Hartlaub's Duck

Medium-sized songbird of woodlands, neighborhoods, and parks. Male grayish brown with black head and wings, faintly orange flanks, and a dark-tipped yellow bill. Female similar but lacks the black head, has much paler orange on the flanks, and is an overall brownish tone. Male similar to Japanese Grosbeak, which has less black on the head, no orange on the flanks, and lacks the dark tip to the bill of most adult male Yellow-billed Grosbeaks. Often detected as it gives a hard "jik!" while flying overhead.

Large black-and-white waterbird with bulbous lump on the top of its head and striking orange legs and feet. Often seen in very large, noisy flocks. Typically found in and around wetlands, pastures, and orchards across northern Australia. Also perches in trees and on branches. Soft honking calls given frequently, including in flight.

A very small nondescript sunbird with a short orange-based bill that curves uniformly along its length; easily mistaken for females of other sunbirds. The only features on the olive upperparts are indistinct paler eyebrows and lines running under the eyes, and yellow edging to the wings. Although often hidden, the male has yellow or whitish (not red) tufts at the shoulders. Singles are local and inconspicuous at the edges of lowland and riverine forest, sometimes entering secondary growth; it joins mixed-flocks and is frequently attracted to epiphytes in mossy clumps. Calls a high-pitched “tseeep” and trills. Little Green and Fraser’s sunbirds are similar to Bates’s but brighter, with straighter bills and more distinct yellowish eye-rings; Ursula’s Sunbird has a long decurved bill and grayish face and underparts.
