由于社会学习和物种间觅食专业化的多样性，混合物种觅食集群为每个个体提供了更广泛的食物项目（Krebs 1973）。技能库效应应该为没有社会学习的单一物种觅食群体提供类似的好处。当不同的觅食专家加入其他人的发现时，技能库就出现了。在提供更多种类的食物的同时，它还通过专业化提高了个体觅食效率。当个体学习在觅食行为的发展中起重要作用时，它应该产生频率依赖效应，促进个体专业化，有利于技能库的发生。从技能池效应产生的几个生态和行为的预测，需要更多的注意个人的饮食和行为的比较内外觅食组。
Mixed-species foraging aggregations provide each individual with a wider range of food items as a result of social learning and the diversity of foraging specializations among species (Krebs 1973). The skill pool effect should provide similar benefits to single-species foraging groups without social learning. The skill pool occurs when different foraging specialists join the discoveries of others. While providing an increased range of food items, it permits increased individual foraging efficiency through specialization. When individual learning is important in the development of foraging behaviors, it should generate frequency-dependent effects which promote individual specializations favoring the occurrence of skill pools. From the skill pool effect several ecological and behavioral predictions are generated that require more attention to comparisons of individual diets and behaviors inside and outside foraging groups.
