64 Capt. A. W. Boyd on [Ibis, 



Anthus petrosus (? sub-spec). Rock-Pipit. 

 A number about the Canche estuary in October and 

 November. 



Certhia familiaris. Tree-Creeper. 



Only seen rarely in the Touquet woods near Paris Plage, 

 in October and November. 



Regulus regulus. Gold-crest. 



Possibly this was one of the species that had suffered by 

 the 1916-17 winter. Not often seen : three in the Bois de 

 Tailloux, Hamel, on the Somme, 21 INIarch, 1917 ; a few in 

 Rouen, 30 September; common in the Foret d'Hardelot, 

 nqac Boulogne, on 4 November. 



Parus major. Continental Great Titmouse. 



Usually very common — the commonest of the tits. It 

 was one of the birds seen in the trenches among the ruins 

 of Givenchy village in December. 



Parus palustris. Continental Marsh-Titmouse. 



Fairly common in the Bois de Bailleul, near Pont-Remy, 

 March 1917 ; not uncommon in the Le Touquet woods, the 

 Foret d'Hardelot, at Etajjles, etc., in November, and in 

 Adinfer Wood, south of Arras, in March 1918. I did not 

 see anything that appeared to be P. borealis. 



Parus cseruleus. Continental Blue Titmou>e. 

 Fairly common everywhere. 



iEgithalus caudatus roseus. British Long-tailed Tit- 

 mouse. 



On 14 October, two in the Le Touquet woods near Paris 

 Plage with other species of tits. 



Lanius excubitor. Great Grey Shrike. 



On 21 February near Bethune and 25 February at 

 Anneqniti, not far from the first locality ; almost certainly 

 two birds seen at Catelet near Cartigny on 20 April, 1917, 

 were of this species, but I cannot say so definitely.
