Here we reviewed 26 GTBs from eight orders. In addition, we summarized here recorded ten GTBs during our 2016 field surveys. Swan geese were most numerous and most frequently sighted of the GTBs with mean 33.8±54.1 counted bird. The Mongolian Avifauna assessed with 476 species of 19 different orders. Twenty-six species (5.1%) out of 476 species had listed in the International Union for Conservation of Nature (IUCN) Red list as GTBs. In addition, there is still huge lack of investigation for GTBs (indeed, whole avifaMANUSCRIPTuna) of Mongolia. Keywords: Globally threatened birds (GTBs), IUCN, Red list INTRODUCTION Mongolia is a vast country with diverse natural zones and landscapes, harboring rich and unique assemblages of birds (Gombobaatar et al, 2011). The country is located at the junction of three migratory flyways, i.e. East Asia Australian, Central Asian and East Africa-West Asia flyways. Over the past decades, Mongolia has undergone significant social and economic changes, and during that time, many groups of birds, including cranes, breeding shorebirds, raptors and some passerines, have experienced rapid declines (Gombobaatar et al, 2011). Categories in theACCEPTED IUCN Red list, i.e. Vulnerable (VU), Endangered (EN), and Critically Endangered (CR) were considered as Globally Threatened species in the IUCN Red List, whereas Near Threatened were not included in GTB. 1 ACCEPTED MANUSCRIPT Foreign scientists have previously studied the Mongolian Avifauna, especially the Russian scientists (including those from the former Soviet Union) conducted basic studies on Mongolian Avifauna during the 19 th and 20 th Centuries (Adiya & Suran, 2008). The previous work included research into the avifauna along the Mongolian-Soviet border area (focusing on Mongol Daguur) which conducted by the Soviet Union’s Institute of Geography. Historical biological expeditions by Mongolia and Germany (between 1962 and 1964) and Mongolia and Russia (since 1970) explored most of the Mongolian avifauna (Adiya & Suran, 2008). Since the second half of the 20 th Century, Mongolian researchers’ roles rapidly increased to study the country’s fauna (Adiya & Suran, 2008) especially in the case of Globally Threatened species. Currently, some surveys on Globally Threatened Birds (GTBs) are being conducted by a joint expedition of Mongolian and foreign scientists in Mongolia. Particularly, migration ecology-flyway, conservation management, and other ecological and biological surveys are being conducted for several GTBs, i.e. Swan Goose (Anser cygniod ), White-napped Crane (Grus vipio ), Steppe Eagle ( Aquila nepalensis ), Great Bustard ( Otis tarda ), and Saker Falcon (Falco cherrug ). The Wildlife Science & Conservation Center of Mongolia (WSCCM) and the Mongolian Ornithological Society (MOS) areMANUSCRIPT participating with major roles for GTBs studies. Further, two major conservation documents for Mongolian birds were titled as: (a) “Directory of Important Bird Areas in Mongolia: KEY SITES FOR CONSERVATION” and (b) “MONGOLIAN RED LIST OF BIRDS” performed by these two organization, respectively. In addition, Ornithological Laboratory of the Mongolian Academy of Science and Department of Biology of Mongolian National University of Education (MNUE) had been playing a significant part for study on GTBs. Furthermore, here we reported ten GTBs belong to four orders which were observed in 2016 Important Bird Area (IBA) survey, performed by research team of MNUE and National Science Museum of Korea (NSMK). In addition, the most part of Mongolian avifauna remain as very poor investigated. As meintioned above,ACCEPTED earlier studies conducted by foriegn scientists and since 1980s by themselves which were focused on some GTBs. Further, there is still a need to expand the birds survyes in Mongolian avifauna to improve understanding their avifauna importance. Our 2 ACCEPTED MANUSCRIPT objective for this paper is to introduce wide opportunities and territory of Mongolian avifauna to the international organizations, individual reseachers as well. STATUS OF MONGOLIAN BIRDS In recent years, international nature conservation organizations are paying attention to the highly diverse Mongolian avifauna. Mongolia is one of the top-priority countries for bird research and conservation as it is located at the junction of three different migratory flyways and contains globally significant breeding grounds for threatened species (Gombobaatar et al, 2011). The main bird habitats in Mongolia comprise of grassland steppe, semi-desert and desert, mountain steppe, high mountains, forested mountains, wetlands and riparian areas (Batbayar et al, 2009). Currently, 476 species of birds had recorded in Mongolia, belonging to 60 families and 19 orders. There are 81 species of resident birds and 395 species of migratory birds. In addition, 310 species of migratory birds breed in Mongolia, ten species are winter visitors from Siberia, nine species are summer visitors and 66 species MANUSCRIPTare vagrants (Bold et al, 2007). The 435 species listed as of Least Concern (LC) in the IUCN Red List, whereas, 14 species listed as Near Threatened (NT), 14 species as Vulnerable (VU), 9 species as Endangered (EN), and three species listed as Critically Endangered (CR) (Figure 1) (Gombobaatar et al, 2011). Twenty-six species GTBs (VU, EN, CR) are belonging to eight different orders (42%) of 19 orders of Mongolia (Figure 2). Population trend of these 26 GTBs is considering still rapidly decreasing across in their global ragnes. Status summaries for GTBs Here we reviewed the 26 GTBs that distributed in Mongolia using historical literature sources (time ranged fromACCEPTED 1930s to 2016). The most part of Mongolian avifauna, especially GTBs and Near Threatened species (NT) are poor investigated through its valuable Mongolian breeding range in the past. Just since 1990s, the investigation of GTBs had been increased at the regional and international research levels. As a result, three (12%) of 26 species became well 3 ACCEPTED MANUSCRIPT studied species in their Mongolian range. Unfortunately, other 23 GTBs (88%) are considered as very poor studied species in their Mongolian range (indeed Eastern and Central Asia). Most of the previous studies were conducted for Raptors (six species) (also known as the birds of prey), especially for their distribution, number, conservation status, breeding, mortality and diet composition. In particularly, Endangered Saker falcon is the most investigated GTB in Mongolia, and this species historically studied by several expeditions such as: Przewalskii (1876); Bianki (1915); Dementiev & Shagdarsuren (1964); Kozlova (1975); Shagdarsuren (1983); Bold et al. (1996); Ellis et al. (1996; 1997); Sumiya & Batsaikhan (1999); Sumiya et al. (2001); Shagdarsuren et al. (2001); and Gombobaatar et al. (1999, 2000a, b, 2001, 2003). In Mongolia, the breeding Saker uses utility poles (n=10 nests), bridges (n=2), old buildings (n=3), track tires (n=1) and rock cliffs, slopes, top of stone pillars and short elms (n= 64 combined) for its nesting site in central and southeast Mongolia (Ellis et al .1997). Further, mortality of GT raptors, i.e. Saker Falcon and the Steppe Eagle (with other raptors) was investigated by several research teams (Harness et al, 2008; Amartuvshin et al, 2012; Batbayat et al, 2017) in eastern and southeast Mongolian steppes where shortage of nesting site. They reported that electrocution could considered as one of the dominant threat for raptors in Mongolia (indeed in their Global RanMANUSCRIPTge IUCN, 2016). During our survey in 2016, we observed seven individuals from seven different localities (Table 2) and we found four electrocuted (dead) birds just in our 10km drive in Bogd soum (village) of Ovorkhangai aimag (province: N44.81- 44.90; E101.92 – 102.00).

Finally, Wing-flapping appears to be used as a display by males, and it is especially conspicuous because each sequence of it is ended by a rapid stretching of both wings over the back in a posture that makes visible the white axillary feathers, which contrast sharply with the black underwing surface. Copulatory behavior. Precopulatory behavior consists of the male swimming up to the female, his neck stretched and his crest de- pressed, and making occasional Bill-dipping movements. He then suddenly begins to perform more vigorous Head-dipping movements, and the female, if receptive, performs similar Bill-dipping or Head- dipping movements.

    Ann. Anim. Sci., Vol. 18, No. 1 (2018) 3–15 DOI: 10.1515/aoas-2017-0016 A MOLECULAR CHARACTERISTIC OF THE ANATIDAE MITOCHONDRIAL CONTROL region – A REVIEW* * Joanna Warzecha♦, Agnieszka Fornal, Maria Oczkowicz, Monika Bugno-Poniewierska Department of Animal Molecular Biology National Research Institute of Animal Production, 32-083 Balice n. Kraków, Poland ♦Corresponding author: [email protected] Abstract Mitochondrial DNA (mtDNA) is a molecular tool that is very effective in genetic research, includ- ing phylogenetic analysis. The non-coding region is the most variable fragment of mtDNA, show- ing variability in length and nucleobase composition and containing three domains: two hyper- variable peripheral regions and the conserved domain (D-loop) in the middle. The Anseriformes are amongst the best studied avian groups, including approximately 150 species and containing geese, swans, ducks (Anatidae), the Magpie goose (Anseranatidae) and screamers (Anhimidae). The most numerous family is the Anatidae, appearing in close relationships within the phyloge- netic branches of the species. There are differences between the non-coding region of the Anatidae in comparison to other avian control regions. In the article presented below the control region sequences and the phylogeny of the Anatidae were reviewed. Key words: mitochondrial DNA, control region, Anseriformes, Anatidae, goose, swan, duck Phylogenetics and the molecular evolution of vertebrates have been widely in- vestigated, particularly by using mitochondrial DNA (Ramirez et al., 1993). Despite its quick evolution, mitochondrial DNA is conservative in length, gene content and organisation. Additionally, it is a commonly used molecular tool in biological identi- fication research, taxonomy and phylogeny in living organisms (Brown et al., 1982; Ramirez et al., 1993; Castro et al., 1998; Slack et al., 2003; Bucheli and Wenzel, 2005).

  • Biological Assessment of Ecologically Important Areas for Bird Taxonomic Group of the Yellow Sea Ecoregion
    Biological Assessment Report of the Yellow Sea Ecoregion (2008) Biological Assessment of Ecologically Important Areas for Bird Taxonomic Group of the Yellow Sea Ecoregion China Part Author: MA Zhijun Position/affiliation: School of Life Sciences, Fudan University Mailing address: No. 220 Handan Road, Shanghai, 200433, P. R. China Email address: [email protected] Ecological sub-regions Definition and description of sub-regions Sub-regions were defined as Palaearctic and Oriental realms according to biogeographical zones of fauna. The Palaearctic realm is the current distribution centre for animals in the cool-temperate zone of the old world, and the Oriental realm is the current distribution center for animals in the tropical zone of Asia. The boundary of these two regions is the Huaihe River. With temperate climate in the north and subtropical climate in the south, the Huaihe River is also the north boundary of most of animals in tropical and subtropical zones. Sub-region 1: Sub-region 1 is the Palaearctic realm; it is defined as the area north of the Huaihe River and includes the Bohai Sea, the Yellow Sea and the northern part of the East China Sea. Most birds in this sub-region are migratory. Sub-region 2: Sub-region 2 is the Oriental realm; it is defined as the area south of the Huaihe River and covers the southern part of the East China Sea. This sub-region contains wintering grounds for birds in the Palaearctic realm. The entire Yellow Sea Ecoregion (YSE) falls into sub-region 1. Common Criteria for Identification of Ecologically Important Areas of the YSE The Bird Taxonomic Group adopted the following common criteria to identify Ecologically Important Areas for birds in the YSE (Table 1).
