“…Desertion has been defined as termination of care, by either one or both parents, before the offspring are capable of surviving independently (Fujioka 1989). This phenomenon has been reported in a variety of taxa including invertebrates, fish, amphibia, birds and mammals (Kleiman 1977;Blumer 1979;Forester 1979;Perrone and Zaret 1979;Wells 1981;Beissinger 1987;Ueda 1987;Nafus and Schreiner 1988;Diesel 1989;Kelly and Kennedy 1993). Desertion by either parent is particularly common in precocial birds such as in ratites, ducks and shorebirds (Lenington 1984;Bustnes and Erikstad 1991;Clutton-Brock 1991;P6ysfi 1992).…”

Female kentish plovers Charadrius alexandrinus typically desert their broods after the chicks hatch, i.e. 14 weeks before the chicks fledge or become independent. In this paper we investigate the costs and benefits of desertion for females. Desertion incurs a cost for females: following desertion chick survival in broods is lower (0.95 + 0.02 day -1) than before the female deserts (0.98 + 0.01 day-l). We investigated several possible causes for reduced brood survival by comparing characteristics of broods before and after desertion (controlling for differences in brood age). After desertion males increased the time they spent foraging and they tended to reduce time spent brooding chicks. Increased mortality of chicks may occur in deserted broods because following desertion (1) males spend less time alert in vigilance behaviour than before desertion, (2) they attend the chicks from greater distances, and (3) they show greater distraction display distances (in response to human intruders). Growth or development of chicks, measured by weight gain and tarsus length, was not different before and after desertion. Females gain two potential benefits from desertion: (1) they may remate and produce a second brood within the same breeding season or (2) they may enhance their probability of surviving to breed in a subsequent season. At least 27% of female kentish plovers that deserted remated and renested in the same season in this study. In contrast, we found no evidence that brood desertion increased the survival of females: there was no difference in local survival rate (return rate) for females deserting before or after 6 days brood age.These results clearly demonstrate that female kentish plovers that desert their offspring prior to fledging incur costs, but we suggest that there is a trade-off with the potential benefits gained by remating and making a second breeding attempt in the same season.

“…Finally, we examined the breeding success of adults attempting to rear more than one brood within a nesting season, and the long-term costs of polygamy either to survivorship as a result of increased reproductive effort (Lessells 1984, Jonsson & Alerstam 1990 or through a delay in initiating nesting the following year through delays in other activities in the intervening period (e.g. moult, Ueda 1987, Urano 1992.…”

Brood desertion and polygamous breeding in the Kentish Plover Charadrius alexandrinus

In the Kentish Plover Churudrius uhundrinus one of the adults, typically the female, deserts the brood when the chicks are a few days old. Once parental care is terminated, adults may initiate a second nesting attempt if sufficient time remains within the season.For these nests, individuals pair with different mates fiom those of the first nesting attempt, thus becoming sequentially polygamous. In a small population of Kentish Plovers in Fuente de Piedra lake (southern Spain), the duration of biparental care of broods was longer than in other localities. It also showed considerable variation between years that was evidently related to Gull-billed Tern Gelochelidon niloticu predation pressure on the chicks. There was year-to-year variation in the number of polygamous matings. Both the duration of the breeding season and nesting success in the first half of the season limited the occurrence of polygamy. Despite females deserting broods earlier than males, the interval between the first and second nesting of polyandrous females and polygynous males was similar. The interval was not affected by the body condition of females after the first nesting attempt, nor by problems related to egg formation ability, but was probably due to the availability of potential mates. More females than males initiated second nests, suggesting that polygamous opportunities were more limited for males than for females. In terms of delayed breeding, reduced survivorship or reduced breeding opportunities in years following polygamous breeding, polygamous individuals did not have greater costs than non-polygamous ones. Females with second nests did not seem to be selective in mate choice, mating with any available male. Mates for second nests may therefore be of lower quality than those for first nests, as judged by male plumage characteristics. Clutch sizes and egg characteristics of polyandrous females were similar in first and second nests. Nest success of second nests was only 40% of that of first ones, with nest desertion accounting for 60% of the losses. As the costs of polygamy are apparently low and as breeding success is very variable among years, polygamous breeding of the long-lived Kentish Plover may be an important breeding strategy with which to increase individual lifetime reproductive success.

“…Either negative or positive association between laying date and the desertion probability is expected based on the assumption of a seasonal decline in re-laying opportunities and seasonal deterioration of the offspring quality (Bauchau and Seinen 1997;Fernandez and Reboreda 2000;Rossmanith et al 2007). Such an association, in most cases with latelaid clutches being more often deserted than early-laid ones, have been found for example in the Collared Flycatcher, the Fan-tailed Warbler (Cisticola juncidis), the Greater Rhea (Rhea americana), the Sparrowhawk (Accipiter nisus) and the Song Sparrow (Melospiza melodia) (Cavalcanti 1981;Newton and Marquiss 1984;Ueda 1987;Wiggins et al 1994;Fernandez and Reboreda 2000). The lack of this relationship in the population under study may be explained by the fact that both mechanisms operate in the population, but because of their opposite effects they cancel out each other.…”

Nest desertion behaviour in relation to body condition and timing of breeding was studied in Great Tit (Parus major) females during two breeding seasons. Desertion, most likely unintentionally provoked by catching females during the incubation period, occurred at a very high rate with 41.2 and 25.6% of deserted first clutches in the two study years. The association between desertion probability, body condition (index calculated as residuals from the regression of body mass on tarsus length) and timing of breeding differed between the seasons with the highest probability of desertion among females in low condition laying early in the season in one year and females in low condition laying late in the season in the other year. Desertion probability was best predicted by body condition with females in low condition deserting at much higher rate than females in good condition. These results suggest that nest desertion by females subjected to disturbance during the early stage of the nesting cycle may be associated with the level of their body reserves, and that patterns of desertion in relation to body condition and timing of breeding may differ between years.Zusammenfassung Während zweier Brutperioden wurde bei weiblichen Kohlmeisen das Verlassen der Gelege im Zusammenhang mit ihrer körperlichen Verfassung und dem Zeitpunkt des Brütens untersucht. Das Verlassen, höchstwahrscheinlich unabsichtlich vom Fang der Weibchen während des Brütens ausgelöst, trat in den beiden Untersuchungsjahren mit hoher Rate auf: 41,2 und 25,6% Erstgelege wurden verlassen. Der Zusammenhang zwischen Verlassens-Wahrscheinlichkeit, körperlicher Verfassung (Index berechnet als Residuen einer Regression von Körpermasse und Tarsus-Länge) und Zeitpunkt des Brütens variierte zwischen den Jahreszeiten; die höchste VerlassensWahrscheinlichkeit gab es bei Weibchen in weniger guter Verfassung und früher Brutzeit in dem einen Jahr und Weibchen in nicht guter Verfassung und später Brutzeit in dem anderen Jahr. Die körperliche Verfassung als Prädiktor der Verlassens-Wahrscheinlichkeit stimmte am besten für Weibchen in nicht guter Verfassung, bei denen die Verlassens-Rate viel höher lag als bei Weibchen in gutem physischen Zustand. Diese Ergebnisse legen die Annahme nahe, dass das Verlassen der Gelege von im frühen Niststadium gestörten Weibchen mit dem Stand ihrer Körperreserven zusammenhängt und das Verlassen in Abhängigkeit von der körperlichen Verfassung und der Zeit des Brütens von Jahr zu Jahr unterschiedlich sein könnte.
