We present the first record of total leucism for the Clay-colored Thrush, Turdus grayi, and the fourth case of chromatic aberration for this species. From April 2019 to August 2020, we observed an adult individual characterized by a lack of pigmentation with completely white plumage and eyes of normal color. The locality of occurrence corresponds to the tropical humid forest of the Lancetilla Botanical Garden, 250 meters from the city of Tela, on the north coast of Honduras. Documenting these cases in the Neotropical region is important to better understand pigment abnormalities, and studies are necessary to evaluate the survival and reproductive success of birds that present a lack of pigmentation.

粘土色鹅口疮中的总白血病的第一个记录（灰眉鸟，Aves，Passeriformes，Turdidae）

我们介绍了粘土色画眉鸟，灰眉鸟的总白粉病的第一个记录，以及该物种的色差的第四例。从2019年4月到2020年8月，我们观察到一个成年人，其特征是缺乏色素沉着，全身呈白色羽毛，眼睛颜色正常。发生的地点与洪都拉斯北海岸的特拉市（Tela）250米的兰斯提拉植物园（Lancetilla Botanical Garden）的热带湿润森林相对应。记录新热带地区的这些病例对于更好地了解色素异常非常重要，并且有必要进行研究以评估缺乏色素沉着的鸟类的存活和生殖成功。
