In the article, Potential winter niche partitioning between Tufted Titmice (Baeolophus bicolor) and Black-capped Chickadees (Poecile atricapillus) by Correia, black-capped Chickadee and the Tufted Titmouse competition was compared. Results show that Black-capped Chickadee tended to stay in the niche that was higher in ground than the Tufted Titmice that mostly done ground foraging. Since the Tufted Titmice is larger in size, it is hypothesized that Black-capped Chickadee avoided on purpose not to be on ground so that it would not have to compete. The data was collected by using a JC record to tape the behavior at the bird feeder. The location each bird stayed and forage was taken as data and the dot was used to tell how Black-capped Chickadee and Tufted Titmice interacted with each other.
