Breeding.<\/em><\/strong>\u00a0 Breeds from November to May on Isla Alejandro Selkirk (a.k.a. Masafuera), the more distant of the two main Juan Fern\u00e1ndez Islands.\u00a0 Nests alongside the Juan Fern\u00e1ndez Petrel<\/strong><\/a> in burrows on slopes in fern-forest, fern-scrub and adjacent meadows and ridges at 850-1,100 m elevations of Cerro de los Inocentes.<\/p>

The global population is fairly large, estimated in 1987 at 655,000 individuals, but is thought to be in a steady long-term decline, primarily due to predation by invasive mammals: cats, rats, mice, and dogs.<\/p>

Nonbreeding.<\/em><\/strong>\u00a0 Most of the population is believed to spend June through September far offshore in the northwestern Pacific, in the Oyashio-Kuroshio Extension Current southeast of Japan.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Their main wintering area is remote enough that they are rarely detected during this season even around Japan\u2019s distant oceanic islands.\u00a0 Typhoons have occasionally transported significant numbers to the coast of Honshu.<\/p>

Movements.<\/em><\/strong>\u00a0 The general pattern of migration around the Pacific appears to be counterclockwise.\u00a0 In April and May, they depart roughly west-northwest from Chilean waters through Polynesia, passing mostly south of Hawaii.\u00a0 When returning in September and October, they pass through Hawaiian waters, then turn south.<\/p>

Wanderers have been recorded several times in the northeastern Pacific, in the waters off of Oregon and California, mainly in October and November, and on the opposite side of the ocean in the southwestern Pacific, in the waters of New Zealand, eastern Australia, and Tasmania.\u00a0 There are enough records to suggest that low numbers may occur regularly in both regions.<\/p>

One extraordinary vagrant was found dead on the Gulf of Mexico shore of Nueces County, Texas (September 15, 1995).<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Identification<\/strong><\/span><\/p>

A small, thin gadfly petrel with strongly patterned gray-and-black upperparts and white underparts.<\/p>

The upperparts are mostly pale to medium-gray with a pronounced blackish \u201cM\u201d pattern: dark bars the full length of the wing connected by a dark bar on the lower back, accentuated by paler trailing edges on the secondaries.<\/p>

The rump is pale-gray, and the tail is mostly blackish\u2014which distinguishes it from its most similar relatives.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Cf. Pycroft\u2019s Petrel.<\/em><\/strong>\u00a0 Pycroft\u2019s and Stejneger\u2019s Petrels were traditionally considered conspecific and are extremely similar.\u00a0 They are not known to overlap regularly, but they probably do: Stejneger\u2019s has been recorded on multiple occasions in the southwestern Pacific, and Pycroft\u2019s nonbreeding range is essentially unknown, but likely included some portions of the central and northwestern Pacific where Stejneger\u2019s occurs.\u00a0 The most consistent difference between them is tail color: Stejneger\u2019s has a distinctly blackish tail that contrasts with its paler-gray rump, whereas Pycroft\u2019s usually shows only a slightly darker tail, with little if any contrast.\u00a0 At the other end, Stejneger\u2019s has a much more extensively white forehead\u2014this seems to be diagnostic, but is difficult to see clearly under most field conditions.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Cf. Cook\u2019s Petrel<\/a>.<\/em><\/strong>\u00a0 Cook\u2019s and Stejneger\u2019s Petrels overlap widely across most of the Pacific Ocean and are easily mistaken for one another.\u00a0 Stejneger\u2019s is slightly smaller in all dimensions, but this would rarely be useful under field conditions.\u00a0 The more helpful differences between them are plumage features: especially the color and pattern of the upperparts.\u00a0 Stejneger\u2019s is darker overall and has a strongly contrasting pattern: a bold, blackish \u201cM\u201d across the wings and back; a blackish tail (both darker and more extensive than on Cook\u2019s).\u00a0 The coloration and pattern of the head and neck also differ.\u00a0 In this area Cook\u2019s is a paler shade of gray overall, which accentuates the dark shadows around its eyes, and Cook\u2019s usually shows a distinct white brow.\u00a0 Stejneger\u2019s usually shows a dark cap and cowl with an extensively white forehead that may reach the eye, but not a pale brow.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Cf. De Filippi\u2019s Petrel.<\/em><\/strong>\u00a0 Stejneger\u2019s and De Filippi\u2019s Petrels occur together in the Humboldt Current waters west of South America and elsewhere in the southeastern Pacific.\u00a0 They have approximately the same overall appearance, but differ in a few details.\u00a0 De Filippi\u2019s is slightly larger and heavier and has a thicker bill.\u00a0 De Filippi\u2019s has slightly paler upperparts, most noticeable at the head and tail.\u00a0 Perhaps most noticeable in the field, De Filippi\u2019s rump and tail are both pale to medium-gray, whereas Stejneger\u2019s has a blackish tail that contrasts with its paler rump.\u00a0 On the head, De Filippi\u2019s has a pale-gray crown and cowl, which on Stejneger\u2019s are medium or dark-gray.\u00a0 Finally, De Filippi\u2019s has a pronounced white browline, which isolates and accentuates the blackish shadow around its eye.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Cf. Gould\u2019s Petrel.<\/em><\/strong>\u00a0 Gould\u2019s and Stejneger\u2019s Petrels are similar species that overlap to some extent across most of the tropical Pacific.\u00a0 Both have dark-gray cowls, which distinguish them from most related species, but Gould\u2019s has a darker cowl that typically extend farther down the neck\u2014and on some individuals may form a complete collar.\u00a0 Gould\u2019s also has generally darker-gray upperparts that show less contrast than Stejneger\u2019s, so the M-pattern on Gould\u2019s is less pronounced and its rump and tail do not contrast strongly, as on Stejneger\u2019s.\u00a0 Finally, on the underside of its wings, Gould\u2019s has wider black carpal bars.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
