650 BIRDS OF SOUTH AFRICA. 
Mr. Andersson says:—‘ This Jacana is common in the Lake- 
regions and on the Okavango, where it breeds; but it is very rare 
in Damara Land, and, I believe, is never seen in Great Namaqua 
Land.”

622. GLAREOLA MELANOPTERA, Nordm. Black-winged Pratincole. 
Glareola nordmanni, Layard, B. S. Afr. p. 291. 
This Pratincole differs from the European bird, and may at once 
be distinguished from it by the under side of the wings, which in 
this species is black, in the other rufous; it has also a longer tarsus 
and shorter toes and tail. It appears in great numbers on the 
eastern frontier and Natal during the visitations of the locusts, upon 
which it feeds. We are informed that it hawks about the clouds of 
the destroying insect, now and then darting into the mass, and 
never failing to secure a victim. It is said to run and fly with great 
swiftness. 
Mr. Rickard has met with this species near Port Elizabeth and 
East London. He writes:—“‘I have frequently seen ‘ Locust 
Birds,’ but never where there were any locusts. I have also seen 
swarms of locusts, but always unattended by G. melanoptera.” 
Captain Trevelyan records it as migratory near Kingwilliamstown, 
coming at times in large numbers. 
Mr. Ayres has obtained it in Natal, and Major Feilden observed 
it in large flocks on the way up country in March. Major Butler 
and Captain Reid state that “the first pair was seen by them near 
Newcastle on the 19th of October. In November they were most 
abundant in flocks in the neighbourhood of Ladysmith and Colenso,
