COLLOCALIA ESCULENTA (L.) . 



Builds its nests on the sandstone rocks bordering the Street 

 Limbe in the north-east of the Minahassa, but occurs also in 

 many other places in this district, 



Macropteryx wallacii (Gould). 



Malay native name, '' Burong-pedang/' i. e. '' Knife-bird/' 

 because its wings are shaped like a knife. 



Near Menado in March, Togian Islands in August. 

 Iris brown ; feet grey ; claws blackish ; bill black. 

 Feeds on insects. 



BucEROS EXARATUS, Tcmm. 



Native Malay name, " Karaka '' (this is its cry) . Alfurous 

 name in the north of the Minahassa, " Karokok ;" in Ton- 

 dano, " Kerek-kerek.^' 



(Native names often change from village to village, as the 

 native language generally does in these parts of the East.) 



The male is not pure white on the sides of the neck, but 

 often yellowish. 



These birds live in pairs together. Their flight is heavy and 

 loud. They feed on fruits, such as waringui [Urostigma) ; 

 and large flocks are often to be seen together on high fruit- 

 trees. A common bird, not restricted to the north-eastern 

 parts of Celebes, as I also found it near Paguatt, in the Gulf 

 of Tomini, in September. It makes its nest in hollow trees 

 or between wood, and lays two eggs. 



Cranorrhinus cassidix (Temm.). 



Native Malay name, " Burong-taun,^' i. e. " Year-bird " 

 (see explanation of this name below). Alfurous name, 

 '^ Uwak " (which is its cry) . 



I did not find this Hornbill in the neighbourhood of Me- 

 nado, but at Lotta, six miles from there, in the mountains of 

 the Minahassa, at all times, in the district of Gorontalo, 

 where I saw large flocks when crossing the island from 

 Gorontalo to Kwandang, and on the Togian Islands. The 

 bird on the wing is a fine sight, the vividly coloured head 

 being visible from far. As one looks down on a forest from 

 a high point, it appears to swim over the green foliage more
