BIRDS OF OKANJANDE AND OUTJO. 53 



appeared to me that the head and neck are thrown back- 

 wards along the back ; at any rate the bird goes straight up 

 into the air to a height of 30 or 40 feet, for all the world us 

 if someone had thrown a dead bird up into the air. No head 

 or neck can be seen, until the bird is descending, when the 

 head is thrown forward and the bird drops to the ground in 

 a normal manner. 



14. Otis afroides — White-quilled Black Korhaan. 

 Common everywhere throughout the district^ wherever 

 patches of open grass country occur. I have noticed a 

 curious habit of this bird — viz., that of pursuing and mobbing 

 jackals whenever these animals are discovered by them in 

 the open. I have noticed that specimens shot in this country 

 have a white rinor surroundino- the brown of the crown.

15. Anthropoides paradisea — Blue Crane. I saw a 

 pair of these birds on the border of the Etosha Pan. 



16. Actophilus africanus — African Jacana. I found 

 a pair of these birds on a large rain-vlei near the Waterberg 

 and secured a female. 



17. Turnix lepurana — Kurrichane Button-Quail. 

 Very common, especially in the Outjo district. I have never 

 seen so many button-quails before in my life, as I did 

 one day in June when driving through some long grass ; 

 they were rising in twos and threes every few yards, for 

 miles. 



18. Pterocles gutturalis — Yellow-throated Sand- 

 Grouse. I have met with this species only in the sand-veld 

 to the south-west, when I located a few pairs along the 

 sandy roads. 



19. Pteroclurus namaquus — Namaqua Sandgrouse. 

 I have never seen this species in the Okanjande district, but 

 in the Outjo district it wtiS very common^ large numbers 

 regularly visiting the water-holes to drink. 



20. Abdimia abdimii — White-bellied Stork. In 

 March, after we had had good rains and all the country 

 was looking beautifully green, large flocks of these birds
