How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Seabird demography and spatial distribution outside of the breeding season are poorly understood, and migratory stopover and staging sites represent important energetic bottlenecks during the avian annual cycle. We quantified hatch-year Roseate Tern (Sterna dougallii) weekly residency, weekly recruitment rate into the staging population, and derive...
Honest signaling mechanisms can function to appropriate care to hungry offspring and avoid misdirected care of unrelated offspring. Begging, the behavior by which offspring solicit food and parental care, may be an honest signaling mechanism for need, as well as association of parents and offspring. Roseate terns (Sterna dougallii) exhibit prolonge...
Buffer zones, calculated by flight‐initiation distance (FID), are often used to reduce anthropogenic disturbances to wildlife, but FID can vary significantly across life‐history stages. We examined the behavioral effect of potential natural (gulls and shorebirds) and anthropogenic (pedestrians) disturbance sources to staging roseate (Sterna dougall...
Although most conservation effort and research on terns has focused on breeding colonies, there is increasing awareness of the importance of staging, stopover and wintering areas. Cape Cod (Massachusetts, USA) is well known as a critically important staging area for the endangered Northwest Atlantic population of Roseate Terns (Sterna dougallii). L...
Juvenile prospecting, or exploratory behavior for gleaning information about areas or events, can have profound effects on the selection of future breeding habitat, particularly for birds with high site fidelity whose initial choice of breeding habitat could represent a lifetime investment in fitness. We present data from a 10-yr study of Piping Pl...
Avian research that involves potential disturbance to the study species may have unintended fitness consequences and could lead to biases in measurements of interest. The effects of band resighting on the behavior of mixed-species flocks of staging waterbirds were evaluated against recreational pedestrian activity that was expected to cause flushin...
Develop and optimize aerial survey design protocols and models for assessing seabird species abundance and distribution in the northern Gulf of Mexico region.
The goal of my Master's research is to investigate the potential role of disturbance in limiting the recovery of a federally endangered pelagic seabird, the Roseate Tern (Sterna dougallii). Mechanisms explored include its effects on survival and residency rates, site usage, and behavior/energetics.
