SummaryA population of white-crowned sparrows (Zonotrichia leucophrys oriantha) located near Tioga Pass, in the central Sierra Nevada of California, was studied during the 1985 and 1986 breeding seasons to determine how often chicks were not the offspring of both adults who reared them. Blood samples were obtained from 35 nesting pairs and feather pulp specimens were collected from all 110 young they fledged. Electrophoretic analyses of 4 polymorphic loci revealed that a minimum of 9 nests (26… 

Patterns of extra-pair fertilizations in bobolinks

SummaryWe studied patterns of paternity in 840 nestling bobolinks (Dolichonyx oryzivorus) from 191 pairbonded adults and the chicks they reared in west central New York, USA, during 1983–1986, using

Genetic evidence for extra-pair fertilizations in a monogamous passerine, the Great Tit Parus major

TLDR
The results suggest a mixed reproductive strategy for males in which they breed mo-nogamously whilst simultaneously seeking extra-pair matings with females of other pairs.

Female control of extra-pair fertilization in tree swallows

TLDR
Experimental evidence for female control of copulations and fertilizations and the occurrence of two alternative copulation strategies among females in a Canadian population of tree swallows are reported, concluding that fertilization patterns to a large extent are determined by the female through active selection and rejection of copulation partners.

Evidence for Genetic Monogamy But Low Mate Retention in the North American Black Tern (Chlidonias niger surinamensis)

TLDR
The results of this pilot study provide the first evidence of genetic monogamy in Black Terns and suggest that low mate fidelity is related to low breeding site fidelity, a characteristic common in birds that breed in unstable habitats.

Determinants of parental care in Mountain White-crowned Sparrows (Zonotrichia leucophrys oriantha)

TLDR
It is suggested that mate quality is a predictor of food provisioning behavior in males but not females, thus providing some sex-specific support for the differential allocation hypothesis, while finding conclusive evidence for the good parent or reproductive compensation hypotheses.

Low frequency of extra-pair paternity in pied flycatchers revealed by DNA fingerprinting

TLDR
The fact that many males in this study started to advertise for a second female in a distant territory several days before their first mate began egglaying, and still managed to secure almost exclusive paternity in their first brood, suggests that male polyterritoriality is not costly in terms of lost paternity.

Low frequency of extra-pair paternity in Common Gulls (Larus canus) as revealed by DNA fingerprinting

TLDR
Blood samples of 24 Common Gull (Larus canus) families from two Polish colonies were analysed using DNA fingerprinting to fill the gap in the mating systems of many bird species using molecular genetic methods.

Extra-pair paternity in tree swallows: why do females mate with more than one male?

TLDR
It is suggested that most extra- Pair copulations occur at some unknown location, possibly at a feeding or roosting area where females may be able to choose from many more potential extra-pair fathers than at their nest-site.

Extra-pair paternity and intraspecific brood parasitism in wild zebra finches Taeniopygia guttata, revealed by DNA fingerprinting

TLDR
Behavioural observations show that EPP occurs through extra-pair copulation rather than rapid mate switching in a wild population of zebra finches, and is discussed in the light of what is known about the fertile period and sperm precedence patterns in this species.

Extra-pair paternity in Seaside Sparrows

TLDR
This study determined the prevalence of extra-pair paternity in a large, socially monogamous population of Seaside Sparrows nesting in small, overlapping territories, using six microsatellite DNA markers and a likelihood-based approach to paternity assignment.

Electrophoretic and behavioral evidence corroborate the conclusion that Bob- olink (Dolichonyx oryzivorus) females occasionally copulate with more than one male, which results in the insemination of

Genetic Variation and Parentage in a California Population of Acorn Woodpeckers

TLDR
Examination of genetic variation in a California population of the highly social Acorn Woodpecker using starch-gel electrophoresis of 580 blood samples collected between 1975 and 1982 indicated kleptogamy (cuckoldry) in the study population.

Male parental care and extrapair copulations in the indigo bunting

TLDR
The results suggest that the relationship between mating effort and parental effort is complicated by the presence of extrapair copulations as a type of mating effort, and that factors not included in current theory on parental care might influence a male's parental care.

Forced Copulation in Waterfowl

TLDR
As HEINROTH suggested, FC probably does not occur in swans, most geese and shelducks because it is incompatible with the major roles that paired males play in defence of breeding territories, mates, nest-sites and broods in these groups.

ADVANTAGES AND DISADVANTAGES OF BANK SWALLOW (RIPARIA RIPARIA) COLONIALITY

TLDR
It is suggested that reduced predation on eggs and young, resulting from both gr ouLp defense and "selfish herd" effects, is an important advantage of Bank Swallow coloniality.

Sexual dimorphism in egg size and implications regarding facultative manipulation of sex in Mountain White-crowned sparrows

TLDR
The volume of male eggs in Mountain White-crowned Sparrows was slightly larger than that of female eggs in every year of a 5-year study, consistent with facultative manipulation of offspring sex as proposed under the Trivers and Willard hypothesis.

Biochemical determination of parental uncertainty in white-fronted bee-eaters

TLDR
A comparison of estimates from biochemical and behavioral analyses indicates that both methods can produce misleading results, and a possible use of maximum likelihood techniques to separate the sources of non-kin is discussed.
