A variety of behaviours adopted by males before and after copulation serve to increase paternity. The most spectacular examples occur in insects where males increase their own chances of fertilizing the female's eggs by mate guarding, mating plugs and even removal of other males' sperm1,2. Here, sperm competition is described for a small European passerine bird, the dunnock (Prunella modularis), where females are often mated simultaneously to two males3,4 and where there is an elaborate pre…

COPULATION BEHAVIOUR OF BIRDS
- Biology
- 2016
Recent studies of extra-pair copulations and paternity in birds indicate that sperm competition may have been an important factor in the evolution of such reproductive behaviours as mate guarding and copulation.
Female Japanese quail (Coturnix japonica) mated with males that harassed them are unlikely to lay fertilized eggs.
- BiologyJournal of comparative psychology
- 2005
It is shown that a female quail choosing between a previous sex partner and an unfamiliar male avoids the former if he engaged in relatively many potentially injurious acts while courting and mating, and that males behaving aggressively toward mates are less likely than are gentler males to fertilize the females' eggs.
COPULATIONS AND MATE GUARDING OF THE SPOONBILL (PLATALEA LEUCORODIA)
- Biology
- 1989
It is considered that copulations are not completed without collaboration on the part of the female, their permissiveness towards EPCAs during the fertile period suggests advantages to females, and genetic quality of the offspring may be improved by this behaviour.

Cloacal pecking, in which a male pecks at the cloaca of a female, causing her to void sperm, was first described in the Dunnock (Prunella modularis), a species with a very complex group-breeding…

It is shown that in female feral fowl most copulations are coerced, and that females consistently bias sperm retention in favour of the preferred male phenotype.
Copulation patterns and sperm competition in the polygynandrous Smith's longspur
- Biology
- 1992
The occurrence of multiple mating by females and the lack of territorial behavior in males suggests that frequent copulations in this species evolved as an adaptation to sperm competition.

Female Promiscuity and Male Reproductive Success in Social Birds and Mammals
- BiologyThe American Naturalist

The model suggests that when promiscuity is advantageous to the female, a male should not interfere with copulations by other males when male-male cooperation is important to the survival of the young, and when subordinate males are likely to leave the group if prevented from breeding.

The semen of some passerine and non-passerine birds was examined, and the two types of spermatozoa were found to differ considerably in morphology and activity, the passerine form showing a spiral configuration and a helical forward movement.
