Peruvian Pipit

Small gadfly petrel. Gray upperparts and head, with darker “M” across wings. Underside white, with thin dark wing edge leading into a short diagonal bar cutting into the underwing. Main colonies breed on Mercury, Hen and Chickens, Poor Knights, and Ririwha Islands in New Zealand. Forages in warmer waters off the northern North Island. After breeding, migrates to the central North and Southwest Pacific. Cook’s Petrel is larger and paler but hard to differentiate at sea. Gould’s Petrel has a darker head, giving it a capped appearance, and more extensive dark on the underwing.

Medium-sized honeyeater with an olive-brown back and pale gray underparts. Size and plumage varies considerably across its range. This species tends to favor inland locations, and is found in a wide variety of habitats. Widespread across Australia, and is present in most areas apart from the eastern coast.

Small pear-shaped gamebird. Breeds in taller grassland and grain fields from western Europe east to central Asia and winters in similar habitat in Africa, southern Europe, and South Asia. Rarely seen, and most often detected by male’s emphatic whistled "wet-my-lips!" song, which can be given at night. When flushed, explodes from underfoot and flies off strongly with whirring wingbeats and short glides. Plumage cryptic and streaky brown with pale eyebrow; male has black throat stripe. Very similar to Japanese Quail, whose male has a much darker face; females, immature birds, and domestic types (kept as captive for eggs and can escape) are probably not safely separable in the field.
