Nordmann's Greenshank Population Analysis, at Pantai Cemara Jambi
Final Report Nordmann’s Greenshank Population Analysis, at Pantai Cemara Jambi Cipto Dwi Handono1, Ragil Siti Rihadini1, Iwan Febrianto1 and Ahmad Zulfikar Abdullah1 1Yayasan Ekologi Satwa Alam Liar Indonesia (Yayasan EKSAI/EKSAI Foundation) Surabaya, Indonesia Background Many shorebirds species have declined along East Asian-Australasian Flyway which support the highest diversity of shorebirds in the world, including the globally endangered species, Nordmann’s Greenshank. Nordmann’s Greenshank listed as endangered in the IUCN Red list of Threatened Species because of its small and declining population (BirdLife International, 2016). It’s one of the world’s most threatened shorebirds, is confined to the East Asian–Australasian Flyway (Bamford et al. 2008, BirdLife International 2001, 2012). Its global population is estimated at 500–1,000, with an estimated 100 in Malaysia, 100–200 in Thailand, 100 in Myanmar, plus unknown but low numbers in NE India, Bangladesh and Sumatra (Wetlands International 2006). The population is suspected to be rapidly decreasing due to coastal wetland development throughout Asia for industry, infrastructure and aquaculture, and the degradation of its breeding habitat in Russia by grazing Reindeer Rangifer tarandus (BirdLife International 2012). Mostly Nordmann’s Greenshanks have been recorded in very small numbers throughout Southeast Asia, and there are few places where it has been reported regularly. In Myanmar, for example, it was rediscovered after a gap of almost 129 years. The total count recorded by the Asian Waterbird Census (AWC) in 2006 for Myanmar was 28 birds with 14 being the largest number at a single locality (Naing 2007). In 2011–2012, Nordmann’s Greenshank was found three times in Sumatera Utara province, N Sumatra. -

Ardea Cinerea (Grey Heron) Family: Ardeidae (Herons and Egrets) Order: Ciconiiformes (Storks, Herons and Ibises) Class: Aves (Birds)
UWU The Online Guide to the Animals of Trinidad and Tobago Behaviour Ardea cinerea (Grey Heron) Family: Ardeidae (Herons and Egrets) Order: Ciconiiformes (Storks, Herons and Ibises) Class: Aves (Birds) Fig. 1. Grey heron, Ardea cinerea. [http://www.google.tt/imgres?imgurl=http://www.bbc.co.uk/lancashire/content/images/2006/06/15/grey_heron, downloaded 14 November 2012] TRAITS. Grey herons are large birds that can be 90-100cm tall and an adult could weigh in at approximately 1.5 kg. They are identified by their long necks and very powerful dagger like bills (Briffett 1992). They have grey plumage with long black head plumes and their neck is white with black stripes on the front. In adults the forehead sides of the head and the centre of the crown are white. In flight the neck is folded back with the wings bowed and the flight feathers are black. Each gender looks alike except for the fact that females have shorter heads (Seng and Gardner 1997). The juvenile is greyer without black markings on the head and breast. They usually live long with a life span of 15-24 years. ECOLOGY. The grey heron is found in Europe, Asia and Africa, and has been recorded as an accidental visitor in Trinidad. Grey herons occur in many different habitat types including savannas, ponds, rivers, streams, lakes and temporary pools, coastal brackish water, wetlands, marsh and swamps. Their distribution may depend on the availability of shallow water (brackish, saline, fresh, flowing and standing) (Briffett 1992). They prefer areas with tall trees for nesting UWU The Online Guide to the Animals of Trinidad and Tobago Behaviour (arboreal rooster and nester) but if trees are unavailable, grey herons may roost in dense brush or undergrowth. -

Flamingo ABOUT the GROUP
Flamingo ABOUT THE GROUP Bulletin of the IUCN-SSC/Wetlands International The Flamingo Specialist Group (FSG) was established in 1978 at Tour du Valat in France, under the leadership of Dr. Alan Johnson, who coordinated the group until 2004 (see profile at www.wetlands.org/networks/Profiles/January.htm). Currently, the group is FLAMINGO SPECIALIST GROUP coordinated from the Wildfowl & Wetlands Trust at Slimbridge, UK, as part of the IUCN- SSC/Wetlands International Waterbird Network. The FSG is a global network of flamingo specialists (both scientists and non- scientists) concerned with the study, monitoring, management and conservation of the world’s six flamingo species populations. Its role is to actively promote flamingo research and conservation worldwide by encouraging information exchange and cooperation amongst these specialists, and with other relevant organisations, particularly IUCN - SSC, Ramsar, WWF International and BirdLife International. FSG members include experts in both in-situ (wild) and ex-situ (captive) flamingo conservation, as well as in fields ranging from field surveys to breeding biology, diseases, tracking movements and data management. There are currently 165 members around the world, from India to Chile, and from France to South Africa.

Resource-Dependent Weather Effect in the Reproduction of the White Stork Ciconia Ciconia
Resource-dependent weather effect in the reproduction of the White Stork Ciconia ciconia Damijan Denac1 Denac D. 2006. Resource-dependent weather effect in the reproduction of the White Stork Ciconia ciconia. Ardea 94(2): 233–240. Weather affects the breeding success of White Stork Ciconia ciconia, but the effect has not been studied in the context of different food resources or habitat quality. The aim of this study was to determine whether the impact of weather conditions on breeding success was dependent on habitat quality. The effect of weather on reproduction was analysed in two populations that differed significantly in the availability of suitable feeding habitats. Multiple regression analyses revealed that of the weather variables analysed (average temperature and rainfall in April, May and June), rainfall in May and temperature in June explained a sig- nificant part of the variation in numbers of fledged chicks per pair, but only in the population with poorer food resources. The lack of weather influence in the population with richer food resources was tentatively explained by the larger brood sizes. More effective heat conservation in larger broods, and thus lower chick mortality during cold weather, could be the underlying mechanism for the different response to weather in the two populations.

Courtship and Pair Formation in the Great Egret
COURTSHIP AND PAIR FORMATION IN THE GREAT EGRET Joca• H. Wt•s• THv. reproductivebehavior of the Ardeidaehas receivedconsiderable attention (Verwey 1930; Meanley 1955; Cottrille and Cottrille 1958; Meyerriecks1960 and in Palmer 1962; Baerendsand Van Der Cingel 1962; Blaker 1969a, 1969b; Lancaster 1970). Although Meyerriecks (in Palmer 1962) summarizedthe behavior and McCrimmon (1974) described two sexual displays in detail, the reproductive behavior of the Great Egret (Casmerodiusalbus egretta) remainsessentially unknown.

STLTD¾AREAS AND METIIODS Most of the observations were made at Avery Island, Iberia Parish, Louisiana, 91ø 30' W, 29ø 30• N. Great Egrets nested on five bamboo platforms (ranging from 4 by 20 m to 7 by 35 m, approximate]y) 2 m above the water surface in "Bird City," a 5-ha freshwater pond in the center of the island. Short lengths of bamboo twigs were provided for nest material. The five bamboo platforms supported 430 •-• 15 nesting pairs of Great Egrets in 1974. This number represented a drastic decline from previous years (E. M. Simmons, pets. comm.) and coincidedwith the establishmentof a second heronry 1 km southeast of Bird City. Additional observationswere made at Headquarter Pond, St. Marks National Wildlife Refuge, and Smith Island, Wakulla County, Florida, 84ø 10' W, and 84ø 19• W, 30ø 05' N, and 30ø 03' N, respectively. At Headquarter Pond Great Egrets nested in willows growing in open water more than 0.6 m in depth. The number of nesting egretsdecreased from 38 pairs in 1971 to 9 pairs in 1972 (see below). -

Roseate Spoonbill Breeding in Camden County: a First State Nesting Record for Georgia
vol. 76 • 3 – 4 THE ORIOLE 65 ROSEATE SPOONBILL BREEDING IN CAMDEN COUNTY: A FIRST STATE NESTING RECORD FOR GEORGIA Timothy Keyes One Conservation Way Brunswick, GA 31520 [email protected] Chris Depkin One Conservation Way Brunswick, GA 31520 [email protected] Jessica Aldridge 6222 Charlie Smith Sr. Hwy St. Marys, GA 31558 [email protected] Introduction We report the northernmost breeding record of Roseate Spoonbill (Platalea ajaja) on the Atlantic Coast of the U.S. Nesting activity has been suspected in Georgia for at least 5 years, but was first confirmed in June 2011 at a large wading bird colony in St. Marys, Camden County, Georgia. Prior to this record, the furthest northern breeding record for Roseate Spoonbill was in St. Augustine, St. John’s County, Florida, approximately 100 km to the south. This record for Georgia continues a trend of northward expansion of Roseate Spoonbill post-breeding dispersal and breeding ranges. Prior to the plume-hunting era of the mid to late 1800s, the eastern population of Roseate Spoonbill was more abundant and widespread than it is today (Dumas 2000), breeding across much of south Florida. Direct persecution and collateral disturbance by egret plume hunters led to a significant range contraction between 1850 and the 1890s (Allen 1942), limiting the eastern population of Roseate Spoonbills to a few sites in Florida Bay by the 1940s. A low of 15 nesting pairs were documented in 1936 (Powell et al. 1989). By the late 1960s, Roseate Spoonbills began to expand out of Florida Bay, slowly reclaiming some of the territory they had lost. -
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.
