Pale-bellied white-eye south-east of Sulawesi in Indonesia. The Wangi Wangi white-eye has a number of differences from the pale-bellied white-eye including larger size, a black body, a long yellow beak, a gray breast and pale feet. Like most white-eyes it has a white ring around the eye and green upperparts. Pale-bellied white-eye The pale-bellied white-eye ("Zosterops consobrinorum") is a species of bird in the Zosteropidae family. It is endemic to Sulawesi in Indonesia. Its natural habitat is subtropical or tropical moist lowland forests. The species has a limited distribution and also appears to be sensitive to human disturbance. Although not yet recognized
Evolution of human colour vision allow them to see a wider range of the electromagnetic spectrum. Secondly, new random connections would create wavelength opponency and the new wavelength opponent neurons would be much more sensitive than the non-wavelength opponent neurons.This is the result of some wavelength distributions favouring excitation instead of inhibition. Both excitation and inhibition would be features of a neural substrate during the formation of a second pigment. Overall, the advantage gained from increased sensitivity with wavelength opponency would open up opportunities for future exploitation by mutations and even further improvement.
