 | | Since the time of those excellent ornithologists our knowictlge of the hornbills has been steadily increasing, but up to the third quarter of the IQth century there was a great lack of precise information, and the publication of D.

 | | Hornbills are social birds, keeping in companies, not to say flocks, and living chiefly on fruits and seeds; but the bigger species also capture and devour a large number of snakes, while the smaller are great destroyers of insects. |
