Dans cet article, nous présentons des données sur la répartition et l’écologie de la reproduction de trois espèces, le Goéland railleur Chroicocephalus genei, la Sterne naine Sternula albifrons et la Sterne pierregarin Sterna hirundo, en Algérie. Pour le Goéland railleur, la plus ancienne colonie connue et de nouveaux sites de reproduction à travers le pays sont documentés. À l’inverse de cette répartition étendue, la Sterne naine et la Sterne pierregarin sont confinées chacune à un seul site de reproduction. Des réflexions sur la sélection des sites de reproduction, la compétition interspécifique et les paramètres de reproduction sont présentées alors que les facteurs affectant négativement la reproduction sont discutés.

Suborder LARI: Skuas, Gulls, Terns and Skimmers Condon (1975) and Checklist Committee (1990) recognised three subfamilies within the Laridae (Larinae, Sterninae and Megalopterinae) but this division has not been widely adopted. We follow Gochfeld & Burger (1996) in recognising gulls in one family (Laridae) and terns and noddies in another (Sternidae).

Most recommendations from a new study of tern and noddy relationships, based on mtDNA (Bridge et al. 2005), have already been adopted by the Taxonomic Subcommittee of the British Ornithologists’ Union Records Committee (Sangster et al. 2005) and the American Ornithologists’ Union Committee on Classification and Nomenclature (Banks, R.C. et al. 2006). This follows many years of disagreement about the generic classification of terns for which 3–12 genera have recently been used (see Bridge et al. 2005).

  • Gelochelidon Nilotica) Nest Survival in Artificial Coastal Saltpans, Bohai Bay, China
    Predictors of Gull-billed tern (Gelochelidon nilotica) nest survival in artificial coastal saltpans, Bohai Bay, China Fuxing Wu1,2, Weipan Lei1, Huw Lloyd3 and Zhengwang Zhang1 1 Ministry of Education Key Laboratory for Biodiversity Sciences and Ecological Engineering, College of Life Sciences, Beijing Normal University, Beijing, China 2 Fujian Provincial Key Laboratory of Marine Ecological Conservation and Restoration, Third Institute of Oceanography, Ministry of Natural Resources, Xiamen, Fujian, China 3 Department of Natural Sciences, Manchester Metropolitan University, Manchester, United Kingdom ABSTRACT Background. Coastal saltpans are a common supratidal human-modified wetland habitat found within many coastal landscape mosaics. Commercial salt production and aquaculture practices often result in the creation of exposed coastal substrates that could provide suitable breeding habitat for waterbird populations; however, few studies have quantified waterbird breeding success in these artificial wetlands. Methods. Here we examine the nesting behavior of the Gull-billed tern (Gelochelidon nilotica) breeding in the Nanpu coastal saltpans of Bohai Bay, Yellow Sea, China over three consecutive nesting seasons (2017–2019) by using nest survival model in Program MARK. Results. The results revealed that nest survival of Gull-billed terns in coastal saltpans (0.697) was higher than previously published estimates from other regions, with an estimated daily survival rate (DSR) of 0.982 ± 0.001 (±95% CI). High nest survival was mainly attributed to low levels of human disturbances and low predation rates, while exposure to strong winds, flooding and silting were the main factors causing nest failure. Model-averaged estimates revealed that eggs laid in nests located on `habitat Submitted 21 May 2020 islands' with feather or clam shell substrates were most likely to hatch.

  • Kenya: Birds and Other Wildlife, Custom Trip Report
    Kenya: Birds and Other Wildlife, custom trip report August 2014 Silvery-cheeked Hornbill www.birdingecotours.com [email protected] 2 | T R I P R E P O R T Custom Tour Kenya August 2014 Kenya lies across the equator, ranging in altitude from 5199 m to sea level. The country’s topography and climate are highly varied, hence it exhibits many different habitats and vegetation types. Huge populations of wildlife are concentrated in protected areas, mainly national parks, national reserves, and conservancies. However, there are also opportunities to find a wealth of biodiversity in non-protected areas, as for example in Important Bird Areas (IBAs), some of which are found in non-protected areas, while others are located in protected areas. The IBAs provide a good chance to see some of the national or regional endemic species of both flora and fauna. They also provide opportunities for visitors to interact with local populations, which might be sharing their knowledge of indigenous life and traditional lifestyles. Our 15-day safari took us through unique and pristine habitats, ranging from the coastal strip of the Indian Ocean and its dry forest to the expansive savanna bushland of Tsavo East National Park, the semiarid steppes of Samburu National Park in northern Kenya, the mountain range of the Taita Hills, tropical rainforests, and Rift Valley lakes, before ending in the Masai Mara in southwestern Kenya. The variance of these habitats provided unique and rich wildlife diversity. Nairobi The city of Nairobi has much to offer its visitors. The Nairobi National Park is just seven kilometers away from the city and offers lots of wildlife.

  • 146 NESTING of SOOTY TERNS (Onychoprion Fuscatus) in THE
    146 NOTES Florida Field Naturalist 37(4):146-148, 2009. NESTING OF SOOTY TERNS (Onychoprion fuscatus) IN THE EASTERN PANHANDLE OF FLORIDA JOHN MURPHY 766 Alligator Drive, Alligator Point, Florida 32346 In 2007 and 2008, a pair of Sooty Terns (Onychoprion fuscatus) nested on the St. George Island causeway, Franklin County, Florida. These occurrences are the second and third breeding records of this species for the county. The Sooty Tern is a widespread species of tropical oceans. The only large breeding colony (25,000-40,000 pairs) in Florida is on Bush Key at Dry Tortugas National Park, Monroe County (Robertson and Robertson 1996), though historical records list isolated breeding at Key West (Monroe County), Tampa Bay (Hillsborough County), and Frank- lin County (AOU 1983). Extralimital breeding, while not uncommon, is frequently short-lived and involves a small number of pairs (Schreiber et al. 2002). The causeway, located at 29°41’ 44.91” N, 84°53’ 7.88” W, is a sand-and-shell island constructed in 1965 as part of the Bryant Patton Bridge, which served as the thorough- fare between St. George Island and mainland Franklin County. In 2004 a new bridge was opened and with the removal of the old bridge spans the island became inaccessible except by watercraft. The causeway is 1.6 km long, with an area of approximately 20 ha (Pranty 2002), and about 2.1 km from the mainland. It is sparsely vegetated with vari- ous salt-tolerant grasses and forbs. It accommodates a number of breeding larids includ- ing Laughing Gulls (Leucophaeus atricilla), Caspian (Hydroprogne caspia), Royal (Thalasseus maximus), Sandwich (T.
