Pacific Reef-Heron Egretta sacra hypothetical, unsubstantiated Pacific Reef-Herons range from India E to New Zealand, Fiji, Samoa, the Tuamotu Is, and throughout Micronesia (Pratt 1987, Wiles 2005), as close to Hawaii as the Marshall Is (Clapp 1990). W. Anderson (in Cook and King 1894:228) first made mention of this species for the Hawaiian Islands, referring to it by its Tahitian name "otoo" (Medway 1981). Perhaps based on this report, Gray (1859) and Finsch and Hartlaub (1867) listed this species for the Hawaiian Islands. Dole (1869, 1879) reported a heron “common all over Hawaii” as being Ardea sacra, mistakenly applying this name to Black-crowned Night-Heron (Wilson & Evans 1890-1899, W.A. Bryan 1901, Henshaw 1902). Finsch (1880) followed Dole in reporting herons with "manners very much of our Nyctocorax" as "apparently Ardea sacra". Dole's statement that juveniles were white and Finsch's (1880) noting of an individual of the "white form" in Kahalui are problematical (Bryan & Greenway 1944, Bryan 1958), and may refer to leucistic night-herons or other heron or egret species. Based on these unsubstantiated reports "Reef Heron" was included for Hawaii by Peterson (1961, Appendix II). Reports of white herons at Hilo, Hawai’i in the late 19th century (Henshaw 1902) and Pearl Harbor, O’ahu 14 Feb 1965 (E 25:82), and of dark herons at Pearl Harbor in Jan 1967 during a DOFAW Waterbird Survey (see Little Blue Heron) and at Aimakapa Pond, Hawai’i in Mar 2002, were suggested as being Pacific Reef-Herons but all of these could easily pertain to other egrets or herons (see also Snowy Egret).

Reptiles, Birds, and Mammals of Pakin Atoll, Eastern Caroline Islands
Micronesica 29(1): 37-48 , 1996 Reptiles, Birds, and Mammals of Pakin Atoll, Eastern Caroline Islands DONALD W. BUDEN Division Mathematics of and Science, College of Micronesia, P. 0 . Box 159 Kolonia, Polmpei, Federated States of Micronesia 96941. Abstract-Fifteen species of reptiles, 18 birds, and five mammals are recorded from Pakin Atoll. None is endemic to Pakin and all of the residents tend to be widely distributed throughout Micronesia. Intro duced species include four mammals (Rattus exulans, Canis fami/iaris, Fe/is catus, Sus scrofa), the Red Junglefowl (Gallus gal/us) among birds, and at least one lizard (Varanus indicus). Of the 17 indigenous birds, ten are presumed or documented breeding residents, including four land birds, a heron, and five terns. The Micronesian Honeyeater (My=omela rubratra) is the most common land bird, followed closely by the Micro nesian Starling (Aplonis opaca). The vegetation is mainly Cocos forest, considerably modified by periodic cutting of the undergrowth, deliber ately set fires, and the rooting of pigs. Most of the present vertebrate species do not appear to be seriously endangered by present levels of human activity. But the Micronesian Pigeon (Ducula oceanica) is less numerous on the settled islands, probably reflecting increased hunting pressure, and sea turtles (especially Chelonia mydas) and their eggs are harvested indiscriminately . Introduction Terrestrial vertebrates have been poorly studied on many of the remote atolls of Micronesia, and distributional records are lacking or scanty for many islands. The present study documents the occurrence and relative abundance of reptiles, birds, and mammals on Pakin Atoll for the first time.

Great Egret Ardea Alba
Great Egret Ardea alba Joe Kosack/PGC Photo CURRENT STATUS: In Pennsylvania, the great egret is listed state endangered and protected under the Game and Wildlife Code. Nationally, they are not listed as an endangered/threatened species. All migra- tory birds are protected under the federal Migratory Bird Treaty Act of 1918. POPULATION TREND: The Pennsylvania Game Commission counts active great egret (Ardea alba) nests in every known colony in the state every year to track changes in population size. Since 2009, only two nesting locations have been active in Pennsylvania: Kiwanis Lake, York County (fewer than 10 pairs) and the Susquehanna River’s Wade Island, Dauphin County (fewer than 200 pairs). Both sites are Penn- sylvania Audubon Important Bird Areas. Great egrets abandoned other colonies along the lower Susque- hanna River in Lancaster County in 1988 and along the Delaware River in Philadelphia County in 1991. Wade Island has been surveyed annually since 1985. The egret population there has slowly increased since 1985, with a high count of 197 nests in 2009. The 10-year average count from 2005 to 2014 was 159 nests. First listed as a state threatened species in 1990, the great egret was downgraded to endan- gered in 1999. IDENTIFYING CHARACTERISTICS: Great egrets are almost the size of a great blue heron (Ardea herodias), but white rather than gray-blue. From bill to tail tip, adults are about 40 inches long. The wingspan is 55 inches. The plumage is white, bill yellowish, and legs and feet black. Commonly confused species include cattle egret (Bubulus ibis), snowy egret (Egretta thula), and juvenile little blue herons (Egretta caerulea); however these species are smaller and do not nest regularly in the state.

Snowy Egret Egretta Thula One of California's Most Elegant Birds, The
Herons and Bitterns — Family Ardeidae 133 Snowy Egret Egretta thula One of California’s most elegant birds, the Snowy Egret frequents both coastal and inland wetlands. Since the 1930s, when it recovered from persecution for its plumes, it has been common in fall and winter. Since 1979, it has also established an increasing num- ber of breeding colonies. Yet, in contrast to the Great Egret, the increase in Snowy Egret colonies has not been accompanied by a clear increase in the Snowy’s numbers. Though dependent on wetlands for forag- ing, the Snowy Egret takes advantage of humanity, from nesting in landscaping to following on the heels of clam diggers at the San Diego River mouth, snap- ping up any organisms they suck out of the mud. Breeding distribution: The first recorded Snowy Egret colonies in San Diego County were established at Buena Vista Lagoon in 1979 (J. P. Rieger, AB 33:896, 1979) and Photo by Anthony Mercieca in the Tijuana River valley in 1980 (AB 34:929, 1980). By 1997 these were no longer active, but during the atlas Two of the largest colonies lie near San Diego and period we confirmed nesting at eight other sites. Because Mission bays.

This bird feeds mainly on crayfish, fishes, frogs and insects. It is active in seeking prey and may be seen fluttering over the water or running through the water to catch food. This bird spends much time wading along the water's edge. Like the other herons, its neck is held in an "S" formation during flight with its legs trailing straight out behind its body. It nests with other snowy egrets in a tree colony, called a rookery. Nests contain three to four blue-green eggs. The call of the snowy egret is "wulla-wulla-wulla."

AMERICAN SAMOA In: Scott, D.A
AMERICAN SAMOA In: Scott, D.A. (ed.) 1993. A Directory of Wetlands in Oceania. IWRB, Slimbridge, U.K. and AWB, Kuala Lumpur, Malaysia. A Directory of Wetlands in Oceania AMERICAN SAMOA INTRODUCTION by Richard D. Volk Area: 200.47 sq.km. Population: 47,600 (1990 Census, U.S. Census Bureau). American Samoa is an unincorporated flag territory of the United States. It lies in the central South Pacific approximately 4,160 km south-southwest of Honolulu and 2,880 km northeast of Auckland. The territory consists of seven principal islands: five inhabited high islands, one inhabited atoll and one uninhabited atoll. Covering an area of 135 sq.km and with a population of over 40,000, Tutuila (14°18'S, 170°41'W) is the governmental and economic centre of American Samoa. This island and the small offshore island of Aunu'u are home for 96% of the population. Most of the remaining 4% reside on the three islands of the Manu'a group, Ta'u (44 sq.km), Ofu (8 sq.km) and Olosega (5 sq.km), situated about 130 km east-southeast of Tutuila. Tutuila, Aunu'u and the Manu'a group are high volcanic islands of non-continental origin. They rise precipitously from the ocean, and feature narrow coastal strips of relatively flat land and rugged, mountainous interiors. Only 34% of Tutuila's land area has a slope of less than 30%. The other two principal islands are low-lying atolls: Swain's Island (2.1 sq.km), some 360 km north of Tutuila, and Rose Atoll (8 ha), 260 km east of Tutuila.

Checklist of the Birds of Micronesia Peter Pyle and John Engbring for Ornithologists Visiting Micronesia, R.P
./ /- 'Elepaio, VoL 46, No.6, December 1985. 57 Checklist of the Birds of Micronesia Peter Pyle and John Engbring For ornithologists visiting Micronesia, R.P. Owen's Checklist of the Birds of Micronesia (1977a) has proven a valuable reference for species occurrence among the widely scattered island groups. Since its publication, however, our knowledge of species distribution in Micronesia has been substantially augmented. Numerous species not recorded by Owen in Micronesia or within specific Micronesian island groups have since been reported, and the status of many other species has changed or become better known. This checklist is essentially an updated version of Owen (1977a), listing common and scientific names, and occurrence status and references for all species found in Micronesia as recorded from the island groups. Unlike Owen, who gives the status for each species only for Micronesia as a whole, we give it for -each island group. The checklist is stored on a data base program on file with the U.S. Fish and Wildlife Service (USFWS) in Honolulu, and we encourage comments and new or additional information concerning its contents. A total of 224 species are included, of which 85 currently breed in Micronesia, 3 have become extinct, and 12 have been introduced. Our criteria for-species inclusion is either specimen, photograph, or adequately documented sight record by one or more observer. An additional 13 species (listed in brackets) are included as hypothetical (see below under status symbols). These are potentially occurring species for which reports exist that, in our opinion, fail to meet the above mentioned criteria.

Tuamotu Archipelago, French Polynesia)
PART I. ENVIRONMENT AND BIOTA OF THE TIKEHAU ATOLL (TUAMOTU ARCHIPELAGO, FRENCH POLYNESIA) A. INTES AND B. CAILLART THE REGIONAL BACKGROUND The islands of French Polynesia are scattered throughout a considerable oceanic area located on the eastern boundary of the Indo-Pacific Province. This area stretches from 134"28' W (Temoe Island) to 154"401W longitude (Scilly Island), and from 7"50' S (Motu one Island) to 27"36' S latitude (Xapa Island). Out of the 118 islands constituting French Polynesia, 35 are high volcanic islands and 83 are low-relief islands or atolls. Altogether, the territory of French Polynesia represents an area of 4000 km2 of dry land, 12,000 km2 of lagoonal water and a huge Exclusive Economic Zone (EEZ) covering 5,500,000 km2 of oceanic water (Gabrie and Salvat, 1985). French Polynesia is divided into five archipelagos all oriented parallel to a northwest- southeast axis (Fig. 1). These are the Society archipelago, the Tuamotu archipelago, the Austral archipelago, the Marquesas archipelago and the Gambier archipelago. The Tuamotu archipelago stretches over a distance of 1800 km. Its 76 atolls cover a total area of 13,500 km2 of which 600 km2 are dry land. GEOLOGY OF THE TUAMOTU ARCHEPELAGO As figured by Montaggioni (1985), the Tuamotu atolls cap the top of cone-like volcanoes which rise steeply from the floor of a huge ridge forming wide shelves ranging in depth from 1,500 to 3,000 rn. Geomorphological and geochronological evidences support the fact that the formation of the Tuamotu chain is much older than that of other neighboring islands of French Polynesia.

INTERMEDIATE EGRET (Egretta Intermedia) in the ALEUTIAN
NOTES INTERMEDIATE EGRET (EGRETTA INTERMEDIA) IN THE ALEUTIAN ISLANDS, ALASKA STEPHAN LORENZ, Department of Biology, University of Texas at Tyler, 3900 University Blvd., Tyler, Texas 75799; [email protected] DANIEL D. GIBSON, University of Alaska Museum, 907 Yukon Drive, Fairbanks, Alaska 99775; [email protected] The western Aleutian Islands, Alaska, are well known for the occurrence of migrant birds from Asia (Gibson and Byrd 2007). In addition to many Asiatic waterfowl, shorebirds, and passerines, no fewer than six taxa of Asiatic herons have occurred there. Of these herons, the Yellow Bittern (Ixobrychus sinensis), Chinese Egret (Egretta eulophotes), Little Egret (Egretta g. garzetta), and Asiatic subspecies of the Cattle Egret (Bubulcus ibis coromandus) are known from a single record each, while the Indo-Pacific subspecies of the Great Egret (Ardea alba modesta) and Old World subspecies of the Black-crowned Night-Heron (Nycticorax n. nycticorax) are both known from multiple occurrences (Gibson and Byrd 2007). To this impressive list can now be added the Intermediate Egret (Egretta i. intermedia). Since the 1970s field biologists have studied nesting seabirds (Procellariidae, Hy- drobatidae, Phalacrocoracidae, Laridae, Alcidae) at Buldir Island (see Byrd and Day 1986), the easternmost of the western Aleutians (at 52° 21' N, 175° 56' E) and the most isolated island in the Aleutian archipelago. During the first weeks following the arrival of the summer 2006 field party, Lorenz and other biologists discovered the carcasses of a total of seven herons—on 25 May an adult Great Egret and an adult Black-crowned Night-Heron, on 28 May a second adult Great Egret, on 30 May an adult Intermediate Egret, and on 7 June three more adult Black-crowned Night-Her- ons.
