Pycroft's Petrel
Pterodroma pycrofti
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.

White-throated Spadebill
Platyrinchus mystaceus
Tiny bird of forest undergrowth, named for exceptionally broad bill (difficult to see). Very small and short-tailed. Brown above and pale below, with black pattern on cheek. Yellow crown difficult to see. Sexes alike. Gives a single squeaky call and an ascending trill. Usually seen singly or in pairs, always in the lower levels of the forest. Inconspicuous.
Ochre-breasted Antpitta
Grallaricula flavirostris
Small and fairly bright antpitta found in foothills and subtropics from Costa Rica to Bolivia. Typical antpitta shape: plump and short-tailed. Dull brown above. Messy-looking buffy face and eyering. Some geographic variation: breast color varies from buffy to whitish, and some populations show bold dark scaling on breast, while others are nearly unmarked. Sexes similar. Shy and difficult to see; stays on or near the ground in forest, often perching on small limbs a couple meters high (more so than the larger antpittas). Swings its body side to side. Song can be difficult to detect: a simple, extremely high pitched, descending whistle. Occurs from around 500–2,500 m, usually lower than other small antpittas.
Western Spindalis
Spindalis zena
Uncommon in thickets, forest edge, and gardens, where found mainly at fruiting trees and bushes. Usually in pairs or small flocks, and often quite inconspicuous. Handsome male is unmistakable, with bold head pattern, golden-yellow and dark reddish body plumage, and bold white wing pattern. Female is notably drab, grayish olive overall with a small white mark on the wing, and a ghosting of the male wing pattern.
