A survey of 166 hummingbird species reveals novel associations of bill-length sexual dimorphism (BLSD) with plumage and breeding behaviours. Across all species, female bills become proportionately longer than male bills (higher female-to-male BLSD ratio) as sexual dichromatism increases. However, male bills are proportionately longer (lower female-to-male BLSD ratio) in both lekkers (traditional group display) and clustered breeders (female harems or colonial nests) compared with dispersed… CONTINUE READING
