under their perches like LoricuJi, always crowding together 

 into as compact a bunch as possible. One characteristic 

 position is to let themselves down behind the twig on which 

 they are perched until only their bills and eyes appear 

 over the top of it. A row of them will maintain this position 

 for an hour at a time — looking precisely as if they were 

 drawing themselves up to the chin on a horizontal bar.

We first came across the White-crested Turaco in the 

 forests near the Khor Gitti. From there to Chak Chak it 

 was fairly common.

 tree in fruit. They have a variety of croaking cries, but are 

 not nearly such noisy birds as the Schizorhis. Sometimes, 

 in the shade of the forest, their wings appear of quite a bronzed 

 chestnut colour, and they might in flight almost be taken at a 

 distance for some white-headed species of Centropus, but in 

 the full sunlight the vivid crimson of the wings shews most 

 conspicuously. The Golo natives called the bird " Kombo.^'

These noisy and conspicuous Grey Plantain-eaters were 

 abundant from Ayum to Chak Chak. They are as active as 

 a squirrel in running along branches, and ai*e extraordinarily 

 good runners on the ground. At Dud Majok I noticed a 

 bird which had injured its wing and was sitting in a small 

 tree by itself. The Jur natives who were with me shook it
