Ingestion of plastic debris by Laysan Albatrosses and Wedge-tailed Shearwaters in the Hawaiian Islands

Occurrence of plastic particles in procellariiforms, south of São Paulo state (Brazil)

“…Many studies have already reported the presence of plastic particles in the stomachof seabirds (Morris, 1980;Fry et al, 1987;Furness 1994;Robards et al, 1995), clearly identifying the problem. The effects of the plastic particles ingested by the seabirds were also studied by Van Franeker (1985), who found that in some cases, the stomachs suffered ulcers and the intestines were obstructed, mainly when large fragments were ingested (Fry et al, 1987;Boersma and Groom, 1993).…”

Other studies indicated that plastic particles interfered with the seabird's digestion.…”

Regional differences in plastic ingestion among Southern Ocean fur seals and albatrosses

“…Among the albatrosses (Diomedeidae), the incidence of ingested plastic is generally quite low with the exception of the two common North Pacific species (Laysan Phoebastria immutabilis and Black-footed P. nigripes albatrosses), which have high incidence of ingestion (Gray et al, 2012), particularly among their chicks (Fry et al, 1987). However, a recent paper by Jiménez et al (2015) reported that 26% of Diomedea albatrosses killed by fishing gear off the east coast of South America contained plastic or other marine debris.…”
