Stejneger's Petrel
Pterodroma longirostris
Medium-sized, elegant seabird of the deep Pacific Ocean, rare in Japanese waters. Grayish above, white below, with dark “M” pattern in upperparts. White forehead extensive; dark gray crown stands out against lighter gray back and often terminated by a sharp white “notch” of plumage. Underwing mostly white, with only small black marks at the “wrists,” unlike many other gadfly petrels, and tip of tail extensively black, unlike rather similar Cook’s and Masatierra Petrels.

Other Birds
White-browed Antbird
Myrmoborus leucophrys
Small, short-tailed antbird with a bold eyebrow. Male is slaty gray with gleaming white eyebrow. Female is brown above and white below with a black face and an orange eyebrow. Found in young forests and forest edges, skulking in dense undergrowth alone or in pairs. Listen for a long series of harsh, descending whistles.
Helmeted Manakin
Chiroxiphia galeata
Males are striking with a mostly glossy black body, but with a red forehead, crest, and back. Females are uniformly olive-green and also crested. Locally common in gallery forests embedded in savannas where it often accompanies mixed-species flocks. The song is a trilling series of alternately soft and loud whistles.
Pitcairn Reed Warbler
Acrocephalus vaughani
A large cold-toned warbler with grayish-brown upperparts, yellowish-buff underparts, and variably white wings and tail. Irregular whitening of wings and tail give it a messy appearance. Found primarily in patches of tall forest, avoiding open areas. Voice is a harsh, scolding “chak, chak.” Does not sing.
