Ranongga White-eye

Similar to Ortolan and Cretzschmar's Buntings. Males are faintly-streaked with a yellow-green head. Some populations have a yellow belly while others have a gray-white belly. Females and young lack bright yellow tones and are faintly streaked on the throat and breast. Belly whitish, not orange or buff like Ortolan and Cretzschmar’s Bunting. Breeds on open rocky mountain slopes with scattered bushes. During migration found in a varity of open habitats. Flight call is similar to that of Cretzschmar's Bunting, a sharp "Tzip."

Not the only blue nuthatch, but the bluest nuthatch. Unmistakable, with a dark head, pale eyering, white throat and breast, and dark-lined pale blue feathers on the wings. Gives quick, sharp, nasal “tzwp” or “tzwit” notes. Clambers up and down tree trunks, often in small parties; frequent member of mixed-species foraging flocks. Favors montane and hilly forests. 

Endemic to New Zealand. Uniformly slate-blue duck with chestnut spotting on the breast. Bill is pale pink with a black tip. Males larger than females, with more breast spotting and more prominent green iridescence on the head, neck, and back. Found on clear, fast-flowing mountain streams. The Maori name, whio, is derived from the male’s high-pitched, wheezy whistle. Female’s call is a low rasping growl, often in response to disturbance. Readily distinguished from Pacific Black Duck or Mallard by uniform coloration and, if on the water, prominent tail tilted upward and head held erect.
