Article
Heidi E. J. Vliet, Auteur ; Bridget J. M. Stutchbury, AuteurRadiotelemetry is an essential method for studying the movements and survival of cryptic grassland bird fledglings. There is mixed evidence on the effects of wearing radio-transmitters for passerines, with negative consequences probably under-re[...]
Article
Bridget J. M. Stutchbury, Auteur ; Christy A. Morrissey, Auteur ; Margaret L. Eng, AuteurBirds that travel long distances between their wintering and breeding grounds may be particularly susceptible to neurotoxic insecticides, but the influence of insecticides on migration ability is poorly understood. Following acute exposure to tw[...]
Article
Emily A. McKinnon, Auteur ; T. Kurt Kyser, Auteur ; Bridget J. M. Stutchbury, AuteurMany migratory songbirds switch from a primarily insectivorous diet during the breeding season to either a mixed diet or fruit diet during the non-breeding season. However, for species with mixed diets, arthropods may be superior food items beca[...]
Article
Lance G. Woolaver, Auteur ; Rina K. Nichols, Auteur ; Eugene S. Morton, Auteur ; Bridget J. M. Stutchbury, AuteurRidgway's Hawk Buteo ridgwayi is a Critically Endangered forest raptor endemic to the island of Hispaniola in the Caribbean. The species is currently limited to a small area on the north-east coast of the island, with fewer than 110 pairs remain[...]
Article
Ioana Chiver, Auteur ; Bridget J. M. Stutchbury, Auteur ; Eugene S. Morton, AuteurRecent studies of tropical birds with year-round territoriality indicate that song rate is relatively low year-round in association with lower seasonality and relatively stable social environment over the year. We examined seasonal variation in [...]
Article
Bridget J. M. Stutchbury, Auteur ; Eugene S. Morton, Auteur ; Bonnie Woolfenden, AuteurLittle is known about the genetic mating systems of tropical passerines and how they vary among species. We studied the Lesser Elaenia (Elaenia chiriquensis) and the Yellow-bellied Elaenia (E. flavogaster) near Gamboa, Panama. These species bree[...]

Lance G. Woolaver, Auteur ; Rina K. Nichols, Auteur ; Eugene S. Morton, Auteur ; Bridget J. M. Stutchbury, AuteurRidgway's Hawks (Buteo ridgwayi) are critically endangered forest raptors endemic to the Caribbean island of Hispaniola, with approximate to 100 pairs remaining in the world. The species is ecologically little known yet such studies are importan[...]
Article
Paul H. Klatt, Auteur ; Bridget J. M. Stutchbury, Auteur ; Melissa L. Evans, AuteurIncubation feeding, where males feed their mates, is a common behavior in birds and may improve female condition, nest attentiveness, and nesting success. We used behavioral observations and a temporary mate removal experiment to test the female[...]
Article
Elizabeth A. Gow, Auteur ; Tyler W. Done, Auteur ; Bridget J. M. Stutchbury, AuteurRadio-tags are commonly used in studies of avian behavior and ecology, even though many studies have revealed negative impacts of radio-tags. Other studies of songbirds have revealed no negative effects of radio-tags on parental care, nesting su[...]
Article
Ioana Chiver, Auteur ; Bridget J. M. Stutchbury, Auteur ; Eugene S. Morton, AuteurTestosterone is important in mediating investment in competing activities such as territoriality, parental care, and maintenance behavior. Most studies of testosterone function have focused on temperate species and less is known about the role o[...]
Article
Ross J. Kresnik, Auteur ; Bridget J. M. Stutchbury, AuteurFor long-distance migrants, territoriality and prey biomass during the non-breeding season have been linked to body condition that can carry over to affect spring migration and breeding events. For Ovenbirds (Seiurus aurocapilla), studies in Jam[...]
Article
Melissa L. Evans, Auteur ; Bonnie E. Woolfenden, Auteur ; Lyle Friesen, Auteur ; Bridget J. M. Stutchbury, AuteurThe application of molecular tools to studies of avian mating systems has revealed that most songbird species engage in extra-pair matings. However, little is known about the possible effects of habitat fragmentation on extra-pair mating systems[...]
