This study was conducted to determine the composition of bird diversity and vegetation stages and composition, to determine the variables that most influence the diversity of birds in protected forests Sirimau, This study was conducted for three months from September 2015 to November 2015. Bird observations and habitat variables performed using the Point Count method, and found thirty observation points at each location, with 30 cm trellis and 200 m plot distance. The analysis of birds and vegetation in Sirimau mountain forests shows that, bird species are dominated by Red Eye (Aplonis Motalica), and more than 50 species of vegetation exist in the research location, dominated by fruits.

Number Of Individuals

The study (2007-08) was carried out in Phewa Lake which is one of the largest lake systems in Nepal to evaluate seasonal diversity and population status of waterbirds. A total of 39 waterbird species belonging to 17 families of 5 orders was recorded. The highest number of species (31 species) was found in December and January. Winter was the most diverged season in terms of number of species (35 species) and summer and autumn by 17 species. January had the highest (1584) and September the lowest (345) waterbird population. Out of 39 species, 15 species were winter visitors, 10 resident, and 4 rare winter visitor. The highest diversity ( H =2.6228) was found in February and lowest ( H =1.2014) in June. The value of evenness (Jacob's coefficient) was higher (0.8485) in February and lowest (0.4555) in June. During June, 69.92% (616 individuals) of the total population (881) constituted only Cattle Egret. The dominancy was found highest (C=0.5058) in June and lowest (C=0.1020) in February. The bird communities of summer and autumn were more similar (S=0.7059) than the summer and winter (S=0.5). The fluctuation in number of individuals of bird species was found unrelated to seasons (months) (F=1.71, df = 8, 342, P ≤ 0.05). The species richness was found different in different seasons (months) (Χ2=29.34, df = 8, P ≤ 0.05). Detail study of bird diversity and population status with periodic monitoring in Phewa Lake is recommended for their conservation and management as a whole.

We present the results of short ornithological observations conducted in November–December 2014 and December 2015 in the territory near Putao in northern Myanmar at elevations below 1,500m.  We recorded 105 species, which were mostly resident birds, and evaluated the species abundance with a relative scale along tourist walking routes in the area.  The bird species richness in the Mali Hka River Valley was observed to be less than in the adjacent virgin mountain forests.  Our results could be used for future bird monitoring fieldworks.

Resident Bird

The diversity and population of birds was studied from January, 2011 to December, 2011, once a week regularly. Altogether fifteen species of wetland birds were recorded from Tengra and Budhi rivers. Maximum species were recorded in January and minimum in July and August. Out of total bird species 40% were migratory, 46.67 % were resident, and 13.33 % were winter visitors. On the basis of abundance, there were 46.67% scarce, 33.33% fairly common and 20% common. On the basis of their population status, maximum number belonged to Ardeola grayii species and minimum in Leptoptilos javanicus species. Maximum species of the birds belonged to family Ardeidae. According to statistical analysis, the resident bird were more diversed then migrant and winter visitor respectively. Similarly, resident birds were much evenly distributed then winter visitors and migrant respectively. The study revealed decreasing trend of bird species from previous period. The conversion of wetland into agricultural land and plotting programmes were the main causes to decline the bird species.

AbstractOur study focused on the Taita White-eye Zosterops silvanus, one of three bird species endemic to the Taita Hill forests, south-east Kenya. Formerly considered Critically Endangered, Taita White-eye has been down-listed to Endangered following the findings of this study. Between November 1998 and September 1999 we counted this species along line transects to establish their current population status and distribution in its entire range. White-eye censuses were conducted in nine forest fragments of the Taita Hills and the virtually undisturbed Mt Kasigau forest. The total global population of Taita White-eyes was estimated to be c. 7,100 birds. Mt Kasigau was shown to be the species' main stronghold, maintaining a very high density (26 birds ha−1) and holding 80% (5,600 individuals) of the entire population. In the Taita Hills forests, densities were consistently higher in the small isolated fragments than in the large ones, though the former held only a small population (3% of total). At Mt Sagala, a large isolated block where indigenous trees have been largely replaced with exotic plantation, this species was not encountered. We found no evidence of interchange between the White-eye populations on Mt Kasigau and the Taita Hills forests, probably because of the separation by a low-altitude, dry woodland habitat barrier. While prioritization for conservation action should focus more on the Taita Hills forest fragments, Mt Kasigau should be treated as fragile ecosystem which holds a huge, apparently insular population of Taita White-eyes.

<p>Mount Rinjani area on the island of  Lombok is unique in bioecology. It provides habitats for many species of birds, especially birds of Wallacea. Several studies  on birds in this area have been done, but the conservation priority of these birds has not been determined. Based on this condition, the purpose of this research is to determine the priority of birds conservation in mount Rinjani areas. Exploration about the spesies of birds was started from Senaru Village to Segara Anak Lake. Abundance of each bird species was estimated using point count. Data analysis to determine the conservation priority used indicators that consist of endemicity, population status, species threatened and species management. The results showed that the birds species in mount Rinjani  areas are composed of 32 species belonging to 20 families. Bird species that have high abundance were <em>Amandava amandava </em>(15.94%), <em>Zosterops Montanus</em> (15.70%), and <em>Parus major</em> (11.32%), while <em>Ptilinopus melanospila</em> and <em>Anthus novaeseelandiae</em> were in low abundance (0.23%). Analysis birds conservation priority  in mount Rinjani areas indicates that <em>Otus jolandae</em> has the highest score (65) and should be the first priority for the conservation, while <em>Philemon buceroides</em> and <em>Gallus varius</em> with the same score (60) are the second priority.<em> </em></p><p><strong>How to Cite</strong></p><p>Hadiprayitno, G., Mertha, I.

Preliminary Study

On April and September 2006, preliminary study to know the distribution, population status and habitat of the Javan moustached parakeets (Psittacula alexandri alexandri Linnaeus 1758) were conducted in the Baluran and Alas Purwo National Parks (East Java) and in the Tilu Geder Mountain Forests and in the Darmaga IPB Campus Parks (West Java). Direct and indirect observations were used in this research. The results are found only 2 individuals of birds in the Darmaga IPB Campus Parks. However, 45 species of plants were recorded as the natural food resources for the Javan moustached parakeets in the fields. Almost 60 percent parts of plants i.e., fruits were food by birds, even if those birds are more frugivorous. Some species of plants were known as the nesting trees for the species, namely: Tectona grandis, Acacia lecophloea, Azadirachta indica, Tetrameles nudiflora and Eucalyptus deglupta. The Javan moustached parakeets have needed mangrove forests, beach forests, evergreen forests and old teak forests for their activities. The population and their habitat of javan parakeets are threatened by forest fragmentation effects and over hunting.
