Incubation behavior and dispersal patterns in the Mountain Plover (Charadrius montanus)
… of conservation concern. I also monitored incubation activity of Mountain Plovers in Montana using a combination of video monitoring and temperature data-logging. The rapid multi-clutch mating system of the Mountain Plover provides an interesting opportunity to examine sex-specific …

Incubation behavior, embryonic heart rate, and developmental variation within and among altricial bird species
The incubation period of an egg is a critical stage that has multiple implications in subsequent life stages, therefore understanding the processes within the egg during the incubation period are important for a broader understanding of avian development and life history strategies. I examined …

Consequences of avian parental incubation behavior for within-clutch variance in incubation temperature and offspring behavioral phenotypes
… early developmental environment is through egg incubation. Not only is incubation necessary for hatching success, but small changes of <1C in average incubation temperature have large effects on post-hatch offspring morphology and physiology. However, incubation is energetically costly and …

Transcriptional regulation of the prolactin gene in turkeys
… of egg production associated with the onset of incubation behavior. Prolactin (Prl) is involved in the induction and maintenance of incubation behavior in birds, and understanding the regulatory mechanism(s) of Prl gene expression will provide fundamental information to manipulate Prl production …

Behavioral ecology of wild turkeys
… site, and as a result our understanding of their incubation behavior is limited to a handful of studies. Lacking this important behavioral information, it remains unclear how incubation behavior among turkey hens influences reproductive success. Habitat use among hens during the reproductive …

Pituitary Prolactin Content of the Redwinged Blackbird at Pre-Breeding, Breeding and Post-Breeding Intervals
Environmental and physiological control of incubation behavior in wild and domesticated birds has been under investigation for the past thirty-five years. Most of the early literature deals with the non-passerines, specifically doves, pigeons and fowl. However, recent work has involved the order …

Urbanization's Effects on Avian Morphology, Hormones, and Behavior Across Ontogeny
… differences in the urban phenotype, mostly in behavior, phenology, physiology, and morphology. While knowledge of phenotypic shifts in urban wildlife is growing, understanding the particular ecological pressures driving these changes and the mechanisms leading to phenotypic change and …

Incubation temperature impacts growth, physiology and survival in nestlings of an open-cup nesting passerine
… Much less is known, however, about the role of incubation temperature in shaping the phenotype. Among species in which one or both parents incubate, there is the possibility that changes in incubation behavior on the part of the parent(s) can impact the developing offspring. The vast majority of …

Breeding Biology Of Chuck-Will's-Widows: Incubation, Brooding, And Provisioning Behavior And Characteristics Of Nest Sites
… nocturnal habits, little is known about their behavior, particularly their breeding and nesting behavior. Thus, my objectives were to: (1) quantify patterns of incubation behavior (e.g., on bouts vs. off bouts) and the respective roles of males and females, (2) quantify the brooding and …
