Black-streaked Scimitar-Babbler

A small, inconspicuous, and easily overlooked sunbird of mountain forests. At a distance, appears fairly uniform in color, but in good light the greenish back contrasts with the gray face, olive throat, pale belly, and reddish tufts on the sides of the body that are sometimes concealed by the wings. Bill is not overly long, but is distinctly curved. Within its range, most likely to be confused with Little Green Sunbird, but Ursula’s Sunbird has a plain face and more decurved, all black bill. Song varies, but always consists of sharp, high-pitched notes that are sometimes delivered as a jumble and sometimes as a single note followed by a descending pattern of quick, high pitched notes: “tsee-TSEE-TSI-tsi-tsi.” 

Tiny and strikingly-plumaged flycatcher with a long tail and distinct face pattern. Has a gray crown, a broad white eyebrow with a vertical black crescent running behind the eyes. The body is olive-yellow above and bright yellow below. An uncommon and threatened inhabitant of the middle levels of montane forests and forest edges including Araucaria forests. The song is a high-pitched trill.

A small bird, olive-green above and buffy-peach below. Has a black edge to the wing, a thin dark stripe at the base of the bill, a bold white eye-ring, and a dark thin bill. Pale eyebrow extends above and in front of the eye. Birds on Guam have a much grayer head and are more golden below. Occurs in most habitats. Voice consists mostly of high-pitched chirping.
