MIGRATION OF BIRDS 
birds first arrive, but they have been collected between 
November and January. 
60. The Spotted Crake (Porzana maruetta) also occurs 
here in winter, but dates of arrival and departure are not 
known. The specimens exhibited were shot in December 
and January. 
61. The Waterhen (Gallinula chloropus) probably does 
not come this length, the birds found here belonging to the 
local African form. 
62. The Common European Quail (Coturnix coturnix) 
has been recorded, but it is difficult to distinguish from the 
Cape Quail, which is a resident and breeding species in these 
parts. 
68. The Spoonbill (Platalea leucorodia) has been recorded. 
Several Spoonbills have been seen on Lakes Victoria, Naivasha, 
and Nakuru — probably P. alba, but this needs verification. 
64. The Glossy Ibis (Plegadis falcinellus) occurs in the low 
country along the basin of the Danube, in South Russia, and 
some islands of the Mediterranean ; they are also resident 
and breed in this country. The presence of winter visitors 
requires confirmation. 
65. The Common Grey Heron (Ardea cinerea) has been 
reported, but occurrence is doubtful ; specimens exhibited 
are of the local form (A. melanocephala). 
66. The Purple Heron ( Ardea 'purpurea ) is resident and 
breeding here. Numbers may be increased during the winter. 
67. Ducks. — Gargany, Shoveller, and Pintail breed in the 
sub- Arctic regions of Europe and Asia. Visit the lakes in these 
parts and are most plentiful in November to January. 
68. The European Pratincole (Glareola pratincola) has 
been recorded, but these are probably examples of the African 
forms. They may be met with throughout the year. Speci- 
mens exhibited are birds collected November, January to 
March ; and others have been recorded from the Toro Lakes 
in June and July. 
69. The Barn Owl (Strix flammea, sub-sp.), which occurs 
in this country, has been recognised as a sub-species of the 
European ; but this form also occurs in Eastern Europe. It is 
doubtful whether it is a migratory bird at all.
