664 Col. R. Meinertzhagen on Birds from [Ibis, 
MOTACILLA FLAVA. 
I have attempted in the following notes to collate from 
my own observations and from all published material a 
resume of the migratory movement of the races of Motacilla 
flava which occur in the Near East and in eastern Africa 
south to the Cape. 
Motacilla f. flava L. 
Autumn passage commences in Palestine in early August 
and in Egypt in late August, birds becoming common in the 
former country by 21. viii. and in Egypt by 8. ix. Passage 
continues till the end of September and early October. 
Birds do not remain through the winter in Palestine, but a 
few appear to do so in Egypt. 
In the Sudan they arrive throughout October and remain 
through the winter. 
They commence arriving in Kenya Colony and Uganda 
from 30. ix., and are common throughout the winter. 
Autumn migration passes well inland, down the Nile and 
Rift Valleys, only a few birds passing down the coast. 
Many birds continue south to Natal and the Transvaal, where 
I have seen them at Pretoria on 6.xi. and at Harrismith on 
4. xii. 
Birds commence to leave South Africa towards the end of 
March, and large numbers pass north through Kenya Colony 
throughout April. The latest spring record for eastern 
Africa seems to be 2. v., but the bulk have passed by 20. iv. 
This race was not noted passing up the coast of eastern 
Africa on spring passage. 
The masses of Yellow Wagtails of all sorts—mainly M. f. 
campestris — which collect at Entebbe at the north-western 
corner of the Victoria Nyanza from late March to late April 
form one of the most wonderful sights I have ever seen. 
Acres and acres of grass-land are carpeted with yellow, the 
birds huddled together, resting and feeding, many rising a few 
inches into the air, catching flies and mosquitoes, and others 
too tired to fly and merely running on before one’s feet
