“…We focused solely on near-term, acute mortality from the Deepwater Horizon spill, even though observations of oiled birds continued for at least 1 yr (Henkel et al 2012). We did not include estimates for indirect (Velando et al 2005) or chronic population effects (Irons et al 2000), either of which can increase the avian mortality (Pérez et al 2008).…”

“…From 20 April to 15 July, >636 million liters (4 million barrels) of oil spilled and contaminated more than 1100 km of coastline, primarily in Louisiana (Camilli et al , Chen and Denison ). As a result, oil carbon entered the marine food web (i.e., plankton, Graham et al ; small fish, Whitehead et al ) and a wide range of marine aquatic invertebrates, fish, birds, and mammals were exposed to the oil (Belanger et al , Henkel et al ). Because the oil spill occurred during the breeding season for many colonial‐nesting seabirds, some breeding adults were also contaminated (United States Fish and Wildlife Service [USFWS] ).…”

ABSTRACT. Marine oil spills may have extensive and deleterious effects on coastal waterbirds, but pre-spill data sets are often not available for making comparisons of demographics to the period following a spill. The 2010 Deepwater Horizon oil spill allowed us to compare Brown Pelican (Pelecanus occidentalis) demographics during pre-and post-spill years. We banded 1114 pelicans on Louisiana barrier islands from 2007 to 2009, tracked their distribution via band re-sighting surveys from 2008 to 2011, and conducted age-structure surveys. Across Louisiana coastal islands in 2011, we detected 7% of pelicans that had been oiled during the 2010 spill and released following rehabilitation. Similarly, 6% of pelicans (not oiled) banded at the same release site in 2007 were observed across coastal islands 1 yr after banding. We observed variation in proportions of pelicans that were 1, 2, and 3 or more years old among years (2008)(2009)(2010)(2011) and across islands, but little variation could readily be assigned to spill-related mortality. These Brown Pelican demographic trends one year following the Deepwater Horizon oil spill are contrary to other assessments of the impacts of oil contamination on marine birds. However, additional research is required to evaluate potential long-term population trends. RESUMEN. Las tendencias demográficas del Pelicano pardo, antes y después del derrame de petróleo Deepwater HorizonLos derrames de petróleo en el mar pueden tener amplios y efectos perjudiciales sobre las aves acuáticas en las zonas costeras, pero frecuentemente los conjuntos de datos que se refieren al tiempo antes del derrame no están disponibles para hacer comparaciones demográficas con el periodo que sigue el derrame. En el 2010, el derrame de petróleo Deepwater Horizon nos ha permitido comparar la demografía del Pelicano pardo (Pelecanus occidentalis) durante los años, antes y después, del derrame. Entre el 2007 al 2009, colocamos anillos en 1114 pelicanos en las islas de barrera en Luisiana. Luego hemos rastreado la distribución de estos pelicanos a través de re-estudios de avistamiento desde el 2008 al 2011, y realizamos encuestas demográficas sobre la estructura de la edad. En las islas costeras de Luisiana en el 2011, detectamos el 7% de pelicanos que habían sido empetrolados durante el derrame en el 2010, pero que fueron llevados a rehabilitación y liberados cuando terminaron su recuperación. Del mismo modo, el 6% de los pelicanos (no empetrolados) que fueron anillados en el mismo lugar de liberación (en el 2007) fueron observados en las islas costeras, un año después de ser anillados. Observamos variaciones en los porcentajes de pelicanos que tenían uno, dos, tres o más años de edad, entre los anos (2008 -2011) y a través de las islas. Poca variación podría ser asignada a la mortalidad relacionada con el derrame de petróleo. Estos estudios demográficos sobre el Pelicano pardo, hechos un año después del derrame de petróleo Deepwater Horizon, son contrarias a otras evaluaciones sobre los impactos de la contaminaci...

“…Thus, it would be presumed that birds suffering from oil-induced anemia would exhibit a reduction in the ability to sustain flight. In addition to flight ability, Heinz body anemia also adversely affects reproductive success, and immune function (Henkel et al, 2012;Leighton, 1993;Briggs et al, 1997).…”

A B S T R A C TThe Deepwater Horizon oil spill released 134 million gallons of crude oil into the Gulf of Mexico making it the largest oil spill in US history and exposing fish, birds, and marine mammals throughout the Gulf of Mexico to its toxicity. Fish eating waterbirds such as the double-crested cormorant (Phalacrocorax auritus) were exposed to the oil both by direct contact with the oil and orally through preening and the ingestion of contaminated fish. This study investigated the effects of orally ingestedMC252 oil-contaminated live fish food by double-crested cormorants on oxidative stress. Total, reduced, and oxidized glutathione levels, superoxide dismutase and glutathione peroxidase activities, total antioxidant capacity and lipid peroxidation were assessed in the liver tissues of control and treated cormorants. The results suggest that ingestion of the oil-contaminated fish resulted in significant increase in oxidative stress in the liver tissues of these birds. The oil-induced increase in oxidative stress could have detrimental impacts on the bird's life-history.
