Abstract DNA fingerprinting showed that 15% of 62 house martin nestlings at study colonies in central Scotland were not related to their putative fathers, and 32% of 19 broods contained at least one extra-pair chick. There was no evidence of intraspecific brood parasitism. Birds were never seen to mate outside nests in the vicinity of nesting colonies, and the single copulation that was observed during this study was a pair mating that took place inside a nestbox. Extra-pair birds were often… Expand
Timing of copulations and the pattern of paternity in relation to laying order in tree swallows Tachycineta bicolor
TLDR
Examination of nestling paternity with respect to laying order in eighteen mixed-paternity tree swallow broods found no evidence of an increased frequency of extra-pair young with laying order, and extra- Pair young appear to be randomly distributed within the laying sequence of tree swallows.

Male-only care and cuckoldry in black coucals: does parenting hamper sex life?
TLDR
The results suggest that real-life care situations by males may involve trade-off structures that differ from, and are less strict than those frequently employed in theoretical considerations of operational sex ratios, sex roles and parenting decisions. Expand
Brood parasitism in the sand martin,Riparia riparia: evidence for two parasitic strategies in a colonial passerine
TLDR
It is proposed that the relatively high frequency of QP found in sand martin parentage is unlikely to be due to chance events and may represent a female-driven strategy. Expand
Within-clutch patterns of egg viability and paternity in the House Sparrow
TLDR
This study has used single-locus minisatellite and microsatellite profiling to investigate the distribution of extra-pair fertilizations within House Sparrow broods to determine whether there are changes in the level of hatching failure or extra- Pair paternity during the course of producing a clutch.

Evidence for a maternal effect benefiting extra-pair offspring in a songbird, the house wrenTroglodytes aedon
TLDR
It is suggested that EP offspring are more likely than WP offspring to occur in earlier-laid eggs, thus gaining a size-based competitive advantage, and recommended that, when comparing EP and WP half-siblings in species in which eggs hatch asynchronously, researchers test for this potential maternally derived effect on offspring performance.

The effectiveness of mate guarding by male black-throated blue warblers
TLDR
Examination of mate guarding by male black-throated blue warblers showed that males that guarded their mates more closely were less likely to have extrapair young in their nests, and the experimental detention of a male for 1 h during the fertility risk period increased the probability that a brood would contain extrapairYoung. Expand
Paternity and parental care in the black-throated blue warbler, Dendroica caerulescens
TLDR
It is suggested that ASY males may be able to assess their paternity, possibly by using cues related to levels of local synchrony during their females' fertile periods, and adjust their care accordingly. Expand
Differential Food Distribution by Male and Female Green-Backed Tits (Parus monticolus) in Relation to Nestling Size
TLDR
The results suggest that the food-distribution pattern in Green-backed Tits is determined not only by nestling behavior but also by parentally biased favoritism toward nestling size. Expand
Paternal care declines with increased opportunity for extra–pair matings in fairy martins

TLDR
A novel remote monitoring technique is used to show that participation in incubation by male fairy martins, Hirundo ariel, declines with the increasing availability of fertile females in the breeding colonies, and that this trade–off may be widespread among the 90% of bird species where males contribute to parental care.

Age-Related Variation in Mate-Guarding Intensity in the Bluethroat (Luscinia s. svecica)
Female extra-pair copulations (EPCs) have selected for male paternity guarding strategies in many bird species. In the bluethroat, Luscinia s. svecica, males guard their mates closely during the lastExpand
