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



Niiinenius arquata. Curlew. 



Common in the Canche estuary in October and November, 

 and at the end of July 1918 ; there was a considerable 

 increase at the end of October, and several hundreds were 

 daily about in the salt weeds at low tide — probably not 

 many more than 400. 



Numenius phaeopus. Whimbrel. 



A fair number in the Canche estuary on 12 Mky ; iu good 

 numbers there as early as 28 and 31 July, 1918. 



Charadrius apricarius. Golden Plover. 



Heard at night on 13 April at St. Emilie, near Epehy ; 

 and on the night of 30 July, 1918, passing over Etaples, 

 flying south-west. 



Squatarola squatarola. Grey Plover. 



Four in the Canche estuary with some knots on 16 October. 



JEgialitis hiaticula. Ringed Plover. 



Small flocks in the Canche estuary in October and 

 November — never more than a few score ; on 31 July, 1918, 

 three birds about some rough sandy ground a few hundred 

 yards north of the Canche estuary and near the railway. 



Vanellns vanellns. Lapwing. 



An uncommon bird, only seen at migration time : a flock 

 in March 1917 at Pontr^my near Abbeville; one bird at 

 Le Mesnil Bruntel near Peronne on 18 April ; in the late 

 autumn 40 or 50 in the Canche estuary on 16 and 17 

 November ; in March 1918, flocks at Adinfer on the 23rd, 

 and at Sarpignies, near Bapaume, flying over during the 

 battle on the 25th. 



Captain Dunkerley of No. 2 Squadron, R.P.C., tells me 

 that about 9 March, 1918, he ran into a flock of what were 

 evidently lapwings flying north at a height of 6500 feet 

 over the line at Hulluch near Lens. All pilots and men in 

 observation balloons that I have questioned agree that they 

 rarely see birds at a height of more than 3000 feet.
