minute pieces of wool. 



Hypolais icterina. Icteriue Warbler. 



Quite common in all sorts of undergrowth. Nests found 

 in alder, willow, hawthorn, syringa, bramble, dogwood, and 

 elderberry. I have no doubt this species nests in tlie Somme 

 valley, and that I overlooked it last year owing to my hunting 

 for it in marshes instead of in gardens, young plantations, 

 etc, which it favours largely to the exclusion of marshy 

 localities. 



Pyrrhula? Bullfinch. 



A nest with five fresh eggs on 30 June in an alder. Several 

 pairs irequeiit the marshy spinneys of the River Canche 

 valley, in the vicinity of Montreuil. 



In conclusion, I should like to add that the Marsh- 

 Warbler {Acrocephalus palustris) which I found common 

 last year in the Somme valley is even more common in the
