In each of four replicate experiments we fed three groups of bee-eater chicks for 24 h on different diets: bees, dragonflies, and a mixture of the two. 2. Dry weight assimilation efficiency did not differ between treatments and was in the region of 40-50%. Caloric assimilation efficiency was about 60% and did not differ significantly between diets. 3. Mean Growth efficiency (wt. gain/intake) was highest in all four replicates in chicks fed on the mixed diet. 4. When metabolic requirements are taken into account, growth efficiency on the mixed diet varies less with variation in intake than on the two pure diets. 5. The advantage of feeding chicks on a mixed diet may partly explain why parents do not show exclusive preferences for energy-maximising prey types.

在四项重复实验中，我们分别用三种不同的食物喂养三组食蜂鸟雏鸟24小时，这三种食物分别是蜜蜂、蜻蜓以及两者的混合物。2. 不同处理组之间的干重同化效率没有差异，大约在40%-50%之间。热量同化效率约为60%，不同食物之间没有显著差异。3. 在所有四项重复实验中，喂食混合食物的雏鸟平均生长效率（体重增加/摄入量）最高。4. 当考虑到代谢需求时，混合食物喂养的雏鸟生长效率随摄入量变化的幅度比两种单一食物喂养的雏鸟要小。5. 用混合食物喂养雏鸟的优势可能部分解释了为什么亲鸟不会对能量最大化的猎物类型表现出排他性偏好。
