摘要

黑色羽毛中的棕色像差是由鸟类真黑素的逐渐减少所定义的。本文描述了在印度拉贾斯坦邦Shokliya村的农业景观中观察到的印度斑椋鸟(Gracupica contra)的棕色畸变羽毛。观察到的个体在该物种通常是黑色的羽毛的所有区域都表现出褐色，包括头部，翅膀羽毛和尾羽。然而，没有色素沉着的羽毛仍然是白色的，不受影响。遗传和饮食因素被认为是造成鸟类这种异常的主要因素，但需要更多的研究来确定确切的原因。

First record of brown plumage aberration in Indian Pied Starling (Gracupica contra) from India

Abstract Brown aberration in black plumage is defined by the progressive reduction of eumelanin in birds. The present report describes an observation of plumage with brown aberration in Indian Pied Starling (Gracupica contra) from the agricultural landscape of Shokliya village, Rajasthan, India. The observed individual exhibited browning in all the areas of the plumage that are normally black in this species, including the head, wing feathers, and tail feathers. However, feathers with no pigmentation remained white and unaffected. Genetic and dietary factors are thought to be major factors responsible for such aberrations in birds, but more research is needed to determine the exact reasons.
