Abstract
A survey of anthocyanidin pigments of 146 species of bird-visited flowers indicated a bird-visitation pigment syndrome that was generally uniform across wide geographical distances. Pigments of bird-visited flowers of Australia and New Zealand were somewhat distinct from this pattern, an observation that is attributed to phylogenetic constraints in these floras. No evidence for pelargonidin enrichment in tropical floras was detected. The pigment syndromes of perching and hovering birds were distinct.
