Female sexual selection pressures in co-operative breeding species of birds

[L&L Knight <>]

ScienceDaily (Dec. 9, 2009) — Female birds in species that breed in  
groups can find themselves under pressure to sexually show off and
evolve the same kinds of embellishments -- like fanciful tail feathers  
or chest-puffing courtship dances -- as males, according to new
research in the latest issue of Nature (Dec. 10, 2009).
