E-mail: [email protected] Nomascus gabriellae, the yellow-cheeked crested gibbon was identified and scientifically described 100 years ago from a specimen obtained in Vietnam. This paper provides a historical record of how this gibbon was discovered by a young Englishwoman, Gabrielle Maud Vassal, whose name the gibbon carries. Mrs Vassal lived in Nha Trang, Vietnam, with her husband, a scientist working at the Pasteur Institute of Nha Trang with the famous microbiologist Alexandre Yersin. Together they collected a number of important type specimens for the British Museum (Natural History). Introduction Gabriella refers to Gabrielle Maud Vassal (1880- 1959), an Englishwoman born in Uppingham in the The yellow-cheeked crested gibbon (Nomascus county of Rutland (Fig. 2).

With one exception, the eastern hoolock, all ape species and their subspecies are classi- fied as endangered or critically endangered by the International Union for Conservation of Nature (IUCN) (IUCN, 2016c). Since apes require access to forested or wooded land- scapes, habitat loss represents a major cause of population decline, as does hunting in these settings (Geissmann, 2007; Hickey et al., 2013; Plumptre et al., 2016b; Stokes et al., 2010; Wich et al., 2008).

Zoological Studies 51(3): 362-371. The avian communities of Hainan I., China are poorly known and under considerable threat. In our studies at Jianfengling, Hainan I. between May 2000 and Sept. 2004, 117 bird species were recorded using fixed-radius point counts and mist-netting at 3 elevations (200, 500, and 1000 m). Numbers of bird species recorded at the 3 elevations were 67 (200 m), 67 (500 m), and 89 (1000 m), of which 15 species were recorded exclusively at 200 m, 11 at 500 m, and 24 at 1000 m. The highest bird species richness occurred at the highest elevation (1000 m). The pattern of bird species richness differed from those of continental China and the island of Taiwan. Each elevation hosted a unique assemblage of special conservation concern. Species which require mature, full-canopy forest, and are often associated with mixed-species flocks were mainly distributed at 1000 m.

APPROVED BY MEM~ OF THE THESIS COMMITTEE: Marc R. Feldesman, Chairman Gibbon classification at the species and subspecies levels has been hotly debated for the last 200 years. This thesis explores the reasons for this debate. Authorities agree that siamang, concolor, kloss and hoolock are species, while there is complete lack of agreement on lar, agile, moloch, Mueller's and pileated. The disagreement results from the use and emphasis of different character traits, and from debate on the occurrence and importance of gene flow.

Researches on diets and feeding behavior of endangered species are critical to understand ecological adaptations and develop conservation strategies. To document the diet of the Hainan gibbon (Nomascus hainanus) we conducted a long-term dietary composition survey in Bawangling National Nature Reserve, Hainan Island, China from 2002 to 2014. Transects and quadrants were established to monitor plant phenology and to count tree species. Tracking survey and scan-sampling method were used to record the feeding species and feeding time of Hainan Gibbon. Our results showed that Hainan gibbons’ habitat vegetation structure is tropical montane evergreen forest dominated by Lauraceae species while Dipterocarpaceae, Leguminosae and Ficusare rare. Hainan gibbons consume 133 plant species across 83 genera and 51 families. Hainan gibbons consumed more Lauraceae and Myrtaceae plant species than other plant species, whereas their consumption of leguminous species was little and with no Dipterocarpaceae compared to other gibbons. Furthermore, we classified the food plants as different feeding parts and confirmed that this gibbon species is a main fruits eater particularly during the wet season (114 species,64.8% feeding time), meanwhile we also observed five species of animal foods.

    Thailand Highlights 14th to 26th November 2019 (13 days) Trip Report Siamese Fireback by Forrest Rowland Trip report compiled by Tour Leader: Forrest Rowland Trip Report – RBL Thailand - Highlights 2019 2 Tour Summary Thailand has been known as a top tourist destination for quite some time. Foreigners and Ex-pats flock there for the beautiful scenery, great infrastructure, and delicious cuisine among other cultural aspects. For birders, it has recently caught up to big names like Borneo and Malaysia, in terms of respect for the avian delights it holds for visitors. Our twelve-day Highlights Tour to Thailand set out to sample a bit of the best of every major habitat type in the country, with a slight focus on the lush montane forests that hold most of the country’s specialty bird species. The tour began in Bangkok, a bustling metropolis of winding narrow roads, flyovers, towering apartment buildings, and seemingly endless people. Despite the density and throng of humanity, many of the participants on the tour were able to enjoy a Crested Goshawk flight by Forrest Rowland lovely day’s visit to the Grand Palace and historic center of Bangkok, including a fun boat ride passing by several temples. A few early arrivals also had time to bird some of the urban park settings, even picking up a species or two we did not see on the Main Tour. For most, the tour began in earnest on November 15th, with our day tour of the salt pans, mudflats, wetlands, and mangroves of the famed Pak Thale Shore bird Project, and Laem Phak Bia mangroves.

They are highly sensitive to even minor perturbation in ecosystems. Documentation of avian assemblages in different ecosystems is, therefore, becoming increasingly important from environmental monitoring perspective. In absence of comprehensive account of birds of Bibhutibhushan Wildlife Sanctuary, West Bengal, India, we made an attempt to document the birds thriving in this protected area. A total of 102 species of birds belonging to 13 orders and 46 families were recorded during the study period (June 2013 – May 2016). Maximum number of species belong to the order Passeriformes (49 species) and minimum under order Anseriformes (1 species). Among the total bird species, 83 species (81.37%) were resident, 15 species (14.71%) were winter visitor, three species (2.94%) were summer visitor and one species (0.98%) was passage migrant. We noted 38 species of birds (including 36 residents and two summer visitors) to breed within the sanctuary. Analysis of feeding guild data revealed that 46.08% were insectivore, 22.55% were carnivore, 15.69% were omnivore, 6.86% were granivore, 5.88% were frugivore, 1.96% were nectarivore and 0.98% were herbivore. Grey-headed Fish Eagle (Icthyophaga ichthyaetus) and Red- breasted Parakeet (Psittacula alexandri) are two Near Threatened (NT) species designated by IUCN.

Studies about the sound spectrum characteristics and the intergroup differences in eastern black crested gibbon (Nomascus nasutus) song are still rare. Here, we studied the singing behavior of eastern black crested gibbon based on song samples of three groups of gibbons collected from Trung Khanh, northern Vietnam. The results show that: 1) Song frequency of both adult male and adult female eastern black crested gibbon is low and both are below 2 KHz; 2) Songs of adult male eastern black gibbons are composed mainly of short syllables (aa notes) and frequency modulated syllables (FM notes), while adult female gibbons only produce a stable and stereotyped pattern of great calls; 3) There is significant differences among the three groups in highest and lowest frequency of FM syllable in males’ song; 4) The song chorus is dominated by adult males, while females add a great call; 5) The sound spectrum frequency is lower and complex, which is different from Hainan gibbon. The low frequency in the singing of the eastern black crested gibbon is related to the structure and low quality of the vegetation of its habitat.
