Between January 1988 and February 1989, gizzards were collected from 1155 birds from the groups; Anatidae, Charadriidae, Scolopacidae and Rallidae, shot in the Camargue, and examined for the presence of ingested lead shot. Shot was found in nine out of ten Anatidae species, three of 15 Scolopacidae species and all of three Rallidae species. Twenty-seven per cent of Anatidae sampled had ingested shot, 13.8% had one shot present and 6.3% had more than five. Shot ingestion levels ranged from 3-60% of birds examined according to species. The incidence of shot ingestion did not appear to vary seasonally. In Anatidae, a strong interspecific relationship was found between the grit size ingested and susceptibility to ingest shot (r = 0.94). In Scolopacidae, shot ingestion may have been related to grit size ingested, feeding method and bill length. The levels of shot ingestion presented are for most species higher than have been reported elsewhere in the world. This may result from the absence of grit and presence of high shot densities in Camargue marshes.
1988年1月至1989年2月期间，从在卡马尔格射杀的1155只鸟类（包括鸭科、鹬科、鸻科和秧鸡科）身上采集砂囊，并检查其中是否含有摄入的铅弹。在10种鸭科鸟类中的9种、15种鹬科鸟类中的3种以及3种秧鸡科鸟类的所有个体中均发现了铅弹。所采样的鸭科鸟类中有27%摄入了铅弹，13.8%体内有一颗铅弹，6.3%体内有超过五颗铅弹。根据物种不同，摄入铅弹的鸟类比例在3%至60%之间。铅弹摄入的发生率似乎没有季节性变化。在鸭科中，发现摄入的沙砾大小与摄入铅弹的易感性之间存在很强的种间关系（r = 0.94）。在鹬科中，铅弹摄入可能与摄入的沙砾大小、觅食方式和喙长有关。所呈现的铅弹摄入水平在大多数物种中高于世界其他地方所报道的水平。这可能是由于卡马尔格沼泽地缺乏沙砾且铅弹密度高所致。
