• Brown Bag Discussion: Bird Behavior, Ecological Theory, and Natural History Intersect at Bass Harbor Head in Acadia National Park Oct 17, 12-1pm Free
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 sympatric warblers had a profound effect on the field of Ecology. In 2014-2015, I repeated MacArthur’s study in order to reassess warbler niche partitioning. My 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.
