“…Poor reproductive performance of captive animals after release can also be caused by low habitat quality at the release site (Tweed et al 2006, Martínez-Abraín et al 2011, White et al 2012, and management of predators can play a significant role in improving habitat quality (Hegg et al 2012). During our study, the Monterey Bay area had active habitat and predator management programs and a population monitoring program that allowed managers to identify limiting factors and develop management actions.…”

“…juveniles fledged per year per male). Female snowy plovers typically do not rear chicks (Warriner et al 1986, Page et al 2009) and so would be less affected by behavioral deficits from the captive environment that may affect chick rearing, explaining why fledging success of nesting attempts involving captive females was unaffected.Poor reproductive performance of captive animals after release can also be caused by low habitat quality at the release site (Tweed et al 2006, Martínez-Abraín et al 2011, White et al 2012, and management of predators can play a significant role in improving habitat quality (Hegg et al 2012).

Captive-breeding and -rearing programs have been widely used for the conservation and recovery of imperiled species, and the success of such programs should be rigorously evaluated. In this study, we assessed the success of captive-rearing for a threatened shorebird, the snowy plover Charadrius nivosus, by comparing the survival and reproductive success of captivereared and wild-reared individuals on the central California coast from 2001 to 2010. We used mark-recapture analysis, implemented in the program MARK, to estimate apparent annual survival (ϕ) and encounter occasion detection probability (p) from capture and sighting data of marked plovers. We compared 3 measures of reproductive success (hatch rate, fledge rate and juveniles fledged per year) using stratified randomization tests based on individual breeding histories where captive-and wild-reared plovers were matched for age, sex and year. Captive-and wild-reared snowy plovers had similar apparent survival and reproductive rates and paired with mates of similar age in their first breeding year. The only exception was that captive males after their first breeding year had lower fledging rates than males from the overall population, but this did not affect the annual productivity rate. We conclude that releasing captive-reared individuals is a valuable part of ongoing efforts to restore the snowy plover population in California, and is also useful in cases where plover nests may need to be salvaged to protect them from oil contamination or other catastrophic events.KEY WORDS: Shorebird · Snowy plover · Captive-rearing · Survival · Reproduction 22: 85-94, 2013 Bart et al. 2007). Two plover species are listed under the United States Endangered Species Act, the piping plover Charadrius melodus and the snowy plover Charadrius nivosus; C. nivosus was formerly treated as a conspecific of C. alexandrinus (Chesser et al. 2011), but the World Conservation Union (IUCN 2012) has not yet accepted this change or designated status for C. nivosus. Both the piping and snowy plover have recovery plans recommending captive-rearing programs to support conservation efforts (USFWS 2003(USFWS , 2007. Plovers are ideal candidates for captiverearing programs because their offspring develop rapidly and have limited need of parental care.

Captive-rearing methods developed with killdeer Charadrius vociferus chicks (Powell & Cuthbert 1993, Powell et al. 1997 were applied to the Great Lakes population of the piping plover, but a subsequent analysis of this program found that the captive plovers had significantly lower apparent survival rates and breeding success than wild plovers (Roche et al. 2008). Similarly, Goossen et al. (2011) reported significantly lower return rates for captive versus wild piping plovers in Saska...

Birds have been bred in captivity since the dawn of civilization. In the nineteenth century, breeding rare and exotic animals for the menageries of royalty and aristocrats transitioned to the formation of public zoological gardens and natural history museums. With industrialization and human population expansion, some bird species became rare or disappeared entirely. Once the magnitude of the destructive forces of humans became evident, concerted efforts were initiated to restore depleted bird populations by using, among other techniques, captive breeding. In this article, I explore the evolution of avian conservation breeding programs and evaluate how this historical review informs our outlook for addressing the current extinction crisis.

“…Therefore, the information in this study refers to certain types of small predators (e.g., birds, small mammals, and lizards), which are very important in the study area (Castilla and Martínez, in press) and for the red-legged partridge in Spain (Herranz 2000;Castilla and Rodríguez 2002). In other studies small predators such as rats have been identified as the major cause of nest mortality (Tweed et al 2006).…”

Understanding whether egg failure occurs more frequently during laying or during incubation is important for determining the most vulnerable period of the egg phase in bird species with long laying and incubation periods. However, most studies compare nest failure during the egg stage and the hatchling stage. In this study we examined whether egg failure was higher during the laying period and early development than during the final stages of development in a population of red-legged partridge (Alectoris rufa) from northeast Spain. We collected 216 abandoned eggs in the field. Only 12% (n = 26) of the eggs were sufficiently intact to enable direct assessment of developmental stage, showing that 81% of 26 eggs were lost during early stages. The majority of eggs were depredated (n = 154, 71%), as evidenced by an opening hole. To take advantage of information contained in these eggs, we propose a simple method to assess their developmental stage by measuring the size of the opening of their hole. Based on this method, we estimated that the proportion of eggs lost during early stages ranged from 72 to 83%. We validated this result of a high percentage of egg failure during early developmental stages with a larger experimental sample. Nest losses in the partridge are higher during the laying period or early development. This result is important in that the direction of conservation efforts and their seasonal application should be adjusted to account for the most important factors affecting egg failure.
