Post-copulatory sexual selection and the Zebra Finch
TLDR
The outcome of sperm competition in the Zebra Finch and other birds is best predicted by the passive sperm loss model, allowing for differences in sperm numbers and quality (fertilising capacity); last male sperm precedence is not a ‘rule’ in birds but is a consequence of the way sperm competition experiments have been conducted.
Copulation patterns and sperm competition in the polygynandrous Smith's longspur
TLDR
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.
Sperm competition in the European starling (Sturnus vulgaris): an experimental study of mate switching
TLDR
This study evaluates sperm competition in the European starling by means of a mate-switching experiment and finds that the success of extra-pair copulations more than 2 d before egg-laying is probably very low.
Prolonged copulation, sperm reserves and sperm competition in the Aquatic Warbler Acrocephalus paludicola
TLDR
Frequent insemination during protracted copulation and contact mate guarding may be alternatives to paternity guarding found in other birds.
Frequent copulation as a method of paternity assurance in the northern fulmar
Why Does the Typically Monogamous Oystercatcher (Haematopus Ostralegus) Engage in Extra-Pair Copulations?
TLDR
It is suggested that EPCs were not necessarily beneficial, even when there was no apparent risk of a penalty by the mate, and an increase in the probability of mate change when an individual has engaged in EPC's in the previous year.
Copulation behaviour of the Black Kite Milvus migrans in Nagasaki Peninsula
TLDR
There was no relationship between courtship feeding and copulation; that is, presentation of food to the female by her partner was not a prerequisite for copulation.
Copulation rate and sperm use by female bearded tits,Panurus biarmicus
TLDR
The rate of sperm loss from the female's reproductive tract was obtained for the first time for a wild bird and was relatively high compared with other birds, suggesting that bearded tits copulate frequently because a single insemination is insufficient to fertilize the whole clutch, and females thus have to copulate during the egg-laying period to avoid infertile eggs.

Extra-pair copulation and sperm competition in the zebra finch
TLDR
It is shown that EPCs occurring under semi-natural conditions in captivity result in extra-pair paternity, and sperm from the last male to mate has precedence over previous matings: a single EPC occurring last is disproportionately successful in fertilizing eggs, butEPCs followed by further pair copulations have a low probability of success.
Behavioural Aspects of Sperm Competition in Swallows (Hirundo Rustica)
TLDR
Male swallows allocated their ejaculates at an optimal time of the season and the day, and male mates prevented cuckoldry threats by increasing copulation rates if their female mates were chased by neighbour males.

Intraspecific Variation in Extra-Pair Copulation and Mate Defence in Common Guillemots Uria Aalge
TLDR
The reproductive success of males obtaining EPCs, cuckolded males, and non-EPC/non-cuckold males was examined, and a selective advantage of 10% estimated for successful EPC males over cuckolds was estimated.

Polyandry, cloaca-pecking and sperm competition in dunnocks
TLDR
Sperm competition is described for a small European passerine bird, the dunnock (Prunella modularis), where females are often mated simultaneously to two males and where there is an elaborate pre-copulatory display.
Extra-Pair Copulations and Mate Guarding in the Polyterritorial Pied Flycatcher, Ficedula Hypoleuca
TLDR
It is most likely that male reproductive strategies are not maintained as a frequency-dependent mixed ESS with equal pay-offs for all paired males, Instead, male strategies are conditional on phenotype and breeding circumstances.
Copulation Behaviour of Birds
TLDR
The predation and social bond hypotheses were not totally dismissed, but there was no evidence that fertilization ability was limited by copulation frequency (i.e. the fertilization hypothesis), and the sperm competition hypothesis was supported.
