Behavioral measurements of the foraging strategies of little egret and common goldfish, in a laboratory theater

Measurements of the behavioral foraging strategies of little egret (Egretta garzetta), and common goldfish (Carassius auratus), in a laboratory theater containing three fish pools in two experimental treatments. One experiment used a homogeneous environment: fifteen fish per pool, and the second experiment used a heterogeneous environment: pools 1, 2, and 3 had ten, fifteen, and twenty fish, respectively
