From: Foraging guild structure and niche characteristics of waterbirds in an epicontinental lake in Mexico
Cluster analysis of waterbird species by both niche dimensions (feeding technique and habitat use). The average Euclidean distance between all species pairs is indicated by a dashed line (mean = 1.314). Guild codes for the obtained guilds are (G1) divers; (G2) pickers in water, mud, and vegetation; (G3) pickers with neck submerged; and (G4) generalists.
