Heard Island Shag

Small, spunky wren with boldly patterned plumage. Look for dark cap, bright white eyebrow, and black-and-white stripes on back. Compared with similar Sedge Wren, Marsh is overall darker and more contrasty; especially note the solid brown shoulder patch and unstreaked crown. Habitat is also a good clue for identifying this wren: rarely strays far from water, especially extensive cattail marshes and rushes. Migrants are occasionally seen in wet weedy fields. Often difficult to see well as it skulks through reeds, but often perches conspicuously when singing. Variable song usually a gurgling trill with some introductory notes.

Medium-large black-and-white woodpecker. Marginally smaller than Great Spotted Woodpecker, but rounded head and shortish beak exaggerate this size difference. Both sexes are similar, with a red crown (brighter in the male) and an incomplete cheek bar. It has a rattle call: "kíg-gag-gag-gag-gag" and gives a nasal long-drawn series of “gwaaag” calls. Rarely drums. Closely tied to old deciduous forests, often in areas with an abundance of oak or beech.

Atypical kestrel that is marked more like a small hawk, with a gray back and a barred belly. Uncommon to rare Madagascar endemic that is found patchily across the island in and adjacent to forest. Absent from most of the east and center of the island. Sits motionless on prominent perches for long periods. Flights are short, low, and infrequent. Call is a quick rolling “tr-r-r-r.” Larger and chunkier than Madagascar Kestrel, gray rather than rufous, and with broad bars on the belly. Separated from sparrowhawks by big-headed kestrel shape and upright posture.
