Dataset For: Incorporation of Deepwater Horizon oil in a terrestrial bird

We measured radiocarbon (14C) and stable carbon (13C) content in seaside sparrow (Ammodramus maritimus) feathers and crop contents collected in Bay Jimmy and Bay Sansbois, Louisiana, in August 2011. Lower 14C and 13C values in feathers and crop contents of birds from contaminated areas indicated incorporation of carbon from oil. Our results reveal a food-web link between oil exposure and a terrestrial ecosystem. This dataset supports the publication: Bonisoli-Alquati, A., Stouffer, P. C., Turner, R.
