众所周知，犀鸟是杂食性的。在考艾国家公园研究的四种犀鸟的食物可分为动物和水果（进一步分为无花果和非无花果水果）。犀鸟消耗的不同食物的比例因物种而异。犀鸟吃的水果分为四类之一：肉质果肉和细粒种子（无花果），成熟时去壳，干燥的果肉带有单个石籽，以及柔软或多汁的果肉带有单个石籽。研究的四种犀鸟消耗的食物类型相对相似。雄性和雌性大犀鸟Buceros bicornis在分担喂养雏鸟的责任时，以及繁殖中的雄性无鼻犀鸟（Ptilolaemus）tickelli和巢帮手，在带入巢穴的食物方面表现出高度相似性。确定了食物偏好后发现，犀鸟更喜欢吃丰富的水果，而不是营养价值高的水果。除了无花果之外，在前 12 名中，最受 喜爱的是 Polyalthia viridis、Strombosia spp. 和 Horsfieldia glabra。所有四种犀鸟。动物性食品中，最受欢迎的是蜈蚣和蝉。
Hornbills are known to be omnivorous. The food of four hornbill species studied at Khao Yai National Park could be divided into animals and fruits (further divided into figs and non-fig fruits). The proportions of different foods consumed by hornbills varied from species to species. The fruits eaten by the hornbills were categorised into one of 4 groups: fleshy pulp and fine seeds (figs), split-husked when ripening, dry flesh with a single stone-seed, and soft or juicy flesh with a single stone-seed. The four hornbill species that were studied consumed relatively similar types of food. The male and female Great Hornbills Buceros bicornis, while sharing duty in feeding the nestling, and the breeding male Brown Hornbills Anorrhinus (Ptilolaemus) tickelli and nest helpers, showed high similarity of food brought to broods. Food preference was determined and it was found that hornbills feed more on fruits which are abundant rather than on fruits with a high nutritional value. Aside from figs, among the first 12 ranks, Polyalthia viridis, Strombosia spp., and Horsfieldia glabra were the most preferred by . all four hornbill species. Among animal foods, centipedes and cicadas were most preferred.
