“…Moreover, there is evidence in mammals that GnRH 547 up-regulates its own receptors (Clayton, 1989). Therefore, if the priming effect of GnRH 548 26 on its own receptors persists until the next breeding season, the age-related advance in 549 laying date observed in many birds (Saether, 1990;Fowler, 1995) may be due, at least 550 in part, to previous experience with photostimulation and the associated exposure to 551 elevated GnRH levels. 552…”

In many vertebrates parental age is related to reproductive output with older individuals 25 often performing better (e.g., advanced timing, more offspring) than younger ones. First-26 year birds differ from older birds in that they lack previous experience with the 27 reproductively-stimulatory effects of long day lengths (photostimulation). The goal of this 28 study was to examine whether this age-related increase in reproductive output can be 29 attributed, at least in part, to previous experience with photostimulation in a 30 photoperiodic bird, the female house finch (Carpodacus mexicanus). Specifically, we 31 investigated whether previous experience with photostimulation influences the early 32 stages of reproductive development by quantifying plasma luteinizing hormone (LH), 33 plasma vitellogenin, ovarian follicle size, and immunoreactivity of hypothalamic 34 1 Prior Experience with Photostimulation Enhances Photo-Induced gonadotropin-releasing hormone (GnRH-I) and vasoactive intestinal polypeptide (VIP). 35By differentially manipulating photoperiod, we generated two groups of first-year female 36 finches: a photo-experienced group that had been through one photoperiodically-37 induced cycle of gonadal development and regression, and a photo-naïve group 38 exposed to long days since hatch. Both groups were then transferred from long to short 39 days for nine weeks, to ensure full photoperiodic responsiveness, and then 40 photostimulated for four weeks and exposed to conspecific or heterospecific male song 41 starting 90 minutes before sacrifice. Following photostimulation, although photo-42 experienced and photo-naïve groups exhibited similar surges in plasma LH 43 concentrations, circulating vitellogenin levels increased in photo-experienced, but not in 44 photo-naïve birds. After four weeks of photostimulation, egg yolk deposition was 45 observed in two of six photo-experienced birds but in none of the photo-naïve birds. 46 3 After four weeks of photostimulation and exposure to conspecific or heterospecific male 47 song, more GnRH-I-ir cells were seen in the septo-preoptic hypothalamus of photo-48 experienced than of photo-naïve birds. In contrast, there were no differences between 49 the photo-experienced and photo-naïve birds, irrespective of the song type they were 50 exposed to, in numbers of visible VIP-ir cells in the mediobasal hypothalamus. Our 51 results demonstrate that previous photo-experience enhances some of the early stages 52 of photo-induced reproductive development, and that the reproductive neuroendocrine 53 system of photo-experienced, photoperiodic birds is primed to respond rapidly to 54 reproductively-stimulatory environmental and social cues. 55

“…We found that pairs breeding earliest in a year were those that returned to breed across seasons. Most studies that have related pair-bond duration to breeding onset (reviewed in Fowler, 1995) have been conducted on long-lived species (e.g. procellarids, sulids, larids, spheniscids).…”

“…Studies of variability in breeding onset among individuals within a species have revealed a suite of proximate factors that accelerate or delay the timing of breeding in birds. Female traits such as nutritional state (Jones & Ward, 1976;Yom-Tov & Hilborn, 1981;Martin, 1987), age (Saether, 1990), breeding experience (Fowler, 1995), and competitive ability (O'Donald, 1980;Kelly & Van Horne, 1997) all have been shown to advance laying date in birds. The phenotypic or genotypic quality of male mates, as measured by ornamental traits such as song (Kroodsma, 1976;Wright & Cuthill, 1992) and courtship feeding (Nisbet, 1973), may also bring females into reproductive condition sooner during the year.…”

“…Characteristics of the male-female pair, such as the duration of the pair bond (in years), are also regarded as important determinants of breeding onset, with birds remaining paired together across seasons initiating breeding earlier than newly formed pairs (reviewed in Fowler, 1995). Under these circumstances, however, it is not always clear how males and females equally or differentially contribute to pair bonding and early breeding onset.…”

SummaryIn seasonally breeding birds, natural selection favors individualsthat begin breeding earlier in a year because they produce more or higher quality offspring than those that begin breeding later. Among the factors that in uence the timing of breeding, which include the age, health, competitive ability, or mate quality of individuals, is the longevity of the pair bond, with birds that remain mated across years initiating breeding earlier in the season than newly formed pairs. The behavioural interactions between pair members that may facilitate long-term pair bonding and early breeding onset have infrequently been studied, however. Here we report the relationship between male-female af liative behaviour, pair-bond duration, and breeding date in house nches (Carpodacus mexicanus), a short-lived, socially monogamous passerine species in which the duration of pair bonds is highly variable within and among seasons. Finches that initiated breeding earliest in the season were those that had bred with one another in previous years. Early breeding males from returning pairs maintained signi cantly closer contact with their mate during the rst egg-laying period of the year than did males from late-breeding, newly formed pairs. Similarly, early-breeding females from returning pairs followed their mate more closely in nest-vicinity ights during the fertile period than 3) Corresponding

“…[4,5]). Although many studies have been carried out to answer these questions, a large proportion of them have important limitations [6]. To understand the implications of partner choice and fidelity from an ecological and evolutionary perspective, it is fundamental to develop methods that incorporate the cumulative effect of pair bond on breeding output, while accounting for age effects of both sexes on survival and fertility, and for individual heterogeneity in breeding performance.…”

Better the devil you know: common terns stay with a previous partner although pair bond duration does not affect breeding output

In a monogamous species two partners contribute to the breeding process. We study pair formation as well as the effect of pair bond length and age on breeding performance, incorporating individual heterogeneity, based on a high-quality dataset of a long-lived seabird, the common tern ( Sterna hirundo ). To handle missing information and model the complicated processes driving reproduction, we use a hierarchical Bayesian model of the steps that lead to the number of fledglings, including processes at the individual and the pair level. The results show that the age of both partners is important for reproductive performance, with similar patterns for both sexes and individual heterogeneity in reproductive performance, but pair bond length is not. The terns are more likely to choose a former partner independent of the previous breeding outcome with that partner, which suggests a tendency to retain the partner chosen at the beginning of the breeding career.
