We devoted a good deal of our time and patience to getting 
together a collection of all the Hornbills of the Zambesi 
region, none of which can be called common; but this 
species is perhaps the most numerous. We met with it in 
fair numbers near Tete and again at Chicowa. The birds 
were in flocks and were as shy and wary as they could be, 
giving us little opportunity of approach within gunshot. But 
eventually, after several futile attempts to obtain specimens 
by walking towards them, we got to know the particular 
trees to which they used to repair on the approach of danger, 
and by hiding near one of these favourite resorts and having 
the birds driven towards it we procured a very fair number 
of specimens of both sexes, and chiefly adult birds. The 
vicinity of water is essential to this species. 
During the cool of the morning and evening they used 
to troop down to the river as regular as clockwork, and then 
back again to their old haunts, which are seldom deserted 
for others. The confines of thick woods where the under* 
growth is small and interspersed with high baobab-trees are 
favourite localities. And in the holes of these baobabs they 
spend most of the day, for they appear to dislike the heat 
very much. On the approach of the pairing-season in 
November, they scatter and hide themselves away in thick 
woods, often filling these silent places with their peculiar
