“…Paralleling our results, breeding dispersal in black-legged kittiwakes increased the probability of non-breeding, since remating and nest site prospecting were time consuming (Danchin and Cam 2002). These results support the conclusion that dispersal seldom improves individual fitness in the short term by increasing subsequent breeding success (Clark and Shutler 1999;Shutler and Clark 2003;Schaub and von Hirschheydt 2009). Besides explanations based on potentially maladaptive conspecific attraction, this dispersal-induced breeding delay may also help explain why breeding dispersal is not increasing as a response to high breeding density, despite the potential reduction in nesting success at the highest densities indicated by our colony-level data (Fig.…”

“…While some studies have found that dispersing may improve subsequent breeding success (Hepp and Kennamer 1992;Forero et al 1999;Newton 2001;Calabuig et al 2008), negative results are more prevalent (Clark and Shutler 1999;Danchin and Cam 2002;Shutler and Clark 2003;Schaub and von Hirschheydt 2009). This leaves us with an apparent paradox: while we inherently assume that breeding dispersal is adaptive, it is often difficult to ascribe an adaptive function to the behaviour (Clark and Shutler 1999).…”

“…This leaves us with an apparent paradox: while we inherently assume that breeding dispersal is adaptive, it is often difficult to ascribe an adaptive function to the behaviour (Clark and Shutler 1999). Resolution of the paradox requires knowledge of the costs of dispersal, including lost site familiarity and potential reductions in reproductive success following dispersal (Anderson et al 1992;Danchin and Cam 2002;Ward and Weatherhead 2005), and these costs should be weighed against the expected benefits (Shutler and Clark 2003). Especially in long-lived species, potential benefits of dispersal may only become apparent in the years following dispersal (Ward and Weatherhead 2005).…”

Causes and consequences of fine-scale breeding dispersal in a female-philopatric species

The potentially confounded effects of factors affecting breeding dispersal have rarely been simultaneously examined. The consequences of breeding dispersal are even less studied, presenting a paradox: breeding dispersal seldom seems to improve breeding success, despite its presumed adaptiveness. We studied the causes and consequences of breeding dispersal in female-philopatric eiders (Somateria mollissima) in relation to the spatiotemporal predictability of nest success. Previous nest fate, breeding experience, and breeding density simultaneously affected breeding dispersal. Dispersal distances were longer among inexperienced breeders and after failed breeding. Individual dispersal distances decreased with increasing nest-site-specific breeding density, whereas island-specific nesting success peaked at intermediate densities. The fate of neighbouring nests ('public information') did not influence dispersal. Breeding dispersal was unrelated to subsequent hatching success, controlling for individual quality (body condition, breeding experience, previous nest fate), while it delayed hatch date, which is likely to impair reproductive success. This delay may result from the loss of acquired information of local breeding conditions, prolonging nest prospecting and establishment, also helping explain why breeding dispersal did not increase at high breeding densities, despite a potential reduction in nesting success. In long-lived species, however, dispersal-induced reductions in reproductive output in one season could be offset by improved parental survival prospects. Careful nest prospecting may be profitable, because overall nest success had a strong island-specific component but showed weak temporal variation, and successive individual nest fates were predictable between years. Once a safe nest site is found, females may breed at the same place successfully for many years.

“…above or below population average). Some experimental studies have found that breeding dispersal distances are not affected by previous breeding success (Shutler and Clark 2003), but we cannot give a definite answer to why especially F. hypoleuca females with a low breeding success would return near to their previous breeding site. We are not aware that this kind of ''lose-stay'' strategy is found in birds (cf.…”

The effects of sex, age and breeding success on breeding dispersal of pied flycatchers along a pollution gradient

et al. 2008

We modelled breeding dispersal of an insectivorous bird, the pied flycatcher (Ficedula hypoleuca) around a point source of heavy metals (a copper smelter). We tested for the effects of sex, age, breeding success and environmental pollution on breeding dispersal distances of F. hypoleuca females and males. Unlike many earlier studies on breeding dispersal, we took into account distance-dependent sampling bias by including in our model the recapture probabilities at different distances from the site of origin. Our results show that F. hypoleuca females disperse much farther (on average 7.9 km) from their breeding sites than what was previously thought. In contrast, males only disperse short distances (on average 190 m). Breeding success affected female breeding dispersal distances depending on female age: young females moved on average 8 km from their previous breeding place irrespective of their breeding success, while old females only seemed to move this far when their fledgling production was good. Females successful in their breeding dispersed as far as less successful females, or, among old birds, even farther. Females which dispersed long distances produced more fledglings after the movement than those staying near their previous breeding site. Degree of environmental pollution had no effect on female or male breeding dispersal distances. A polluted and unproductive environment does not seem to stimulate F. hypoleuca parents to move to more profitable territories.

“…In particular, workload and stress during breeding may increase individual susceptibility to illness and predation, or delay migration, which might decrease adult survival and thus also return rate (Oppliger et al 1997;Newton 2010). Returning to a formerly occupied location might be related to better knowledge of resource distribution (Rappole and Jones 2002), awareness of predation risk (Shutler and Clark 2003) and, namely for males, greater chances of keeping a good-quality territory and mate (Pärt 1994). In contrast, moving to a new site may be driven by avoiding competition, leaving unfavourable conditions, finding new resources (Bowler and Benton 2005) or enhancing female chances to find a male with a high-quality territory (Greenwood and Harvey 1982).…”

Returning to a breeding site and decision where to breed belong to the key life-history traits, especially in migratory birds. Yet, we still lack knowledge about the drivers of adult return rates and breeding dispersal distances in populations under pressure of brood parasitism. We explored these issues in a trans-Saharan migratory passerine, the great reed warbler (Acrocephalus arundinaceus), in a population parasitized by the common cuckoo (Cuculus canorus)-an evicting brood parasite. In 2008-2012, a total of 563 great reed warblers were colour-marked and 185 of them were reencountered 303 times in a year following their breeding at a fishpond area in the Czech Republic. We tested how brood parasitism and host breeding parameters in 1 year affect host return rate and dispersal distances in a following year. Return rate was lower in females fledging a cuckoo and in both sexes that failed to produce any offspring than in birds that fledged own chicks in the preceding year. Individual brood parasitism had a negative effect on the probability of female returning, but this relationship disappeared when excluding females fledging cuckoos. Although return rates did not differ between females that rejected and those that accepted cuckoo eggs, rejecter females dispersed less than acceptors. We conclude that brood parasitism and fostering the parasite might be negatively related to host female survival. The other breeding conditions might rather be related to the decision where to breed in the future. Establishing new long-term studies monitoring parasitized populations might open up avenues for future research.
