though the bulk of the migration takes place in March, the! , 

 laying of the eggs taking place about the ist of May. 



The food of the present species consists of all kinds oft 

 carrion, dung, and putrefying substances of all sorts. It will! 

 take its meal from a carcase after the Hyaenas and Griffons! 

 have had their share, and even frequents the sea-shore to I 

 pick up rotten fish thrown up by the tide. Though repul-1 

 sive in its habits, everyone admits that the Neophron is al 

 fine bird on the wing. In the Himalayas I found the Indian! 

 representative of the genus inhabiting the lower valleys, where 1 

 they sailed majestically backwards and forwards, scanning the! 

 ground below. At Simla they never ascended to the higher! 

 portions of the mountains, where the Griffons were to be seen I 

 topping the crest in the early morning on their far-reaching | 

 course, but hundreds of feet down below one could see the I 

 White Scavengers sailing in the valley in circles or in a direct I 

 line. 



From their habits one can gather the idea of what their nest t 

 may be like. Here is the description given by that excellent I 

 observer, Colonel Irby, in his work on the " Ornithology of fi 

 the Straits of Gibraltar " : " The nest is often easily accessible I 

 from below, and, placed on a ledge of some overhung rock, I 

 generally at the top of a sierra, is composed of a few dead I 

 sticks, always lined with wool, rags, and rubbish, such as a I 

 dog's head, boars' tusks, dead kittens, foxes' skulls and fur, I 

 rotten hedge-hogs, dead toads, dead snakes, skeletons of I 

 snakes, lizards, mummified lizards, lizards' heads, carapaces I 

 of the water-tortoise, rotten fish, excrement both of man and | 

 beast, bones, bits of rope and paper. In one nest Major 

 Verner found, among a heap of filthy rags, a number of meal- 

 worms. Probably the Neophron had picked up a bag with 

 some flour in it. Naturally, from the above-mentioned con- 

 tents, their nests are most offensively odoriferous ! " He 

 further adds : " They are probably among the foulest feeding 

 birds that live, and are very omnivorous, devouring any animal 

 substance, even all sorts of excrement : nothing comes amiss 

 to them."
