532 Lieut. J. N. Kennedy on [Ibis, 



Galerida cristata. Crested Lark. 



During November several small companies were seen near 

 our battery position at Martinsart, and their musical calls 

 were frequently heard in the early mornings. 



Motacilla lugubris. Pied Wagtail. 



A few frequented the marsh below Autlmille during the 

 frosty weather in January. 



Motacilla boarula. Grey Wagtail. 



Commoner than the Pied Wagtail, and seen in the 

 marshes throughout the winter. 



Anthus pratensis. Meadow-Pipit. 



This species occurred, but not in great numbers, in the 

 neighbourhood of Martinsart. Small companies came down 

 to the marshes at Hamel during the hard weather in 

 January. On 26 February a few were seen near Beau- 

 court. 



CertMa familiaris (subsp. ?) . Tree-Creeper. 

 Only once encountered in a deserted garden of Authuille 

 on 4 November. 



Regulus regulus. 



This species was not observed except in December and 

 January, when small companies were seen in Aveluy Wood 

 and among the trees near the river at Hamel. 



Parus major. Continental Great Titmouse. 



This was the commonest of the Tits. It became very 

 numerous in the marshes near Hamel in January. On the 

 2nd of November two Great Tits were exploring the Ijroken 

 tree-stumps which are now the only indication of the site 

 of Thiepval. Occasional 77 mm. shells were bursting near 

 the birds, in spite of which they continued their quest 

 unperturbed. 



Parus ater. Continental Coal Titmouse. 

 Not common ; occasionally seen near Mailley-Maillet, 

 Hamel, and Authuille.
