Petroica traversi
The Black Robin (Petroica traversi) is a diminutive, entirely black passerine endemic to the remote Chatham Islands of New Zealand, measuring approximately 15 cm (6 inches) in length and weighing a mere 20-25 grams. Its plumage is uniformly sooty black, extending to its dark bill, legs, and eyes, offering no distinct field marks other than its monochromatic appearance, making it unmistakable within its severely restricted range. Taxonomically, it belongs to the Australasian robin family Petro...
This species primarily inhabits dense, regenerating broadleaf forest and coastal scrubland, typically found at low elevations on small offshore islands. It favors areas with a thick understory and deep leaf litter crucial for foraging.
The Black Robin is primarily insectivorous, feeding on a wide array of invertebrates including beetles, spiders, crickets, caterpillars, and other small arthropods. It mainly forages by gleaning prey from the forest floor and low branches.
