Procellariidae Wedge-T ailed Shearwater (Puffinus pacificus) Approximately 100 “wedgies” were seen on our pelagic trip off the south side of Kaua’i. Nest burrows were seen at close range at Kilauea NWR on 3/16 but no birds were detected (they feed out at sea during the daytime.) Sooty Shearwater (Puffinus griseus) Several were seen on our Kaua’i pelagic on 3/17. Others were seen by a few of our group from the end of the Chain of Craters Road on the Big Island on 3/21. Christmas Shearwater (Puffinus nativitatis) At least one bird was seen well in flight and on the water during our pelagic. First spotted by David Kuhn. Identification: a mediumsized, dark-brown shearwater with a short, wedge-shaped tail and a shiny, black bill. Adult males and females are entirely dark brown, although underparts are lighter than upperparts. Flight is characterized by fast, stiff wing beats, followed by long glides. Abundance: In Hawai‘i, breeding colonies estimated at less than 3,000 pairs. Worldwide population unknown but likely less than 10,000 breeding pairs.

Red Junglefowl (Gallus gallus) [The Red Junglefowl is Hawai’i's first introduced species. Colonizing Polynesians brought it to Hawai’i over 700 years ago.] We did not count the hybrids seen all over the Kaua’i lowlands’ however, the ones seen at Kōke’e State Park are considered to be “purebreds,” (especially the ones with darker legs and fewer white feathers). Some noncountable birds were also seen on the Big Island lowlands. Kalij Pheasant (Lophura leucomelanos) [Introduced from Southeast Asia in 1962.] A cooperative bird was seen along the road in the Hawai‘i V olcanoes National Park on the Big Island on 3/16. A second bird was seen by Phil on 3/17 near our lodge at V olcano on the next morning.

Rallidae Common Moorhen ['Alae 'Ula] (Gallinula chloropus sandvicensis) [subspecies also called “Hawaiian Gallinule”] [Endemic/Endangered Subspecies] Only one bird was seen on Kauai at Hanalei NWR from the road above and at a distance. Identification: The frontal shield appears slightly larger and extends higher up the forehead than on the mainland form; front of tarsi reddish.Abundance: Island-wide population, based on semiannual waterbird counts suggests that the population is increasing, but count numbers are variable. Between 1993 and 2003, the average annual number counted has been just under 300 individuals. Hawaiian Coot (Fulica alai) [Endemic/Endangered] Observed on O’ahu at Kuhuku Golf Course on 3/15; at Hanalei NWR on Kaua’i on 3/17; and on the Big Island at the Big Island County Club and at the Kona Sewage Ponds on 3/23. [Phil and Barbara saw them again on the Big Island on 3/25, after the tour at the same Country Club and at the Aimakapa Pond.] Identification: V ery similar to the American Coot (F . americana), but is slightly smaller in size and has a larger, more bulbous white frontal shield. Abundance: The population is stable and is estimated at between 2,000 and 4,000 individuals. T axonomy: Split from American Coot by the AOU in 1993.

On the Big Island, many more were seen at the Kona Sewage Ponds on 3/23 and on 3/24 when a flock flew over our hotel. [Phil and Barbara also saw more at the Aimakapa Pond on the Big Island on 3/25 after the tour ended.] Identification: The Hawaiian subspecies differs from the North American subspecies by having more black on its face and neck, and longer bill, tarsus, and tail. Abundance: Between 1993 and 2003, the average annual number counted has been approximately 1,300 individuals; in 2001 an average of 2,680 individuals was recorded. Taxonomy: The Hawaiian Stilt is currently regarded as a subspecies of the Blacknecked Stilt but evidence suggests that it may be better considered a full species. Stay tuned …

Also seen in the lagoon at our hotel on the Big Island on 3/23 and 3/24 [and here on 3/25 by Phil and Barbara after the tour ended.] Sanderling (Calidris alba) A few were seen at the Salt Pond Park on Kaua’i on 3/16, and at the Kona Sewage Ponds on the Big Island on 3/23. Also seen in the lagoon at our hotel on the Big Island on 3/23 and 3/24. [Phil and Barbara had several on the beach near the Aimakapa Pond on the Big Island 3/25 after the tour ended.]
Sternidae Gray-Backed T ern (Sterna lunata) At least one was seen very well by all on our Kaua’i pelagic on 3/17. Identification: Similar to Sooty Terns, except back, wings, and tail feathers gray. Head and eyestripe are black. White forehead extends further back behind the eye than the sooty tern. Abundance: Worldwide breeding-population size is unknown, but possibly on the order of 70,000 breeding pairs. In Hawai‘i, population is estimated at 44,000 breeding pairs in Nihoa and other Northwest Islands. Sooty Tern (Sterna fuscata) Distant views of the huge colony on Manana Island Seabird Sanctuary off O’ahu on 3/15. Also, close views from the boat on our Kaua’i pelagic on 3/17.

Black Noddy (Anous minutus) Several birds were seen from the boat on our 3/17 Kaua’i pelagic. On 3/21, we saw many birds around the cliffs and over the ocean at the end of the Chain of Craters Road in Hawai‘i V olcanoes National Park. [Phil and Barbara saw more over the water at South Point on 3/25 after the tour ended.] Identification: Birds in Northwestern Hawaiian Islands differ from those in main, southeastern islands in plumage color, leg and foot color, and size. Treated as “dark phase” (northwestern form) and “light phase” (southeastern form) color morphs of subspecies A. m. melanogenys by some authors. Northwestern birds slightly darker overall, with dark gray tail; paler gray tail of southeastern birds contrasts conspicuously with dark back. Legs and feet of southeastern adults usually bright orange (dusky orange to orange-yellow), unlike the mostly darker legs and feet of all other subspecies. Northwestern birds significantly larger than southeastern birds in wing, culmen, and middle toe.Abundance: In Hawai‘i, population estimated at 12,000 breeding pairs with the largest populations occurring on Midway Atoll and Nihoa. T axonomy: Seven subspecies recognized. Two distinct forms breed in Hawaiian Is.: Unpublished data indicate that northwestern form closely resemblesA. m. marcusi of nearby nw. Pacific in plumage color, leg and foot color, and size. Therefore, northwestern form is probably referable to subspecies A. m. marcusi, with subspecies name A. m. melanogenys thus restricted to southeastern form.

Page 17 of 34
Alaudidae Sky Lark (Alauda arvensis) [Introduced from England in 1865 and via New Zealand in 1870] Fairly common on the Big Island along Saddle Road on 3/23 and 3/24. [Phil and Barbara also found them on the Big Island around South Point on 3/24 and north near Wiamea on 3/25, after the tour ended.] Population: Population of at least ~10,000 is estimated on the Big Island. T axonomy: V arious authorities recognize 7–16 subspecies, worldwide. Wide range of individual variation makes subspecific diagnosis difficult without comparative series. Characters that are used to differentiate subspecies include wing length, plumage coloration, thickness and taper of bill, length of hind claw, crest profile, length of secondaries and tertials, and comparative lengths of primaries. Two subspecies known for North America; the nominate European subspeciesA. a. arvensis, probably comprises the bulk of the Hawaiian population [PCD]. A. a. japonica reportedly was introduced once in Hawai’i in 1934. Specimens identified as thepekinensis race from extreme e. Asia have been collected from the Pribilof Is. and Hawaiian Is. Red-Vented Bulbul (Pycnonotus cafer) [First appeared on O’hau in the mid-1950s as an unauthorized cage release.] Common throughout O’ahu on 3/15.

Monarchidae General ‘Elepaio Identification: BNA Online: “Geographic V ariation: Considerable plumage variation among islands, with more subtle differences within the Big Island. On the Big Island, dark brown above; white below, with variable amount of brown streaking; rufous or white in eyebrow and auriculars. Males have mostly black throat, females mostly white throat. At high elevations on w. Mauna Kea, more white on head, darker gray brown above, less streaked below. On O‘ahu I., brown above; white below, with light brown streaks on upper breast; lores white; auriculars dark. Males usually have more black on throat than females, but some overlap. Plumage dullest on Kaua‘i: Sexes alike; grayish above; white below, with orange brown wash on breast. Birds larger in wing and mass on Hawai‘i I. than on O‘ahu and Kaua‘i Is., but birds on O‘ahu have larger bill.” General ‘Elepaio T axonomy: BNA Online: “Taxonomy of ‘Elepaio has changed repeatedly, with considerable disagreement and confusion about number of taxa and their distribution caused by variation in plumage among and within islands, distinct subadult plumages in both sexes that differ among islands, and differences among islands in degree of sexual dimorphism. Taxa on each island were formerly
Page 19 of 34
considered separate species, and as many as 5 species have been recognized, sometimes without regard to island of origin. Several forms were incorrectly described from immature birds and are not valid. All forms were combined into 1 species by Bryan and Greenway, with former species regarded as subspecies. Systematic investigation of genetic, morphological, and vocal variation has begun and will help assess whether taxa on each island should be regarded as distinct species, as well as extent of variation within Hawai‘i Island populations.” V anderwerf (2007): “The 'Elepaio (Chasiempis sandwichensis) is a monarch flycatcher (Monarchidae) endemic to the Hawaiian Islands. 'Elepaio occur on the islands of Kaua'i, O'ahu, and Hawai'i, but are absent on the four islands (Maui, Moloka'i, Lana'i, and Kaho'olawe) in the center of the Hawaiian Archipelago. 'Elepaio have been classified into three or more taxa based primarily on plumage differences, each found on a single island. Each island taxon was originally described as a separate species:C. sandwichensis on Hawai'i; C. ibidis [gayi] on O'ahu; and C. sclateri on Kaua'i. These taxa were later reclassified as subspecies by Bryan and Greenway without any explanation or justification, and this taxonomy has been followed since. Some authorities continue to treat them as species, and the American Ornithologists' Union is considering a taxonomic revision of 'Elepaio in which the forms on different islands would again be separated as species. Two additional subspecies,C. s. ridgwayi and C. s. bryani, are recognized on Hawai'i by some authorities, based on variation in plumage color on the head, back, and breast.” So, there are three options regarding how to handle this endemic complex. Option 1 (the baseline) follows the Clements Checklist which indicates that there is only one‘Elepaio species that includes five subspecies. Option 2 yields three ‘Elepaio species, one each for the islands of O’hau, Kaua’i, and Hawai’i, with the later consisting of three subspecies (Hawai’i, V olcano, and Mauna Kea). With Option 3 there are five separate species of ‘Elepaio, with the Big Island group consisting of three separate species. Stay tuned … O’ahu ‘Elepaio (Chasiempis sandwichensis gayi) [Endemic/Under consideration for Endangered status] We saw this form on O’ahu on 3/15 at the along the Kuli’ou’ou V alley Trail streambed. Identification: Crown and back dark brown; underparts white, very lightly streaked with brown on upper breast. Lores white, auricular mostly black, eyebrow and forehead rufous, forming contrasting pattern. Male usually more black on throat than female, especially chin, but sexes not always distinguishable. Kauai ‘Elepaio (Chasiempis sandwichensis sclateri) [Endemic] We saw a number of this form on Kauai’i in the Alaka'i Wilderness on 3/18 and 3/19. Identification: Crown and back dark grayish brown; underparts white with orange brown wash on upper breast. Sexes alike.

Hawai’i ‘Elepaio Group (Chasiempis sandwichensis) Identification: BNA Online: “Hawai‘i Island. (C. s. sandwichensis, C. s. ridgwayi, and C. s. bryani). Dark brown on crown and back, with contrasting eyebrow and forehead of rufous or white. Underparts white, with light to heavy brown streaks on breast. Throat usually mostly black in males, white in females.C. s. bryani differs in having mostly white eyebrow and auricular, grayer crown and back, and more lightly streaked breast.C. s. ridgwayi is generally darker and more heavily streaked below.C. s. sandwichensis often has more white in the eyebrow than C. s. ridgwayi.” T axonomy: BNA Online: “C. s. sandwichensis occurs in dry, leeward forests of w. and s. Hawai‘i I., from w. Ka‘ü on southern slope of Mauna Loa north through Kona on western slopes of Mauna Loa and Hualälai. C. s. ridgwayi occupies wet forests of e. Hawai‘i I. from e. Ka‘ü, V olcano, and Puna north across Hämäkua on eastern slope of Mauna Kea, to Kohala at northern tip of island. C. s. bryani is limited to small area of high-elevation forest primarily on western side of Mauna Kea. Intergradation occurs on Hawai‘i I. between ridgwayi and sandwichensis in Ka‘ü on southeastern slope of Mauna Loa, and between ridgwayi and bryani at higher elevations on northeastern slope of Mauna Kea. Isolated populations in central Hawai‘i I. at Pöhakuloa and in Saddle Road area between Mauna Kea and Mauna Loa may be mixture of all 3 subspecies.” V olcano ‘Elepaio (Chasiempis sandwichensis ridgwayi) [Endemic] We encountered this species on the Big Island in Hakalau NWR on 3/22. Hawai’i ‘Elepaio (Chasiempis sandwichensis sandwichensis) [Endemic] We found this form on the Big Island on 3/21 at Manuka State Park.

Timaliidae Hwamei [Melodious Laughing-Thrush] (Garrulax canorus) [First identified in the late 1960s but may have been introduced as early as 1919.] We saw this species on Kauai’i in the Alaka'i Wilderness on 3/18 and 3/19. Red-Billed Leiothrix (Leiothrix lutea) [Introduced from China in 1918.] We saw and heard this species along the Kuli’ou’ou V alley Trail streambed on O’ahu on 3/15. Several birds were also heard, but not seen, on the Big Island at Hakalau NWR and also at the Big Island County Club on 3/22 and 3/23.

Distribution: Hawai‘i ‘Amakihi occur between 300 and 2,900 meters (1,000 – 9,500 feet) on the islands of Hawai‘i, Maui and Moloka‘i. Abundance: The Hawaiian Forest Bird Survey estimated the Hawai‘i ‘Amakihi population at ~870,000 individuals on the island of Hawai‘i. O’ahu ‘Amakihi (Hemignathus chloris) [Endemic] We saw this species on 3/15 on O’ahu at the Wa'ahila Ridge State Recreation Area and along the Kuli’ou’ou V alley Trail streambed. Identification: The O‘ahu ‘Amakihi is brighter and smaller than the Kaua‘i ‘Amakihi.Abundance: A 1991 survey conducted by the State of Hawai‘i Division of Forestry and Wildlife estimated the O‘ahu ‘Amakihi population at between 20,000 and 60,000 individuals. Kaua’i ‘Amakihi (Hemignathus kauaiensis) [Endemic] We saw a number of this species on Kauai’i in the Alaka'i Wilderness on 3/18 and 3/19. Identification: Kaua‘i ‘Amakihi are larger than `Amakihi on other islands with much larger bills in both the male and females.Abundance: A survey in the late 1980’s estimated a population of 15,000 – 20,000 individuals.

‘Anianiau (Hemignathus parvus) [Endemic] We saw a number of this species on Kauai’i in the Alaka'i Wilderness on 3/18 and 3/19. Abundance: The Kaua‘i Forest Bird Survey (2000) estimated the population within the Alaka‘i and Kōke‘e region at close to 35,000 individuals, and reported a significant population increase between 1981 and 2000. The population appears stable in its current range. ‘Akiapola‘au (Hemignathus munroi) [Endemic/Endangered] The rarest species on the Big Island. We found several birds, including a very cooperative individual, in Hakalau NWR on 3/22. Abundance: The Hawai‘i Forest Bird Survey estimated ~1500 birds.
Hawai‘i Creeper (Oreomystis mana) [Endemic/Endangered] Several seen rather well at Hakalau NWR on 3/22. Abundance: Population estimates based on Hawai‘i Forest Bird Survey conducted in the early 1980s indicated a total population of about 12,400 birds.

‘Akeke‘e (Loxops caeruleirostris) [Endemic/Endangered] In the Alaka'i Wilderness on Kauai’i, one bird was heard on 3/18; however, another was seen by our group on 3/19. Abundance: The Hawaiian Forest Bird Survey (1981) estimated a population of ~1674 in the central Alaka‘i region. The population appears to have remained stable during the last 35 years despite declines of other Kaua‘i forest birds and the impact of two hurricanes. ‘Akepa (Loxops coccineus coccineus) [Endemic/Endangered] Several seen rather well at Hakalau NWR on 3/22. Abundance: The Hawai‘i Forest Bird Survey estimated the ‘Akepa population to include ~14,000 individuals in 1980.

‘I‘iwi (V estiaria coccinea) [Endemic] In the Alaka'i Wilderness on Kaua’i, this species was only seen by a few on 3/18 and it was heard on 3/19. However, on the Big Island, we saw many on 3/22 at Hakalau NWR. Barbara saw a juvenile bird on 3/23 at the Mamane-Naio Forest. Abundance: The following island population estimates are based on Hawaiian Forest Bird Surveys (1976-1981): ~340,000 individuals on island of Hawai‘i (88% in Hāmākua), ~19,000 individuals on east Maui, ~180 on west Maui, ~80 individuals on Moloka‘i, and ~5,400 in the Alaka‘i Swamp on Kaua‘i. Recent surveys (1996) suggests O‘ahu supports less than 50 birds. In 1988, two birds were detected on Moloka‘i. On Kaua‘i, populations declined after the 1992 hurricane, but changed little between 1994 and 2000. The overall population may be declining, but the species’ wide-ranging foraging complicates population estimates and the determination of long-term trends.
‘Apapane (Himatione sanguinea) [Endemic] Seen daily in the highlands of Kaui’i and the Big Island from 3/18 through 3/22. Plentiful at our lodge at V olcano on 3/20 and 3/21. A few saw one on 3/23 at the Mamane-Naio Forest. Abundance: The following island population estimates are based on Hawaiian Forest Bird Surveys (1976-1981): ~1,080,000 individuals on island of Hawai‘i, ~110,000 individuals on Maui (86% on Haleakalā), ~39,000 individuals on Moloka‘i, ~540 individuals on Lāna‘i, and ~30,000 individuals on Kaua‘i. On Kaua‘i, populations declined after the 1992 hurricane but have significantly increased since. The 2000 Kaua‘i Forest Bird Survey estimated the population at ~64,972 individuals.
