Annotated Checklist of Birds of Haleakala National Park, Maui WESTERN BIRDS Volume 15, Number 3, 1984 ANNOTATED CHECKLIST OF BIRDS OF HALEAKALA NATIONAL PARK, MAUl, HAWAII SHEILA CONANT, Department of General Science, University of Hawaii, 2450 Campus Road, Honolulu, Hawaii 96822 MAILE STEMMERMANN KJARGAARD, P.O. Box 476, Volcano, Hawaii 96785 HaleakalaNational Park (Figure1), especiallyits Crater District(Figure 2), is one of the naturalareas in Hawaii mostfrequently visited by backpackers, day hikersand motorists.The KipahuluDistrict (Figure 3) of the park, a for- mally designatedWilderness Area, is not open to publicaccess because it containssensitive ecosystems with rare plantsand animals.The park is Maui's largestnature reserve, and one of the largestsuch areas in the state.It con- tainsmany examplesof endangeredor rare plants,animals and ecosystems. The avifauna of the entire park, which consistsof these two districts,is the subjectof this paper. No recentstudies have focusedintensively on the distributionand abun- dance of birds in Haleakala National Park. Dunmire (1961) listed and describedthe bird speciespresent in Haleakalaand Hawaii Volcanoesnation- al parks, but gave little detailedinformation on distributionand abundance. The unpublishedreport (Warner1967) of an expeditionto KipahuluValley (now partly includedin the Kipahulu Districtof HaleakalaNational Park) describedthe rediscoveryof two endemicspecies of Hawaiian forestbirds, but no other avifaunalsurveys of Kipahulu took place until we began the work describedhere. Since our work was completed, the U.S. Fish and WildlifeService has also completed its surveys of forestbirds on the islandof Maul (Scottet al. ms.), but theircoverage of the park wasless comprehensive than ours, and they were unable to surveyareas repeatedly or at different seasonsof the year. In 1975 the Cooperative National Parks Resources StudiesUnit (CPSU) funded researchersat the Universityof Hawaii to con- duct inventoriesof the biotain Hawaii'stwo nationalparks. The resultsof the avifaunalsurveys of the Crater and Kipahuludistricts of HaleakalaNational Parkprovided the basisfor this checklist.

During that period of time we spent184 daysin the field: 79 daysin the Crater Districtand 105 daysin the KipahuluDistrict. We have includedthe time spentby severalbiologists who assistedus in our surveys(see Acknowledgments). We also includedinfor- mationfrom the publishedliterature, as cited in the text. Nomenclaturefollows the AOU Checklist(AOU 1983), exceptas noted. Some Hawaiian namesfor speciesfollow Pyle (1983). The biogeographic status(i.e., endemic, indigenous,exotic) is given for each species,and was determined from the literature. In this paper an endemic species or subspeciesis one whose natural (i.e., deliberateor accidentalhuman influ- ence not involved)distribution is limitedto the HawaiianArchipelago or to a singleisland or group of islandsin the archipelago.An indigenousspecies is /',,.,.HALEAKALA •, '""•TIONALPARK Kaumakani Figure 3.

An exoticspecies is one that hasbeen deliberatelyor accidentallyintroduced to the HawaiianArchipelago by humanactions. Figures 2 and 3 showdetails of the two districts,including the place namesused throughout the text. We identifiedfive habitattypes in the Crater Districtby usingWhiteaker's (1983) vegetationmap for the area. Whiteakeridentified 53 plant commu- nitytypes, but we combinedthese into five habitattypes that wereadequate for describingbird distributions.Figure 4 showsthe distributionof the five vegetationtypes we will be usingin this paper. Becauseno similarmap of vegetationtypes for the KipahuluDistrict has been produced, our discussion of bird distributionin that districtis more general. For detailed discussionsof arian distributionand abundance,the reader is referredto two additionalreports. The firstof thesecontains detailed distribu- tion and abundancemaps for the bird speciesfound in the Crater District (Conantand Stemmermann1979). The secondis a briefreport on the birds of the Kipahulu District, with maps of endangeredspecies' distributions (Conantand Stemmermann1980). Thesereports may be obtainedfrom the authors. ANNOTATED CHECKLIST FamilyProcellariidae -- Shearwatersand Petrels DARK-RUMPED PETREL Pterodromaphaeopy•?ia (Hawaiian Petrel, Uau) Endangeredspecies; Hawaiian subspecies,P. p. sandwichensis,endemic. Recent studiesby Simons(1983) indicatethat nestingburrows within the park are found on the westrim from Red Hill to above Holua Cabin, on the easternpart of the southrim, and near the summitof Hanakauhi. AlthoughSimons also found nestingcolonies out- sidethe park itself, most of the breedingpopulation of this endangeredbird is within the Crater District. Our observationsinclude sightingson the south rim above KapalaoaCabin, althougha one-nightsearch during the breedingseason revealed no burrows. We heard this bird at Puu Mamane about one hour after sunset in June 1976 and June 1977. G. Teves (pets. comm.) heard this speciesat Paliku2-3 hoursafter sunsetin June, July and August1977. Simonsestimated the total breedingpopulation of this specieson East Maui to be 575 pairs. FamilyPhaethontidae -- Tropicbirds WHITE-TAILED TROPICBIRD, Phaethonlepturus (Koa e kea) Indigenous.

The Save Our Shearwaters (SOS) program was created in 1979 to address this issue and to date has recovered and released to sea more than 30 500 fledglings. Although the value of the program for animal welfare is clear, as birds cannot simply be left to die, no evaluation exists to inform post-release survival. We used satellite transmitters to track 38 fledglings released by SOS and compared their survival rates (assessed by tag transmission duration) to those of 12 chicks that fledged naturally from the moun- tains of Kaua‘i.

Threats to both species include light attraction and fallout, collisions with power lines and other structures, predation by invasive animals, and habitat degradation. Both species were assumed to be extirpated from the island of Oahu despite limited survey effort. We used survey data from Kauai (both species) and Maui (Hawaiian Petrel only) to model suitable habitat and light conditions. We then projected this model onto Oahu to identify potential survey sites. From April to September of 2016–2017, we deployed automated acoustic recording units at 13 potentially suitable sites across Oahu. We detected Newell’s Shearwaters at 2 sites; one on the leeward slopes of Mount Kaala in the Waianae Mountains and another at Poamoho in the Koolau Mountains.

  • Movement Patterns of Hawaiian Petrels and Newell's Sheatwaters
    Movement Patterns ofHawaiian Petrels and Newell's Sheatwaters on the Island ofHawai'i1 Robert H. Day, 2 Brian A. Cooper, 3 and Richard]. Blaha3 Abstract: We studied movements and distribution and abundance of endan­ gered Hawaiian Petrels ('Ua'u [Pterodroma sandwichensis Ridgway]) and threat­ ened Newell's Shearwaters ('A'o [Puffinus auricularis newelli Henshaw]) on the island of Hawai'i in May-June 2001 and 2002. We recorded radar targets of either species at 14 of the 18 sites but recorded no birds visually at any site. Movement rates of petrels and shearwaters were very low (0-3.2 targets per hour) over all except one of the sites (Waipi'o Valley: 25.8 targets per hour). We saw radar targets moving from shortly after sunset throughout the rest of the sampling, suggesting that both petrels and shearwaters were present. Highest movement rates occurred 1-2 hr after sunset, when primarily Newell's Shear­ waters are flying. Timing of evening movements suggests that Hawaiian Petrels fly over the northern and southern parts of the island and may dominate on Mauna Loa and Mauna Kea. In contrast, timing suggests that Newell's Shear­ waters fly over essentially the entire island (except in the southwestern part, where no birds appear to occur), dominate numerically in the Kohala Moun­ tains, and occur in low numbers on Mauna Loa, in the Puna District, and on the northern slopes of Mauna Kea. Evening flight directions were predominantly inland at all sites except four. The limited radar data suggest that a substantial population change did not occur in the Puna District from 1995 to 2001-2002.

  • Status and Occurrence of Hawaiian Petrel (Pterodroma Sandwichensis) in British Columbia. by Rick Toochin. Submitted: April 15, 2017
    Status and Occurrence of Hawaiian Petrel (Pterodroma sandwichensis) in British Columbia. By Rick Toochin. Submitted: April 15, 2017. Introduction and Distribution The Hawaiian Petrel (Pterodroma sandwichensis) is a seabird that is an Endangered Species that breeds on Hawaiian Islands (Simons and Hodges 1998). This species is in the deep ocean Pterodroma family of seabirds also called “gadfly” petrels (Onley and Scofield 2007). Breeding extends from March to October. Current breeding population estimates from known nest sites on the islands of Maui and Hawai‘i range from 450 to 650 pairs (Simons and Hodges 1998). Total population estimates, based on observations of birds at sea and birds flying inland on Kaua‘i Island, range from several thousand to 34,000 birds (Coulter 1984). New research employing microwave telemetry shows that the birds travel as far as Alaska and Japan during two-week-long feeding trips. Away from breeding grounds, occurs primarily in equatorial waters of the eastern tropical Pacific, generally between 20°N and 10°S (Pitman 1986). This species is usually encountered as solitary birds that are not actively feeding (Simons and Hodges 1998). Feeding most often noted when birds join mixed-species flocks feeding on live prey (Pitman and Ballance 1997). In spring, found to 25°N (King 1970); in July and August to 50°N in southern Gulf of Alaska (Bourne 1965, Bourne and Dixon 1975). Formerly lumped with Galapagos Petrel (Pterodroma phaeopygia) and was called Dark-rumped Petrel, until it was split by the A.O.U. into 2 species in 2002 (A.O.U. 2002). This decision follows research that showed the two taxa differed in vocalizations, morphology, and breeding seasons (Tomkins and Milne 1991), and biochemically (Nunn et al.

These images were selected to illustrated variation in the appearance of presumed Hawaiian Petrels in Hawaiian waters. All of these photographs show features associated with Hawaiian Petrel as opposed to Galapagos Petrel (Force et al. 2007): the birds have a capped appearance, with a notch of white behind the eye, rather than a strongly cowled appearance typical of Galapagos Petrel; narrow dark trailing edges of the underwing (typically broader in Galapagos Petrel); white flanks free of dark mottling, a mark shown by some Hawaiian Petrels but averaging heavier and more prevalent in Gala - pagos Petrels (see also Figures 2 and 4); and delicate structure and small bill typical of Hawaiian Petrel rather than the rangier, bulkier, larger-billed appearance associated with Galapagos Petrel (Force et al. 2007). These photographs (compare also Figure 2) demonstrate that the angle of the photograph relative to that of the bird and type of lighting can affect the appearance of Pterodroma petrels sub - stantially.

  • ATST 2012 Hawaiian Petrel Monitoring Report
    ATST 2012 Hawaiian Petrel Monitoring Report ATST 2012 Hawaiian Petrel Monitoring Report H. Chen, C. Ganter, J. Panglao Advanced Technology Solar Telescope December 2012 ABSTRACT The Advanced Technology Solar Telescope (ATST) Resource Management Team monitored burrows of the Hawaiian Petrel (Pterodroma sandwichensis) on the summit area of Haleakalā from February through November of 2012. All data presented in this report was collected prior to the start of construction (November 30, 2012) of the ATST. This year a total of 306 Hawaiian Petrel burrows were documented and monitored. Of these burrows, 163 were active and 16 were successful at producing a fledged chick at the end of the nesting season. Statistical analysis showed that active burrow density in the ATST Conservation Area was significantly higher than in the Control site when compared to the expected values (P<0.0001, χ2= 20.569, df=1). Invasive mammalian predators were the primary cause (n=6, 85.71%) of mortality. The Hawaiian Petrel chicks fledged between the first week of October and the first week of November, with the most fledged chicks occurring during the second and third week of October. For burrows monitored by video surveillance, the earliest fledging date recorded on camera was October 12, 2012 and the latest date was October 19, 2012. The breeding success rate in the Conservation Area was 10.39%, and 0% in the Control site, yielding an overall reproductive success rate of 9.82%. A chi-square test showed there were significantly more active burrows from 2011 that remained active in 2012 when compared to expected values (P<0.0001, χ2= 20.609, df=1).

Haleakala began as part ofHawaii National Park on 1 August 1916. It was later renamed Haleakala National Park on 13 September 1960 and became a separate entity in 1961. The United Nations recognized Haleakala as an International Biosphere Reserve in 1980. Haleakala is now one oftwo national parks in the Hawaiian Islands. The park encompasses outstanding volcanic terrain and subtropical rainforests. The centerpiece ofthe national park is the volcanic mountain Haleakala. Its name meaning "house ofthe sun," rises to an altitude of 10,023 feet above sea level and some 30,000 feet from its base on the ocean floor. Haleakala is a shield volcano formed by successive eruptions oflava probably emerging from the sea about 1 million years ago. Although often referred to as a crater, it is actually a valley formed by thousands of years of erosion. Two gaps, or valleys on the side ofthe mountain created by erosive action, eventually connected forming a great crater.
