Disney’s Animal Programs Forms Partnership to Preserve the Guam Rail The Island of Guam (found at the southernmost end of the Mariana chain in the South Pacific) is home to a number of bird species that can be found nowhere else in the world. Among them is the Guam Rail (Gallirallus owstoni). This small, grouse-like, flightless brown bird, at one time inhabited the Island’s forest, woodland, scrub and grasslands. Unfortunately, wild populations haven’t been seen since 1986 and it’s believed to be extinct in the wild. Scientists believe this is primarily due to the introduction of the brown tree snake (Boiga irregularis). This tree-dwelling, nocturnal reptile feeds primarily on eggs and young birds and has had a devastating impact on many of Guam’s native birds. But the Guam Rail’s future is not entirely bleak. Since 1987 captive breeding of this species has had great success, thanks to a strong partnership between the field-based Guam Rail Recovery Program, The Department of Aquatic and Wildlife Resources, US Fish and Wildlife Service and the American Zoo and Aquarium Association (AZA) Species Survival Plan (SSP) program. Through this partnership, the Guam Rail SSP has developed an exchange and release program in which captive- hatched birds from U.S. AZA institutions are returned to Guam where they continue to breed and raise offspring in a breeding facility or are released into the wild. To enhance the future of this endangered species, Walt Disney World Animal Programs veterinarians and animal care professionals have formed a unique partnership with the Guam Rail recovery team. During visits to the Island, the Disney team has shared their expertise and skills regarding captive avian care and management while learning more about the management of the species in the wild. The team also completed a health survey of the captive population of rails on Guam, including physical exams, blood and fecal analysis. This is the first medical assessment of this type to be completed since the recovery program began. Information gained from this health survey will enhance the medical care and the ultimate survival of this unique bird both in captivity and in the wilds of Guam. .

Dietary Behavior of the Mangrove Monitor Lizard (Varanus Indicus)
DIETARY BEHAVIOR OF THE MANGROVE MONITOR LIZARD (VARANUS INDICUS) ON COCOS ISLAND, GUAM, AND STRATEGIES FOR VARANUS INDICUS ERADICATION A THESIS SUBMITTED TO THE GRADUATE DIVISION OF THE UNIVERSITY OF HAWAI’I AT HILO IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE IN TROPICAL CONSERVATION BIOLOGY AND ENVIRONMENTAL SCIENCE MAY 2016 By Seamus P. Ehrhard Thesis Committee: William Mautz, Chairperson Donald Price Patrick Hart Acknowledgements I would like to thank Guam’s Department of Agriculture, the Division of Aquatic and Wildlife Resources, and wildlife biologist, Diane Vice, for financial assistance, research materials, and for offering me additional staffing, which greatly aided my fieldwork on Guam. Additionally, I would like to thank Dr. William Mautz for his consistent help and effort, which exceeded all expectations of an advisor, and without which I surely would have not completed my research or been inspired to follow my passion of herpetology to the near ends of the earth. 2 Abstract The mangrove monitor lizard (Varanus indicus), a large invasive predator, can be found on all areas of the 38.6 ha Cocos Island at an estimated density, in October 2011, of 6 V. Indicus per hectare on the island. Plans for the release of the endangered Guam rail (Gallirallus owstoni) on Cocos Island required the culling of V. Indicus, because the lizards are known to consume birds and bird eggs. Cocos Island has 7 different habitats; resort/horticulture, Casuarina forest, mixed strand forest, Pemphis scrub, Scaevola scrub, sand/open area, and wetlands. I removed as many V. Indicus as possible from the three principal habitats; Casuarina forest, mixed scrub forest, and a garbage dump (resort/horticulture) using six different trapping methods.

The Challenges Surrounding Reintroduction Biology
The Challenges Surrounding Reintroduction Biology BY KATIE MORELL 22 www.aza.org | January 2016 January 2016 | www.aza.org 23 Listed as extinct in the wild by the International Union for Conservation of Nature (IUCN), the bird has yet to be reintroduced to its native land, so a satellite home for the species has been created on the neighboring Pacific island of Rota— the place where Newland felt his faith in reintroduction falter, if just for a minute. “On my first trip to Rota, I remember stepping off the plane and seeing a rail dead on the ground at the airport,” he said. “Someone had run over it with their car.” The process of reintroducing a species into the wild can be tricky at best. There are hundreds of factors that go into the decision—environmental, political and © Sedgwick County Zoo, Yang Zhao Yang Zoo, © Sedgwick County sociological. When it works, the results are exhilarating for the public and environmentalists. That is what happened in the 1980s when biologists were alerted to the plight of the California condor, pushed to near extinction by a pesticide called DDT. By 1982, there were only 23 condors left; five years later, a robust breeding and reintroduction program was initiated to save the species. The program worked, condors were released, DDT was outlawed and, according to the U.S. Fish and Wildlife Service (USFWS), as of 2008 there were t was a few years ago when Scott more condors flying in the wild than in Newland felt his heart drop to managed care. his feet.

This legislation changes the officid bird of Guam from the Totot, the Mariana Fruit Dove (Ptilinoppus roseicapilla), to the Ko'ko, the Guam Rail (Gallirallus owstoni). The idea for this change was generated by the Guam Department of Agriculture, which has been involved for a number of years in the effort to preserve and protect the Ko'ko. In fact, the Department of Agriculture had a number of village meetings to determine community feeling, and then their draft legislation was forwarded to the Legislature by the Administration. The Ko'ko has already become something of a symbol for Guam, and was used as a mascot during the South Pacific Games held here last year.

Boiga Irregularis (Brown Tree Snakes) on Guam and Its Effect on Fauna
Boiga irregularis (Brown Tree Snakes) on Guam and Its Effect on Fauna Alexandria Amand Introduction The island of Guam, a U. S. Territory, is located in the tropical western Pacific, nearly equidistant from Japan to the north, the Philippines to the west, and New Guinea to the South (Enbring & Ftitts 1988). The island is longer than it is wide and is divided into a diverse landscape with forests and cliffs in the north and primarily savannas and river valleys in the south (Savidge 1987). Guam is also a land of great biodiversity including small mammals, reptiles, and numerous bird species; however, snakes are not a natural part of this biodiversity. The burrowing blind snake (Rhamphotyphlops braminus), the only native snake to Guam, does not pose a threat to the fauna, yet the introduction of Boiga irregularis (brown tree snake) has threatened the island’s biodiversity. Boiga irregularis a native to Indonesia, New Guinea, Solomon Islands, and Australia, was introduced to Guam by way of navy vessels shortly after World War II where it is an exotic and invasive species (Butler 1997). As a result of its accidental introduction and population explosion, Boiga irregularis is responsible for a loss of biodiversity through predation. Boiga irregualris has had devastating effects particularly on avifauna such as the Guam rail and Guam flycatcher, small mammals including the Mariana fruit bat, and reptiles such as geckos and skinks. This paper will outline the negative impact that Boiga irregularis has had on the biodiversity of Guam, as well as the techniques being used to control the snakes population and discuss their effectiveness.

The draft agreement and proposed permit was published in the Federal Register on January 10. Cocos Island Resort and the Guam Department of Agriculture have applied for an enhancement of survival permit and a proposed Safe Harbor Agreement for the benefit of the ko'ko'. Implementation of the proposed agreement would provide for voluntary habitat restoration, maintenance, and activities to enhance the habitat and recovery of the Guam rail on 83.1 acres of Cocos Island partly owned by Cocos Island Resort, and the Guam Department of Parks and Recreation. “Thanks to the Cocos Island Resort and its cooperators in local and federal governments, wild ko'ko' may once again be seen on Guam,” said Patrick Leonard, field supervisor, Pacific Islands Fish and Wildlife Office. “Voluntary cooperative conservation efforts with the private sector strengthen the efforts of government agencies and help ensure protection of valuable habitat and the recovery of endangered species.” A Safe Harbor Agreement encourages private landowners to conduct voluntary conservation activities and assures them that they will not be subjected to increased endangered species restrictions should their beneficial stewardship efforts result in increased numbers of listed species.

Guam Rail, Endangered Species Bulletin, January/April 2000, Vol
The Rail Road To Recovery by M. Kelly Brock and Grant M. Beauprez The road to recovery for the Guam rail began in December 1989 when we initiated attempts to establish an experimental population of rails on Guam’s neighboring snake-free island of Rota in the Commonwealth of the Image omitted Northern Mariana Islands. Between December 1989 and August 1999, we released 267 captive-reared rails while evaluating the success of different release methods. Control of feral cats in the release area enhanced rail survival and we first documented reproduction by captive-reared rails on Rota in 1995. During the summer of 1999, at least three pairs of captive reared Guam rails successfully produced 5 nests with eggs and hatchlings. Before reintroduction of the rail to its native habitat on the island of Guam could begin, the brown tree snake had to be controlled.
