Mutual ornamentation, age, and reproductive performance in the European starling

Komdeur, Jan; Oorebeek, Margot; Overveld, Thijs van; … - In: Behavioral Ecology 16 (2005) 4, pp. 805-817

ornamentation and age on breeding variables were hard to separate, so effects may be related to other age-related variables. This … provides a cautionary note for studies of ornamentation where age is unknown. However, we argue that throat feathers in …-related characters. However, only experimental manipulation can determine whether ornamentation signals quality variation within age …

Mutual ornamentation, sexual selection, and social dominance in the black swan

Kraaijeveld, Ken; Gregurke, John; Hall, Carol; Komdeur, Jan - In: Behavioral Ecology 15 (2004) 3, pp. 380-389

We investigated the adaptive significance of a sexually monomorphic ornament in the black swan Cygnus atratus. Both sexes grow curled feathers on their wings (range 7--22 curled feathers per wing), which are displayed prominently in a range of social interactions. The number of curled feathers...

Anna Qvarnstro¨m; Sheldon, Ben C.; Tomas Pa¨rt; … - In: Behavioral Ecology 14 (2003) 1, pp. 68-73

within-population variation in mating patterns. We investigated the influence of variation in male ornamentation and the … but that the costs of polygyny depend on an interaction between male ornamentation and timing of breeding. Among early …
