I show that in dunnocks breeding territoriality functions exclusively for mate defense Naomi E. Langmore, Behavioral Ecology Vol. 7 No. 2: 183-188 Download article download full text (pdf)

Female control of copulations to maximize male help: a comparison ofpolygynandrous alpine accentors, Prunella collaris, and dunnocks,P. modularis
