During histological and physiological investigations of black vultures (Coragyps atratus) dissection revealed the presence of an "organ", the supracloacal chromolipoid body, which has no counterpart among other warm blooded animals. The organ occurs in both sexes and in birds of different ages. It is located in the median sagittal plane dorsal to the cloaca. It is enveloped by a smooth muscle-connective tissue capsule and has a rich blood supply. The supracloacal body is yellow-brown in color being composed chiefly of islands of pigment cells.Histochemically, the pigment is a chromolipoid as defined by Ciaccio.
在对黑兀鹫（美洲黑鹫）进行组织学和生理学研究期间，解剖发现了一个“器官”，即泄殖腔上色素脂质体，在其他温血动物中没有类似物。该器官在两性和不同年龄的鸟类中均有出现。它位于泄殖腔背侧的正中矢状平面内。它被一层平滑肌 - 结缔组织包膜包裹，血液供应丰富。泄殖腔上体呈黄棕色，主要由色素细胞岛组成。组织化学上，这种色素是恰乔所定义的色素脂质。
