“…A large fraction of the recoveries came from hunting on Engure Marsh following the breeding season. More detailed information on the study site, field methods, and breeding populations is provided elsewhere (Blums et al 1996, Viksne 2000. Previous analyses provided evidence of differences in annual survival between SY and ASY pochard females.…”

“…It would have been possible to write the above linear-logistic relationships with year-specific intercepts, permitting year-to-year variation in survival. However, our previous work (Blums et al 1996(Blums et al , 2002b led to the inference that full time-specific variation in survival was not needed to model these data. The model sets for each species included models with survival being a function of each covariate separately and with both linear and quadratic terms.…”

“…Newly hatched ducklings were marked individually using plasticine-filled leg bands (Blums et al1994) shortly before nest exodus. More detailed information on the study site, field methods, and breeding populations is provided elsewhere (Blums et al 1996;Blums et al 2003;Viksne 2000). …”

“…Here, we use path analysis to test hypotheses about causes of variation in LRS of individually marked females and their offspring in three species of European ducks (tufted duck, Aythya fuligula; common pochard, Aythya ferina, hereafter pochard; northern shoveler, Anas clypeata, hereafter shoveler) with varying body size, age at first breeding, timing of nesting, annual survival and incidence of brood parasitism (Blums et al 1996(Blums et al , 1997(Blums et al , 2002aDugger and Blums 2001). Because of our ability to band large numbers of day-old ducklings (Blums et al 1994), we were able to take advantage of band returns from hunter-shot birds to obtain more complete estimates of LRS.…”

“…Vital rates have been studied in European ducks, too. For example, age-specific survival in females of the northern shoveler A. clypeata, the common pochard Aythya ferina and the tufted duck Aythya fuligula were investigated in Latvia (Blums et al 1996), and ageand sex-specific survival in Eurasian teal Anas crecca was studied in Britain (Gitay et al 1990). Survival rates in European mallards have been reported in national bird ringing recovery atlases (e.g.…”
