Want to know:

Toucans are frugivorous (fruit-eating) birds that inhabit tropical forests in Central and South America where they can potentially consume any fruit that is available (generalists). The realized niches of toucans are determined by competition in the consumption of different species of fruits (niche overlap). White-throated toucans are the largest species and very strong competitors who easily scare the mid-sized Cuvier's and Ivory-billed toucans off the fruiting trees, altering access to the resources among the three species. The graphs shown represent the occupation of niche space at two different sites, where two or three species coexist, in different abundances.
