Table 1 The variables analyzed in experiments regarding landing, time allocation, and food exploitation. Variable abbreviations are in parentheses

From: Energy state affects exploratory behavior of tree sparrows in a group context under differential food-patch distributions

Variables Descriptions
Landing
 First landing latency (FLL) The duration between an entry into the aviary and the first landing of a sparrow on the ground.
Time allocation
 Exploration time (ET) The duration of a sparrow spent on the ground before the first patch discovery.
 Exploring-feeding time (EFT) The duration of a sparrow spent on the ground after the first patch discovery.
Food exploitation
 Food consumption (FC) Amount of feed consumed by a sparrow.
 Ground-feeding rate (GFR) Amount of feed consumed by a sparrow per second on the ground [FC/(ET + EFT)].
 Food consumption as finder (FCF) Proportion (%) of feed consumed by a sparrow via active patch discovery.
