Communication in the third dimension: song perch height of rivals affects singing response in nightingales. [PDF]
Many animals use long-range signals to compete over mates and resources. Optimal transmission can be achieved by choosing efficient signals, or by choosing adequate signalling perches and song posts. High signalling perches benefit sound transmission and

General Behaviors and Perching Behaviors of Laying Hens in Cages with Different Colored Perches [PDF]
Color is one of the perch properties. This study was conducted to investigate the general behaviors and perching behaviors in laying hens under different group size (stocking density), and to understand the perch color (black, white or brown) preference ...
