386 Lieut. C. B. Ticelnirst on the [Ibis, 



Knot, 



Fair numbers on tlie sbore in Aii^-ust; a few red adults 

 noted. Very numerous in September, laro-e increase on the 

 19th. Noted arriving over the island^ high up, coming 

 from the north-east on the 25th. By the first few days of 

 October the numbers had largely diminished, but there were 

 further arrivals on the 10th. The stomachs of all those I 

 examined contained shoots of a marine plant, 1 think 

 sea-samphire. " A fevs'' in breeding-plumage, no big 

 flocks" (V.). 



Sanderling. 



Two seen on the sandy shore to the west of the island on 

 20 September were the only specimens which came under 

 observation. Possibly commoner than was apparent, but 

 the tide's edge was not visited every day ; indeed, it was 

 sometimes not to be seen. 



Ruff. 



I think that by 24 August the majority had left ; we saw 

 several young birds in the Polder het Noorden ou that date, 

 but on the 2<stli only four, and an odd bird on the shore on 

 the 31st. Not met with in September. " Breeds commonly 

 in all the polders " (all authors). " Also breeds on the other 

 Dutch islands" (L.J.). It is interesting to note that the 

 early date of dej)arture from the breeding-grounds roughly 

 corresponds with the date on which this species may be 

 looked for in England. 



Common Sandpiper. 



A good many seen in the Polder het Noorden on 24 

 August, and odd ones on tlie edge of the shore, whither 

 many came out from the polders to feed at dusk. Single 

 bird on 8 September and six the next day were noted. 

 " Seen in May ; possibly breeds '■' (Y.). " Erroneously 

 recorded as a breeding species for the Dutch islands Ity 

 Schlegel" (L.J.). 



Wood-Sandpiper. 



One or two seen in the dvkes of the polders in August.
