许多物种，包括滨鸟，白天和晚上都进食，但很少有人知道这如何影响行为和栖息地偏好。欧洲金，Pluvialis pluaria）和北方麦鸡（Vanellus vancllus）饲养的耕地更广泛地分散在夜间：夜间的羊群较小，通常是单种的，并发生在更多的领域比白天的混合种群。欧洲金斑蝶的昼夜数量不能用来预测夜间数量，这表明白天和晚上的测距行为不同。对于这两个物种，夜间进食记录几乎所有的夜晚，无论月相。北方麦鸡的夜间取食活动随着云量的增加和地面温度的降低而减少，但没有发现欧洲金头麦鸡的夜间取食活动与环境变量之间存在明显的关系。栖息地的选择在白天和夜晚之间，以及在夜间的物种之间存在差异。对栖息地选择和地点选择的昼夜研究可能会歪曲这些物种的全部需求。
Many species, including shorebirds, feed during both day and night, yet little is known about how this affects behavior and habitat preferences. European Golden-Plovers (Pluvialis apricaria) and Northern Lapwings (Vanellus vancllus) feeding on arable farmland were more widely dispersed at night: nocturnal flocks were smaller, typically monospecific, and occurred in many more fields than diurnal mixed-species flocks. Diurnal numbers of European Golden-Plovers could not be used to predict nocturnal numbers; this indicates that ranging behavior differed between day and night. For both species, nocturnal feeding was recorded on almost all nights, irrespective of moon phase. Northern Lapwing nocturnal feeding activity decreased with increasing cloud cover and decreasing ground temperature, but no clear relationships were detected between European Golden-Plovers' nocturnal feeding activity and environmental variables. Habitat selection differed between day and night, and between species at night. Diurnal studies of habitat choice and site selection may misrepresent the full requirements of such species.
