The population of Flesh-footed Shearwaters, Puffinus carneipes, on Lord Howe Island, Australia, has decreased over recent decades. Known threats include long-line fishing and loss of nesting habitat. The recent occurrence of plastic debris in breeding colonies has raised concerns that plastic ingestion also may be contributing to the decline of this species. In this paper we investigate the extent of plastic ingestion by Flesh-footed and Wedge-tailed shearwaters, Puffinus pacificus, on Lord Howe Island. The remains offailed Flesh-footed Shearwater fledglings contained substantial quantities of plastics: up to 37 cm3, equivalent to at least 31% of proventricular capacity. Road-killed adults (n=21) had no plastic in their proventriculus. Proventricular contents of near-fledged birds, obtained by non-lethal means, showed that 79% of Flesh-footed Shearwaters and 43% of Wedge-tailed Shearwaters contained plastics, in volumes of up to 18.0 cm3 and 2.8 cm3, respectively.
Plastic loads were significantly less in Wedge-tailed Shearwaters, the difference possibly due to different densities of plastic within
the foraging locations of each species. The impact of plastic ingestion on the survival of Flesh-footed Shearwater chicks and fledglings, and the consequent impacts on the demography of the population are unknown and warrant further investigation.

The Royal Society of Tasmania acknowledges, with deep respect, the traditional owners of this land, and the ongoing custodianship of the Aboriginal people of Tasmania. The Society pays respect to Elders past, present and emerging. We acknowledge that Tasmanian Aboriginal Peoples have survived severe and unjust impacts resulting from invasion and dispossession of their Country. As an institution dedicated to the advancement of knowledge, the Royal Society of Tasmania recognises Aboriginal cultural knowledge and practices and seeks to respect and honour these traditions and the deep understanding they represent.
On 15 February 2021, the Royal Society of Tasmania offered a formal Apology to the Tasmanian Aboriginal people.
