Many organisms of temperate latitudes exhibit declines in reproductive success as the breeding season advances. Experiments can delay the onset of reproduction for early breeders to investigate the consequences of late nesting, but it is rarely possible to observe a distinct second round of nesting in species that normally nest only once. The colonial cliff swallow (Petrochelidon pyrrhonota) is a migratory songbird that has a relatively short breeding season in the western Great Plains, USA… Expand
Ectoparasitism shortens the breeding season in a colonial bird
TLDR
The results suggest that ectoparasitism shortens the cliff swallow's breeding season and probably prevents many individuals from multiple brooding, and when this constraint is removed, selection may rapidly favour late nesting. Expand
Multi-brooding and breeding season length in the reed warbler
TLDR
The causes and consequences of multi-brooding of the Eurasian reed warbler Acrocephalus scirpaceus and the results suggest that extending the breeding season at the individual level is a low value, low cost strategy. Expand
Parasites favour intermediate nestling mass and brood size in cliff swallows
A challenge of life‐history theory is to explain why animal body size does not continue to increase, given various advantages of larger size. In birds, body size of nestlings and the number ofExpand
Full lifetime perspectives on the costs and benefits of lay date variation in tree swallows.
TLDR
Examining the complete life histories of 867 female tree swallows breeding in Ithaca, New York, between 2002 and 2016 was able to clarify the relationship between timing of breeding and fitness and gain new insight into the sources of variability in this important life history trait. Expand
Wintering in Europe instead of Africa enhances juvenile survival in a long-distance migrant
Increased human-induced environmental changes and global warming alter bird migration timing and routes. Recently, many Holarctic species, including white storks, Ciconia ciconia, were reported toExpand
Challenges in the Identification and Interpretation of Phenological Shifts: Anthropogenic Influences on Adult Migration Timing in Salmonids
TLDR
Overall, it is challenging to attribute causation to phenological change, but salmon exemplify the many ways in which migration timing can change, including shifts due to climate and other processes. Expand
Increased reproductive investment associated with greater survival and longevity in Cassin's auklets
TLDR
It was found that high-quality individuals exhibited both increased reproductive effort and longevity, where heterogeneity in individual quality masked expected life-history trade-offs. Expand
Fluctuating survival selection explains variation in avian group size
TLDR
This study shows that changes in the direction and form of natural selection on colony size serve to maintain a wide range of group sizes and represents the first case, to the authors' knowledge, in which the advantages and disadvantages of different group sizes regularly fluctuate in a natural vertebrate population.

Fitness components associated with laying date in the cliff swallow
TLDR
Clutch size declined significantly across the season for both parasite-free (fumigated) and naturally infested nests, suggesting a strategic adjustment to reduce ectoparasitism by lowering the parasite carrying capacity per nest. Expand
Seasonal decline in reproductive performance varies with colony size in the fairy martin, Petrochelidon ariel
TLDR
The relationship between timing of breeding and reproductive performance (clutch size and nest success) both within and between variable sized colonies of fairy martins, Petrochelidon ariel is examined to highlight the importance of phenotype-related differences in settlement decisions and reproductiveperformance to an improved understanding of colonial breeding and variation in colony size.

What Determines the Rates of Double Brooding in the Western Bluebird?
TLDR
Both the length of the breeding season and the weather during that time influence rates of double brooding, and an individual's condition can affect whether or not it produces a second brood. Expand
Seasonal Decline in Reproductive Performance of Song Sparrows
Seasonal variation in reproductive success and nestling size were studied in a population of Song Sparrows (Melospiza melodia). I tested whether seasonal variation in reproductive success was due toExpand
COMPARATIVE REPRODUCTIVE BIOLOGY OF THREE SPECIES OF SWALLOWS IN A COMMON ENVIRONMENT
TLDR
Clutch size, number of broods/season, and fledging success did not vary among species, but overall, Tree Swallows grew the fastest and peak nestling mass was substantially higher in Cliff Swallows than the other species. Expand

TLDR
A harmful effect of relaying on female body mass at the end of the nestling period is revealed, which supports the view that timing-related energy constraints on breeding may be important causes of a seasonal decline in reproductive success at different latitudes. Expand
Adaptive significance of synchronized breeding in a colonial bird: a new hypothesis.
TLDR
It is proposed that social foraging plays an important role in maximizing the feeding efficiency in this species and that asynchronous breeding decreases the effectiveness of thissocial foraging, particularly in late nesters and among young, newly fledged birds. Expand
Occurrence and Implications of Double Brooding in a Southern Population of Tree Swallows
TLDR
If double brooding is as common elsewhere as it was in the study population, it could significantly alter estimates of seasonal or lifetime reproductive success in this widely studied bird. Expand
Group size and ectoparasitism affect daily survival probability in a colonial bird
TLDR
Daily survival of all birds increased with colony size for both parasite-free colonies and those under natural conditions, although the effect was stronger for adults at fumigated sites and for juveniles. Expand
Seasonal Decline in Reproductive Success of the Great Tit: Variation in Time or Quality?
TLDR
It is concluded that seasonal declines in reproductive success at the nestling stage and survival of adult females were caused by differences in quality between early and late breeders, and recruitment of fledglings into the breeding population and the occurrence of second clutches were causally related to the timing of breeding.
