He focused on the behavior and ecology of various species, particularly in the context of their habitats. His work helped to enhance the understanding of avian life in Scotland and beyond. Montgomerie is also recognized for his research on sexual selection and mating systems in birds. His studies have provided valuable insights into how these factors influence bird populations and their evolutionary processes. His findings continue to be referenced in the field of ornithology today.
