MIGRATION OF BIRDS 
coast. The earliest record which I have is October and the 
latest May 28. 
I suspect that some birds remain here through the summer. 
78. The Golden Plover ( Charadrius pluvialis) has been 
reported, but the occurrence of this species here is doubtful. 
79. The Grey Plover ( Squatarola helvetica) breeds in 
Arctic Europe, Russia, and Asia. Fair numbers are to be seen 
on the coast between October and March. 
80. The Ruff and Reeve (Machetes pugnax) breeds in 
the northern half of Europe and Asia. Is common here in winter 
from September to March ; but I have shot them as early as 
August and as late as May. 
81. The Knot (Tringa canutus) is said to breed in the 
north of the New World and possibly Asia ; thus its occurrence 
here is interesting. I have not collected it, but one specimen 
has been shot by A. Blayney Percival in December. Whether 
it is a regular migrant to this country I cannot say. 
82. The Turnstone (Strepsilas interpres) breeds in Green- 
land and Arctic regions. A few specimens have been taken 
in this country. A small flock of four were seen by me at 
Lake Nakuru, but they were extremely wild. 
88. The Sanderling (Calidris arenaria). — Greenland and 
Arctic regions and Spitzbergen have been given as the breeding 
places of this species. They are common here, along the 
coast and on inland waters, where there is a sufficient stretch 
of sand or mud. The earliest record which I have is November 
and the latest March. 
84. The Dunlin ( Tringa alpina) is a resident and winter 
visitor to Europe ; a few come here between November and 
January and remain till March. 
85. The Curlew Sandpiper (Tringa subarquata) breeds 
in the extreme north of Europe and Asia, from which localities 
they depart for the south in August. From my records, I 
find that the first arrivals to turn up here were in August, 
but just a few. The majority arrived in October and remained 
in large numbers up to March. Odd flocks of half a dozen 
birds each were noted, and specimens obtained therefrom 
during May of this year at Nakuru Lake. In looking at this 
series it will be noticed that although the majority of birds
