Egg rejection is an effective and widespread antiparasitic defense to eliminate foreign eggs from the nests of hosts of brood parasitic birds. Several lines of observational and critical …
What makes a perfect signature? Optimal signatures should be consistent within individuals and distinctive between individuals. In defense against avian brood parasitism, some host …
animals, including humans, decisions often rely on the ability to tell the difference between things that vary in size or magnitude. From choosing the larger food item to estimating an …
According to Weber's law of proportional processing, perceptual discrimination between stimuli of different magnitudes is based on their proportional differences in magnitude (not …
Obligate brood parasitic birds lay their eggs in the nests of other species, reducing the host's own reproductive output. To circumvent these fitness costs, many—but not all—host species …
