Bird behavior, ecological theory, and natural history intersect at Bass Harbor Head in Acadia National Park

October 17 @ 12:00 pm - 1:00 pm

In 1958, Robert H. MacArthur published a study of the foraging behavior of five species of the genus Dendroica, (now Setophaga) Wood Warbler, stating each species concentrated foraging in distinct zones or niches within a tree. The theory of niche partitioning in warblers had a profound effect on the field of Ecology, influencing generations of students, scientists and the public perception of how the natural world works. In 2014-2015, Bik Wheeler, now a wildlife biologist at Acadia National Park, repeated MacArthur’s study in order to reassess warbler niche partitioning. His intention was to establish direct comparability with MacArthur’s research. Since MacArthur’s seminal work, the forest structure and warbler species assemblage, and taxonomic classification have shifted. These findings invite debate over the aptness of the popular ecological theory of niche partitioning to explain sympatry in this genus of warbler.
