Natal dispersal and first-year survival in a neotropical migratory songbird
… However, because first-year (i.e. 1-year-old) migratory passerines are thought to return to breed at great distances from their natal location, the factors that influence first-year survival have not been thoroughly investigated. To examine the factors that affect first-year survival, I …

Mechanisms underlying population dynamics of a migratory songbird in a fragmented forest
… implicated as a cause of long-term changes in migratory songbird populations. Some problems associated with fragmentation are generally considered edge effects (nest predation and cowbird brood parasitism), whereas others are attributed to fragment size and isolation (low pairing success, area …

An Experimental Study of Behavioral Responses to Nest Predation and Brood Parasitism in a Migratory Songbird
We expect birds to evolve life history traits that maximize lifetime reproductive success and that these traits will include behavioral responses to factors limiting reproductive success. These behavioral responses may be especially important for birds breeding in highly fragmented landscapes where …

An integrative approach to testing density effects in a migratory songbird, the Prothonotary Warbler (Protonotaria citrea)
… and physiology of a population of cavity-nesting songbirds, the Prothonotary Warbler (Protonotaria citrea), in southern Illinois, USA. From 2008-2011, I experimentally manipulated the availability of nest boxes by establishing two low-density and two high-density subplots on each of two 40 ha …

The Effects of Hackberry Psyllids on Refueling Migratory Songbirds and Autumnal Seed Rain
… abundant during autumn, a period of time when migratory songbirds are traveling from their breeding areas in temperate North America south to their winter ranges. These migrations are energetically taxing and many songbirds fuel their journey with resources like insects and fruits. I captured …

POPULATION DYNAMICS OF SPECIES RECOVERY: MULTISCALE DEMOGRAPHY IN RESTORED HABITATS
… restoration outcomes for a Nearctic-Neotropical migratory songbird, the Golden-winged Warbler (Vermivora chrysoptera). Over the past half-century, Golden-winged Warbler populations have declined, in part, due to the loss of early-successional breeding habitat. One strategy to address declines has …

Habitat selection and survival of juvenile black-capped vireos during the post-fledging period
Population declines of many species of songbirds have stimulated much research on breeding, migration, and wintering ecology. Until recently, the post-breeding season, the period from the completion of breeding and the onset of migration, has been overlooked. During this period, juvenile birds …
