About
Hannah E. A. MacGregor is a behavioural ecologist whose research explores the fascinating intersection of animal communication, colouration, and social signalling. Her most influential work, "Dynamic eye colour as an honest signal of aggression" (2018), has garnered 21 citations and established her as a leading voice in understanding how rapid physiological colour changes—like shifts in eye hue—function as reliable indicators of intent in social animals. By demonstrating that such dynamic traits can serve as honest signals of aggression, MacGregor has challenged traditional views of static colouration in signalling theory, offering new insights into the evolution of visual communication. Her work bridges ethology and sensory ecology, with implications for both vertebrate and invertebrate systems. Beyond this landmark paper, MacGregor’s contributions have been recognized for their methodological innovation and theoretical depth, making her a rising figure in the study of animal behaviour. For students and researchers, her research provides a compelling framework for investigating how subtle, real-time signals shape social dynamics and conflict resolution in nature.
