  • The Genus Sula in the Carolinas: an Overview of the Phenology And
    h Gn Sl n th Crln: An Ovrv f th hnl nd trbtn f Gnnt nd b n th Sth Atlnt ht DAVID S. LEE and J. CHRISTOPHER HANEY Five of the eight recognized species of the genus Sula are known from the southeastern United States. Of these only the Northern Gannet (Sula bassana) occurs regularly in the Carolinas, but both the Masked Booby (S. dactylatra), formerly Blue- faced, and the Brown Booby (S. leucogaster) have been reported from North and South Carolina. Of the two remaining species, the Red-footed Booby (S. sula) is generally restricted to the Caribbean and disperses northward into the Florida Keys and Gulf of Mexico, whereas the Blue-footed Booby (S. nebouxii) is an eastern Pacific species with one accidental and astonishing record from south Padre Island, Texas (5 October 1976, photograph Amer. Birds 31:349-351). Generally the records for locally occurring Sula, excluding wintering Northern Gannets, are less than adequate as conclusive evidence of seasonal or geographical occurrence. Most problems result from confusing plumages of the various species and the general lack of experience of North American bird students with boobies. An additional problem is the fact that until very recently most ornithologists believed that boobies occurred off the south Atlantic states, outside Florida, only as rare accidentals, causing many records to be viewed with excessive caution and skepticism. Potter et al. (1980), for example, associated all records of boobies in the Carolinas with storms. In recent years few groups of birds have caused as many interpretive problems for the Carolina Bird Club's North Carolina Records Committee as have the Sula.

  • COCONUT CRAB (Birgus Latro) SURVEYS on PAGAN, COMMONWEALTH of the NORTHERN MARIANAS ISLANDS
    COCONUT CRAB (Birgus latro) SURVEYS ON PAGAN, COMMONWEALTH OF THE NORTHERN MARIANAS ISLANDS Prepared by: Scott Vogt Wildlife Biologist U.S. Navy Naval Facilities Engineering Far East Command Yokosuka, Japan December 2010 INTRODUCTION The coconut or robber crab (Birgus latro) has a wide distribution ranging from Eastern Africa, through the Indian Ocean islands to the Pacific Ocean islands (Fletcher and Amos, 1994). Due to its large size, ease of collection and palatable flesh, the coconut crab is often over-harvested when it occurs in the vicinity of human habitation. The Mariana Islands are no exception and this species is heavily harvested as a cultural resource. Surveys on Guam (USFWS, 2001), Saipan (Kessler, 2006) and Tinian (U.S. Navy, 2008) have documented over-harvested populations. Coconut crabs are a type of hermit crab; however they abandon the necessity of residing in a discarded snail shell at a small size and go through life with no added protection other than their own carapace. They are the largest land dwelling invertebrate in the world and can reach a weight in excess of 5kg. Coconut crabs breed on land but the female releases the eggs in the ocean where they immediately hatch. The oceanic larval stage lasts 2-3 weeks (Fletcher and Amos, 1994). Once on land the growth rate is slow and it is estimated to take 8-10 years to reach the CNMI legal size limit of 3 inches (76mm) across the back (Brown and Fielder, 1991). On the southern islands (Rota, Saipan Tinian and Aguiguan), the Commonwealth of the Northern Mariana Islands – Division of Fish & Wildlife has established a legal crab hunting season from September 15 - November 15.

Nazca Booby Sula granti and Brewster’s Brown Booby Sula leucogaster brewsteri in the Hawaiian Islands and Johnston and Palmyra atolls. Marine Ornithology 36: 67–71. Nazca Booby (Sula granti) and Brewster’s Brown Booby (S. leucogaster brewsteri) are tropical sulids that normally occur only in the eastern Pacific Ocean. In this paper, we report on recent observations of Nazca Booby and Brewster’s Brown Booby in the Hawaiian Islands, including the first apparent nesting records, and we summarize other occurrences of these taxa in the Hawaiian Islands and Johnston and Palmyra Atolls. Genetic research has shown significant population structure between Brown Boobies in the eastern and central Pacific, but little population structure in Masked Boobies (S. dactylatra), indicating that the Eastern Pacific Basin has served as a dispersal barrier in Brown Boobies but not in Masked Boobies. Recent observations of brown-headed male Brown Boobies from the central Pacific nesting on Isla San Benedicto near Mexico indicate that some eastward dispersal is now occurring.

  • Invertebrates Recorded from the Northern
    MARIANA ISLANDS BIODIVERSITY. Short-horn grasshoppers Phylum: Arthropoda Class: Insecta Order: Orthoptera Suborder: Caelifera Superfamilies: Tetrigoidea and Acridoidea. Diversity Micronesia – 23 species, Mariana Isl. – 10 species, CNMI - 9 species Ecological and human significance Short-horn grasshoppers are herbivores usually living in open grassy or weedy areas. Although they have been implicated in crop damage, such as maize, severe damage usually occurs only when there is a buildup of numbers, such as that occurring sometimes with the locust (Locusta migratoria). It is unlikely that any of the grasshoppers are indigenous to the Northern Mariana Islands as they are dwellers of open grassland or of, at least, low-cover, open areas. It is probable that most of the islands were mostly covered by forest prior to the advent and influence of man. It does seem that Stenocatantops splendens has recently entered the Northern Marianas, as , although it is now common on Saipan, there were no records prior to the recent (2000) collected material. It is a moderately sized animal and unlikely to be missed by collectors. Heteropternis obscurella seems, similarly, to have recently colonised the CNMI although its presence on Sarigan indicates a longer occupation period. Both species are in the University of Guam collection but were not recorded by Kevan et al 1997 from the Marianas. Conservation There are no conservation issues recognised at present, and none can really be determined until a thorough survey of the areas has been undertaken. All remaining natural habitats need to be conserved as much as possible. Identification There are no keys for in house identification, specimens have been sent (2002) to Dr.

  • OF the TOWNSVILLE REGION LAKE ROSS the Beautiful Lake Ross Stores Over 200,000 Megalitres of Water and Supplies up to 80% of Townsville’S Drinking Water
    BIRDS OF THE TOWNSVILLE REGION LAKE ROSS The beautiful Lake Ross stores over 200,000 megalitres of water and supplies up to 80% of Townsville’s drinking water. The Ross River Dam wall stretches 8.3km across the Ross River floodplain, providing additional flood mitigation benefit to downstream communities. The Dam’s extensive shallow margins and fringing woodlands provide habitat for over 200 species of birds. At times, the number of Australian Pelicans, Black Swans, Eurasian Coots and Hardhead ducks can run into the thousands – a magic sight to behold. The Dam is also the breeding area for the White-bellied Sea-Eagle and the Osprey. The park around the Dam and the base of the spillway are ideal habitat for bush birds. The borrow pits across the road from the dam also support a wide variety of water birds for some months after each wet season. Lake Ross and the borrow pits are located at the end of Riverway Drive, about 14km past Thuringowa Central. Birds likely to be seen include: Australasian Darter, Little Pied Cormorant, Australian Pelican, White-faced Heron, Little Egret, Eastern Great Egret, Intermediate Egret, Australian White Ibis, Royal Spoonbill, Black Kite, White-bellied Sea-Eagle, Australian Bustard, Rainbow Lorikeet, Pale-headed Rosella, Blue-winged Kookaburra, Rainbow Bee-eater, Helmeted Friarbird, Yellow Honeyeater, Brown Honeyeater, Spangled Drongo, White-bellied Cuckoo-shrike, Pied Butcherbird, Great Bowerbird, Nutmeg Mannikin, Olive-backed Sunbird.

The Service is not proposing critical habitat for these species at this time. The Service identified 16 species of plants and animals as endangered, including the Mariana wandering butterfly, Langford’s tree snail, and the Mariana subspecies of the Pacific sheath-tailed bat. These 16 species are at risk of extinction because of habitat loss and degradation related to development and other activities, the effects of nonnative species (i.e., through habitat degradation, predation, and herbivory), and vulnerability as a consequence of reduced population size and distribution. Seven plant species are identified as threatened, including four species of orchid and a cycad (Cycas micronesica). “These 23 species are facing tremendous challenges with shrinking habitat and the onslaught of invasive species,” said Kristi Young, the Service’s acting field supervisor for the Pacific Islands Fish and Wildlife Office. “Most of these species are known only to Guam and CNMI. It’s imperative we continue to work with Guam and CMNI leadership, federal agencies, and our partners to save these important plants and animals.” The Service re-evaluated the proposed status for several plant species based on new data received from CNMI Department of Land and Natural Resources biologists and the public during the comment periods.
