Grassland birds have experienced steeper population declines between 1966 and 2015 than any other bird group on the North American continent, and migratory grassland birds may face threats in all stages of their annual cycle. The grassland‐associated long‐billed curlew (Numenius americanus) is experiencing population declines in regional and local portions of their North American breeding range. The nesting period is an important portion of the annual cycle when curlews may face demographic rate limitations from a suite of threats including predators and anthropogenic disturbance. We compared nest sites to random sites within breeding territories to examine nest site …

Impacts Of Anthropogenic Waste On Tasmanian Pacific Gull (Larus Pacificus) Diet, Anne Bartlett
Independent Study Project (ISP) Collection
Plastic pollution is one of the foremost environmental issues that the world is currently experiencing. The effects of plastic pollution are great and range from leaching of hazardous chemicals into the environment to ingestion of plastic waste by wildlife, including seabirds. Due to the high rates of plastic consumption by seabirds, many recent studies have been performed to determine the biological impacts of plastic consumption on various seabird species. The Pacific Gull (Larus pacificus) is the world’s largest sea gull and the only gull endemic to Australia, yet very limited information exists on this species. This study examines the impacts …

We developed a Hidden Markov mark–recapture model (R package marked) to examine sex‐specific demography in Magellanic Penguins (Spheniscus magellanicus ). Our model was based on 33 yr of resightings at Punta Tombo, Argentina, where we banded ~44,000 chicks from 1983 to 2010. Because we sexed only 57% of individuals over their lifetime, we treated sex as an uncertain state in our model. Our goals were to provide insight into the population dynamics of this declining colony, to inform conservation of this species, and to highlight the importance of considering sex‐specific vital rates in demographic seabird studies. Like many other …
