Grey Heron (Ardea cinerea) Expansion Promotes the Persistence of Mixed-Species Heron Colonies [PDF]
Waterbirds, 2014 Abstract. Range expansion of native as well as exotic species often causes effects on the original species; however, not all range expansions are negative for breeding colonies consisting of mixed species. The Grey Heron (Ardea cinerea) has increased and expanded its distribution in Japan in the last 20 years.
