Laysan Albatross chicks from Midway Atoll, North Pacific Ocean, were assessed in 1994 and 1995 for impacts of plastic ingestion. Masses and incidence of plastic in chicks were compared between birds found dead of "natural causes" and those injured by motor vehicles. Naturally killed Laysan Albatross chicks had significantly greater masses of plastic in their proventriculi and gizzards and had significantly lighter body masses and lower fat indices than injured but otherwise healthy chicks. Ingested plastic probably does not cause significant direct mortality in Laysan Albatross chicks, but likely causes physiological stress as a result of satiation and mechanical blockages.
