摘要: Abstract Many species, including shorebirds, feed during both day and night, yet little is known about how this affects behavior habitat preferences. European Golden-Plovers (Pluvialis apricaria) Northern Lapwings (Vanellus vanellus) feeding on arable farmland were more widely dispersed at night: nocturnal flocks smaller, typically monospecific, occurred in many fields than diurnal mixed-species flocks. Diurnal numbers of could not be used to predict numbers; indicates that ranging differed between night. For was recorded almost all nights, irrespective moon phase. Lapwing activity decreased with increasing cloud cover decreasing ground temperature, but no clear relationships detected Golden-Plovers’ environmental variables. Habitat selection species Diurn...
