The Tagula shrikethrush (Colluricincla discolor) is a species of bird in the family Pachycephalidae.
This species was formerly considered a conspecific member of the little shrikethrush complex. Genetic investigations of New Guinea populations of the little shrikethrush indicate high levels of genetic divergence, suggesting it comprised more than one species.[1]
It is found on Tagula Island in New Guinea. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests.
