A free-ranging California condor (Gymnogyps californianus) presented severely dehydrated, unable to stand, very weak, and with a distended crop. Toxicologic analysis revealed an elevated blood lead level of 291.4 microg/ ml. There was no evidence of lead exposure on radiographs. The condor was treated with chelating agents and intensive supportive care. Over a period of 10 days, a majority of its clinical signs improved, and lead levels dropped to near normal. However, the condor was left with a severe, persistent crop stasis and malnutrition. An esophagostomy tube, and later an ingluviostomy tube, were placed and maintained for a period of 1 mo. The condor was managed with continuous infusion feeding. After the feeding tube was removed, the condor was managed with small amounts of soft food orally. After 10 wk of treatment, the crop returned to normal function.
一只自由放养的加州兀鹫（加州神鹫，Gymnogyps californianus）出现严重脱水、无法站立、极度虚弱且嗉囊扩张的症状。毒理学分析显示其血铅水平升高至291.4微克/毫升。X光片上没有铅暴露的迹象。这只兀鹫接受了螯合剂治疗和强化支持治疗。在10天的时间里，它的大部分临床症状有所改善，铅水平降至接近正常。然而，这只兀鹫仍存在严重的、持续性的嗉囊停滞和营养不良问题。放置了一根食管造口管，后来又放置了一根嗉囊造口管，并维持了1个月。通过持续输注喂养来管理这只兀鹫。拔除喂养管后，给这只兀鹫口服少量软食进行管理。经过10周的治疗，嗉囊恢复了正常功能。
