Demography of a declining Dunlin (<i>Calidris alpina arcticola</i>): influences on adult survival and mate fidelity of an Arctic-breeding migratory shorebird
… shorebird. Prior adult survival estimates (0.41– 0.60) appeared insufficient to maintain a stationary population, however, it was unclear if estimates were reflective of bias or a real survival signal. Additionally, C. a. arcticola mate fidelity has yet to be determined, and because …

Nesting Ecology Of Red-Headed Woodpeckers (Melanerpes Erythrocephalus) In Central Minnesota
… the nesting cycle in 2014 and 2015 and estimated nest success (from initiation to fledging) was 78.0% with logistic exposure modeling. Daily nest survival rate was higher for nests initiated earlier in the season and for nests in cavities in dead branches, as supported by lowest Akaike …

An Experimental Study of Behavioral Responses to Nest Predation and Brood Parasitism in a Migratory Songbird
… breeding success in the previous year. Approximately 80% of double-brooded males and females returned in the following year. Unsuccessful males with a successful neighboring pair of Prothonotary Warblers returned at a higher rate than those with unsuccessful neighbors. Territory fidelity tended …

A population biology of breeding redshanks (Tringa totanus L.)
… both sexes, of 0.77, and a population of approximately 200 pairs in 1.04km? Mate fidelity was very high, with 71% of surviving pairs remaining faithful. Nest site fidelity was extremely strong for faithful pairs and males with new mates, but significantly weaker for females with new mates. A …

Breeding biology, mating system and population dynamics of the Lesser Spotted Woodepcker (Picoides minor) : combining empirical and model investigations
… by deterioration in food supply. Moreover, mate fidelity was of benefit, since pairs composed of individuals that bred together the previous year started earlier with egg laying and obtained a higher reproductive success. Both sexes were involved in parental care, but the care was only …

Fitness Consequences of Clutch Size Decisions and Mate Change in Black Brant
… of reproductive effort (Chapter 2) and mate change (Chapters 3-5) in black brant geese (Branta bernicla nigricans, hereafter brant), an Arctic nesting goose species with precocial young. I used a 25 year (1990-2014) dataset collected at the Tutakoke River brant colony (TRC), in …

Demography and Behavior of Western Sandpipers (Calidris mauri) Breeding on the Yukon-Kuskokwim River Delta, Alaska
… Delta, Alaska (1998-2005). In chapter one, I estimated apparent annual survival (product of true survival and site fidelity) while correcting for the probability of encounter for 237 males and 296 females. Overall return rates (individual returned to the site in a subsequent season) were lower for …
