MIGRATION OF BIRDS 
289 
are well on in assuming the summer dress by March, yet some 
of those collected in the latter part of May show little signs 
of change (of. Stints) ; indeed, one male, instead of assuming 
the red-brown feathers of the spring plumage, is still shedding 
those of the previous year. 
86. The Little Stint ( Tringa minuta) breeds in the north 
of Siberia and Europe, leaving these districts towards the 
end of August ; they arrive here in fair numbers in October, 
some birds showing remains of the summer plumage, others 
in full winter dress. In December and January they begin 
to assume the spring plumage, but some are very late in doing 
this ; thus amongst the series exhibited there is a male in almost 
full plumage shot in February ; others again, collected in May, 
show no change. Most May birds are fairly full-plumaged. I can- 
not say when these birds left Lake Nakuru, but I am almost 
certain that some would remain there throughout the summer. 
87. The Common Sandpiper ( Totanus hypoleucus ) is found 
over Europe generally, and winters in the Tropics. Some birds 
are undoubtedly resident in this country, for we have taken 
a female with newly hatched young, and, again, I have records 
of specimens being seen at Nakuru Lake in June and July. Fair 
numbers of migrants come here in September and remain till 
March, when they disappear. 
88. The Wood Sandpiper ( Totanus glareola) breeds in 
Northern Europe and Asia. Common migrants to these parts. 
Most arriving in November and remaining on, apparently, till 
April and even May. 
89. The Green Sandpiper ( Totanus ochropus), during the 
summer, breeds in Northern Europe and Asia. It is a common 
migrant, arriving here early in October and remaining in more 
or less steady numbers until March ; they then may be seen 
in odd pairs up to May, and once I saw a specimen in Nairobi 
area in June ; it was, however, a bird that had had an injury 
to its wing, and although able to fly had not gone north. 
90. The Greenshank ( Totanus glottis) breeds in North 
Europe and Asia, including the north of Scotland. Has been 
taken here between December and March. Though not 
having actually shot a specimen, I saw them at Nakuru Lake in 
December, in small flocks of three to five individuals.
