White-rumped Robin

The White-rumped Robin, scientifically known as Peneothello bimaculata, is a diminutive songbird with a striking contrast in its plumage. Adults typically measure between 13 to 14 centimeters in length, cloaked predominantly in black feathers. A distinctive white rump and upper tail coverts set this bird apart, along with white patches adorning the sides of its breast. The abdomen presents a white hue in the nominate subspecies, while in the subspecies vicarius, it is black with white mottling. Females bear a close resemblance to males but are discernible by the brown tinges in their black feathers. Both sexes have black bills and feet, and their eyes are a deep, dark brown.
