From April of 2022 to March of 2023,we investigated the bird diversity in Qingtian Turtle Provincial Nature Reserve by using the transect method. A total of 76 bird species of 36 families, 12 orders were recorded, including 7 species of national second-class key protected birds and 4 species of near threatened (NT) species. In terms of residence types, there were 49 species of resident birds, 16 species of winter migratory birds, 8 species of summer migratory birds and 3 species of traveling birds. In terms of faunal types, there were 44 species of oriental birds, 29 species of palaearctic birds, and 3 species of widely distributed birds. The bird ecotype in reserve was dominated by the songbirds, 45 species were recorded. Shannon Wiener diversity index, Simpson dominance index and Pielou evenness index in the winter were the largest,and Margalef richness index in the autumn was the largest. The four indices in the summer were all the smallest. This study systematically analyzed the diversity characteristics of bird communities in the reserve, which provided scientific references for further protection and management in the reserve.

From September 2019 to August 2020, the study conducted a one-year investigation on bird resources in Beihu National Wetland Park, located in Changchun City, Jilin Province, the seasonal dynamics of bird species, population, bird community diversity and bird community composition were investigated. The main results are as follows: 101 species belonging to 16 orders, 35 families and 6002 individuals were recorded in this study, of which passerine birds were the most, and 62 species (61.39% of the total species) were dominant. The dominant ecological type was songbird (51.97%). The diversity index and evenness index of the total community were 3.84 and 0.832 respectively. Among the four habitats, the diversity index and evenness index of woodland and shrub were the highest; according to the similarity index analysis, the similarity index of forest land, shrub, water area and wetland was the lowest,only 0.10, and that of grassland green belt and office and living area was 0. 40, which is the highest among the four habitats. Based on the analysis of the results, the suggestions for urban landscape planning and construction were put forward. [ABSTRACT FROM AUTHOR]

Bird resources in Zhangheyuan Nature Reserve was investigated using samples point method and line transect method from July 2018 to September 2019. Based on field investigation data and previously reported data, 181 bird species were recorded in this Nature Reserve, belonging to 15 orders, 46 families, and 118 genera. Among which, 4 species were first class protected birds, 38 species were second class protected birds at the country level, and 25 species were threatened birds in the Red List of China's Vertebrates. There were 77 species having an oriental distribution, 61 species having a palaearctic distribution, and 43 species having a widespread distribution, respectively. Habitat analysis showed that the order of habitat types from highest biodiversity to lowest biodiversity was forest (4.965)> shrub (4.573)> farmland (3.217)>water area (2.237)>residential area (1.651). The similarity between forest and shrub was highest, while the similarity between forest and water area was lowest. The study enriched the basic data of bird resource diversity in Jingshan Mountains, and provided scientific basis for bird resource protection in Zhangheyuan Nature Reserve. [ABSTRACT FROM AUTHOR]

The published literature on the bird diversity in Guangxi Nature Reserve were collected by literature collection method, and the differences of bird composition and diversity among different nature reserves were analyzed based on G-F index. Taking Nonggang National Nature Reserve as the center, the similarity of bird composition in different nature reserves were analyzed, and the influences of the distance and area of the nature reserves on the bird similarity were discussed. The literature of the birds in 10 nature reserves were collected, it was found that there were significant differences in the number of species, the number of families each order, the number of genera each family, F index, G index and G-F index among different nature reserves (P<0. 001). G-F index in Damingshan National Nature Reserve and Mulun National Nature Reserve were higher (0. 86). The similarity index between Bangliang National Nature Reserve and Nonggang Nature Reserve was the highest (0. 89), and the similarity index between Mulun National Nature Reserve and Nonggang Nature Reserve was the lowest (0. 30). The number of the same species of the birds in each nature reserve had a significant positive correlation with the similarity index(r = 0. 865, P = 0. 003), and it had no significant correlation with the distance from Nonggang Nature Reserve ( r = -0. 059, P = 0. 881) and the area ( r = -0. 400, P = 0. 981), indicating that the similarity index of birds was only affected by the number of the same bird species in each nature reserve. The results of cluster analysis showed that G-F index of the birds in the 10 nature reserves were divided into three categories. [ABSTRACT FROM AUTHOR]

From 2016 to 2019, we investigated species diversity and oommunity structure of wetland birds in Ordos Gull National Nature Reserve, and monitored the water quality annually. A total of 51 bird species, belonging to nine orders and 13 families, were recorded in the reserve, including 23 summer migratory birds, 24 traveling birds and four resident birds. In terms of ornithology, there is one Palaearctic bird species and 50 widely distributed species. The species richness, diversity and evenness indices of wetland bird community decreased from 2016 to 2018, and slightly increased in 2018, but did not recover to the initial level. Water quality analysis showed that the overall water quality in the reserve was poor. Although there is no significant correlation between bird diversity and the change of comprehensive indicators of pollutants, a series of environmental projects implemented since 2018 have achieved significant outcomes, improving the ecological environment of wetlands and reversing the degradation of wetland bird population.

Urban park green space is an important physical part of urban ecosystem, and also, the important habitat and carrier for birds and other animals. Rapid urbanization induces the great change in the spatial pattern of urban park green space, while the patched distribution of urban park green space has the habitat features similar to 'habitat islands', giving obvious effects on urban avian communities. In order to understand the bird species distribution and species diversity in Loudi City and to provide the basic information for the bird conservation, a line transect method and a quadrat sampling method were adopted to investigate the distribution pattern and species richness of the birds across seven urban parks in the Loudi City from November, 2010 to January, 2012. A total of 56 birds species belonging to 11 orders and 27 families were recorded, among which, there were 32, 12 and 12 species belonging to resident birds, summer migrant birds and winter migrant birds, accounting for 57. 2%, 21. 4% and 21. 4%, respectively. As for the fauna, there were 27, 14, and 15 bird species belonging to oriental species, palaearctic species and widely distributed species, accounting for 48. 2%, 25.0% and 26. 8%, respectively. A total of 7 species belonging to the second class of the national key protected species were recorded, accounting for 12. 5% of the total. The Shannon, Pielou and G-F indices of the bird communities in the urban parks in Loudi City were 1. 49, 0. 85 and 0. 62, respectively. Zhushan Park had the highest species number (42), Shannon index (1. 41), G index (3. 46), F index (6. 12) and G-F index (0. 43), and Yueqin Hill Park had the highest Pielou index (0. 92). The reasons of the poor bird species in Loudi City were analyzed, and some suggestions for preventing the birds were put forward. [ABSTRACT FROM AUTHOR]

Although forest gap ecology is an important field of study, research remains limited. By plot setting and point counted observation, the response of birds to forest gaps in winter as well as bird distribution patterns in forest gaps and intact canopies were studied in a north tropical monsoon forest of southwestern China from November 2011 to February 2012 in the Fangcheng Golden Camellia National Nature Reserve, Guangxi. The regression equation of bird species diversity to habitat factor was Y1=0.611+0.002 X13+0.043 X2+0.002 X5-0.003 X8+0.006 X10+0.008 X1 and the regression equation of bird species dominance index to habitat factor was Y3=0.533+0.001 X13+0.019 X2+0.002 X3-0.017 X4+0.002 X1. There were 45 bird species (2 orders and 13 families) recorded in the forest gap, accounting for 84.9% of all birds (n=45), with an average of 9.6 species (range: 2-22). Thirty-nine bird species (5 orders and 14 families) were recorded in non-gap areas, accounting for 73.6% of all birds (n=39), with an average of 5.3 species (range: 1-12). These results suggested that gap size, arbor average height (10 m from gap margin), arbor quantity (10 m from gap margin), shrub quantity (10 m from gap margin), herbal average coverage (1 m from gap margin) and bare land ratio were the key forest gap factors that influenced bird diversities. On the whole, bird diversity in the forest gap was greater than in the intact canopy. Spatial distributions in the forest gaps were also observed in the bird community. Most birds foraged in the "middle" and "canopy" layers in the vertical stratification. In addition, "nearly from" and "close from" contained more birds in relation to horizontal stratification. Feeding niche differentiation was suggested as the main reason for these distribution patterns.
