Sturnella Neglecta

The nesting ecology of western meadowlarks (Sturnella neglecta) in southern Manitoba is strongly influenced by the timing of breeding. Physical characteristics of nests change, apparently in response to seasonally altered thermal demands. The largest eggs and the largest clutches are produced in the middle portion of the breeding season, and nests initiated at that time produce the greatest number of young. Nevertheless, nesting productivity is highest for females that begin nesting earlier in the season and that can therefore renest if their initial attempt fails. Females breeding with already-mated males have, on average, as high a reproductive success as do primary females. Nevertheless, nestlings of secondary females frequently starve if they do not receive a male's parental care. Asynchronous hatching and facultative brood reduction may decrease the total losses incurred through nestling starvation, and may be adaptations that allow successful polygyny in this species. Aggressive interactions between resident and unmated females may protect a primary female's "preferred" status and may affect a male's ability to breed bigamously.

Abstract Theoretical questions and conservation concerns have prompted numerous, intensive studies of songbird nesting ecology. Such studies use several techniques (flushing, capture, and blood sampling) that have the potential to negatively affect reproduction, survival, and site fidelity. Although studies have examined the effects of those techniques on avian reproduction and survival, the effect on the return rate of breeding songbirds has not been researched. We used data from a 28-year demographic study to investigate the possible effect of those three common research practices on the return rate of female Wood Thrushes (Hylocichla mustelina). We also tested reproductive success and age as predictors of return because they have been shown to influence site fidelity. Number of successful nests in a breeding season was the variable that best predicted return the following year. None of the research practices negatively affected return rate. That pattern held even among yearlings with zero production, a group that should be the most easily disturbed. We also show that using all years of return for site-faithful birds as observations (i.e. repeated sampling) inflates the estimated return rate.
