Birds play a significant role in many ecosystems by providing a variety of ecological services. Birds eat pests, pollinate flowers, disperse seeds, scavenge carrion, cycle nutrients, and change the environment for the benefit of other species. In this study attempt has been made to record bird diversity at Bahula Dam and its nearby area during January 2020 to June 2021. This is the first avifauna report of Bahula dam and its nearby area. In the survey study total 108 species including water and the land birds were recorded belonging to 16 avifaunal orders and 46 families. Order Passeriformes is dominant in the study area, including 23 families and 44 species (40%), followed by Ciconiformes with 3 families and 11 species (10%), Ansariformes with 1 family and 9 species (8%), Coraciiformes with 4 families and 7 species (6%), Charadriformes with 4 families and 6 species (5%), This survey study represents that species diversity is abundant in spite of many anthropogenic activities. More studies are required to make a complete list of available bird species of this area.

Avifaunal diversity of YS Parmar University of Horticulture and Forestry (YSPUHF) campus was
studied by using Point Count method. Points were selected and point counts were carried on early in
the morning from 6:30 a.m. to 9:00 a.m. and from 4:00 p.m. to 6:00 p.m. in the evening from October
2018 to May 2019. Total 156 species of birds belonging to 16 orders and 52 families were recorded.
Order Passeriformes was found dominant (66.03% occurrence) with 33 family of birds. Order such
as Ciconiiformes, Apodiformes, Falconiformes, Caprimulgiformes were found least occurred (0.64 %
occurrence each) with only one family of bird each. Steppe eagle (Aquila nipalensis H.) and Egyptian
vulture (Neophron percnopterus L.) which fall under Endangered (EN) category of IUCN were observed.
Species like River lapwing (Vanellus duvaucelii L.), Himalayan griffon vulture (Gyps himalayensis
Hume) and Indian alexandrine parakeet (Psittacula eupatria L.) which are near threatened are also
observed. University campus provides comfortable shelter, suitable grounds for foraging, roosting, site
for reproduction and nesting, protection from predation and hostile atmospheric conditions to these
birds. But more efforts should be made to protect endangered and near threatened species of birds in the
region and the country as a whole.

The study was carried out in Vanavarayar Institute of agriculture, Manakkadavu, Pollachi, Tamil Nadu, India during January, 2012 to January, 2013. The institute’s agricultural area classified four different habitats namely, crop land, wetland, plantations, and fallow land. The data were analyzed using Shannon–Wiener function formula; species diversity (H), maximum diversity (Hmax), and evenness (J). Based on this study we found variations in bird population distribution based on the cropping pattern and seasons of the year. Shannon–Wiener Index for diversity richness for different habitats of agroecosystem shows that fallow land recorded highest diversity (3.4619) and maximum diversity index (4.1271) compared to other habitats. Thus, fallow lands are not subject to practices of crop production and therefore supported bird’s nesting and breeding. Thus, most of the birds hunt their food from agricultural field and from water bodies and made their rest place at fallow land; therefore it indicates highest number of species in all the seasons of the year. Rare birds like Indian grey hornbill, yellow - footed green pigeon, common tern, paradise flycatcher, black headed ibis, white browed bulbul, striated heron, and barn owl were observed in particular season shows the richness of the habitats in the study area. The considerable numbers of trees in fallow land and boundary of agricultural land accommodate the large number of bird’s population. Thus planting trees in agricultural lands can increase bird population.

The study revealed a total of 33 wetland bird species belonging to 11 families were recorded from Magadi Bird Sanctuary of Gadag District, Karnataka. Among the family, Scolopacidae dominated the list by the representation of 8 species, followed by the Anatidae with 7 species and least by Laridae, Gruidae, Rallidae, and Recurvirostridae with one species each. Of the total birds recorded based on the density and abundance, Bar-headed geese was found as the dominant species, followed by the Demoiselle Crane, Brahminy Shelduck, Lesser-whistling Duck, Black-headed Ibis, Spot-billed Duck, Black Ibis, and Common Coot, etc., The study also revealed that the lake is a vulnerable wetland harboring plenty of resident as well as few migratory birds. Four globally near threatened species were recorded like Black-headed Ibis (Threskiornis melanocephalus), Painted Stork (Mycteria leucocephala), Black-tailed Godwit (Limosa limosa) and River Tern (Sterna aurantia) have a protected status under the schedule IV of Indian Wildlife Protection Act, 1972. The present study location is also facing tremendous conservation challenges by the impact of anthropogenic alteration of the habitats in and around the lake.

Much has been written both in global and local level on paddy culture, rice production and associated problems, the impact of land use changes, biodiversity in rice fields. However, an area that has received little attention in the Sri Lankan context is the value of rice fields for avifaunal species. There are plenty of studies carried out in rice fields located in temperate, arid and Mediterranean climatic zones while only South America, eastern Asia and India are identified among the tropical countries. Being the 'Granary of the east' and one of the biodiversity hotspots, considerable studies carried out to emphasize the importance of rice fields for avifauna are fewer in Sri Lanka. Thus, this is a comparative appraisal to identify the variations of the utilization of rice fields by avifaunal species in the world, prior to applying the study for the Sri Lankan context.

Este artículo examina la información que se ha producido en revistas arbitradas sobre las aves de las ciudades colombianas, complementando un artículo de revisión Latinoamericano publicado recientemente. Esta revisión identifica un total de 55 artículos en doce ciudades colombianas, lo cual excede en 50 el número de estudios previamente considerado. Los Listados de Especies y los Estudios Ecológicos son los estudios más frecuentes. La ciudad donde más trabajos se han realizado es Medellín (26), seguido por Bogotá (nueve), Cali y Popayán (ambas con cuatro trabajos). Aunque nuestra revisión registra un número mayor de publicaciones de lo que se asumía previamente, concluimos que la ornitología urbana colombiana es todavía una área joven, en tiempo, número, calidad, impacto y profundidad de las investigaciones publicadas hasta el momento.

Feeding ecology of birds was studied in subtropical and temperate region of Doda which lies in middle Himalayan chain of Pir Panchal range of Jammu and Kashmir, India. In the present study, a total 71 species of birds was documented from the study area belonging to 9 orders, 27 families and 12 sub families. Out of 71, 26 species were insectivores (I), 17 omnivores (O), 12 carnivores (C), 4 frugivores (F), 4 grainivores (G) and rest of the 8 species share more than one feeding guilds. This study therefore showed a remarkable variation in feeding ecology of birds in the region surveyed.

Dalmaj area, or Hor Ad-Dalmaj wetlands, is considered as one of the Key Biodiversity Areas (KBAs) and Important Bird Areas (IBAs) in Iraq and the Middle East region due to various ecological values and richness in species and habitat diversity. Dalmaj area includes a wide spectrum
of habitats that ranges of wetlands: open-water lake, reed-beds marsh, marsh margins, mudflats, and the open lake; in addition to the terrestrial habitats that include the arid lands, shrub-lands, and the desert and semi-desert areas. This wide range of habitats in Dalmaj and the surrounding areas have enriched the avifauna and bird diversity. Based on the results of intensive field surveys that extended over more than a decade (in addition to some observations back to 30 years made by MS)
important observations were made on the numbers of the species and their counts in addition to their distribution within the study area where considerable numbers of resident and migrant bird species were observed. This includes 261 of the resident and migrant bird species (breeding and nonbreeding) that have been recorded in Dalmaj wetlands and the surrounding areas. Such a level of richness in bird diversity, which exceeds 60% of the Iraqi bird checklist, illustrates the necessity of
taking the required measures to protect the biodiversity in general and the birds and their habitats in particular in this important hotspot on the national, regional, and global levels. The process of watching the birds and their habitats in Dalmaj for more than a decade has included long-term capacity-building activities that ended in creating a solid, capable national team. The team of the Iraqi Organization for Conservation of nature (IOCN) has contributed to quite extensive surveys in Dalmaj area during the fieldwork. The results of the 30-years surveys presented by this paper represent the most comprehensive work on the avifauna of Dalmaj area and in Iraq as well. The team is confident that this work would contribute positively to the conservation effort in Dalmaj
area.

ABSTRACT To date, there is no updated information of the status of avifauna in Gaya Island. We have conducted a preliminary survey of birds in Gaya Island with the aim to initiate and verify the data of avifauna in Gaya Island that was published 38 years ago. A six days survey was conducted from 28 June to 3 July 2013. The main method used was mist netting. Incidental sightings of bird's species were also recorded. Three existing trails were chosen for the survey. Four mist-nets station at 50m apart were established at each trail. The total sampling effort for mist netting for the whole survey was 45 hours. A total number of 10 species of birds from 7 families were recorded in this study. 5 families and 7 species were captured with mist-nets. The majority of the species collected are from the family of Pycnonotiidae. The result of this preliminary survey provides a general view of the communities of birds in Gaya Island.

El bosque tropical caducifolio (BTC) es uno de los ambientes tropicales con mayor representación en México, pero el grado de deforestación ha hecho que actualmente solo cerca del 30% de la distribución original esté en buen estado de conservación. Las repercusiones de la degradación de este hábitat sobre la avifauna
se observan en la diferencia en la diversidad y en las especies asociadas, ya sea a ambientes conservados o perturbados. Especialmente para el BTC del occidente de México se ha reportado que, en general, las especies migratorias pueden verse
beneficiadas por una perturbación moderada mientras que para las residentes los efectos son negativos. Por este motivo, en el presente trabajo se evaluó la diversidad de especies y su afinidad al tipo de vegetación en un sitio conservado y uno modificado
en la región de Chamela, Jalisco, México, en la temporada de secas de 2005. Los resultados no mostraron diferencias significativas al analizar la ocurrencia de especies entre ambos sitios; sin embargo, la asociación de las especies a cada tipo
de vegetación no fue independiente. Esto podría ser importante para reconocer composiciones de comunidades diferentes que pudieran perdurar por largo tiempo, dado que trabajos previos en el área de vegetación secundaria indican que esta lleva más de 25 años sin que exista regeneración aparente."

The aim of this study was the assessment of species composition and quantitative characteristics of the macrozoobenthic community in the Albanian part of Macro Prespa Lake, and of the environmental state of the lake, based on benthic macroinvertebrates as indicators. Sampling has been carried out in two sites, Gollomboç and Liqenas, in October 2013, from 0,5 m to 10 m depth, using the multihabitat transect method. A " kick and swipe " net has been used for sampling in 0,5 m depth, while in 2 m, 4 m, 6 m and 10 m the samples were taken by a box-corer. A low species richness and low abundance was recorded in the sampling sites. Gastropods were the predominant group regarding the number of species and abundance. Macrovegetation, especially the algal cover of Chara, plays a very important role in the species composition and quantitative characteristics of the macrozoobenthic community in the studied area. The macrozoobenthic community had a low stability and its structure was assessed to be in a " moderate " to " poor " state, based on some stability and diversity indexes. The environmental quality of the lake was predominated by the " poor " to " bad " status, after the WFD categorization.. Environmental indicators based on benthic macroinvertebrates show a tendency for lake eutrophication, nutrients' enrichment and increased organic pollution. However, the lake is still a shelter for many benthic macroinvertebrate species of international concern and of interest for conservation, including endemic species and globally threatened species.

A survey was conducted in Madhav National Park, Shivpuri, Madhya Pradesh (India) from December 2017 to November 2018 to study the impact of seasonal variations in the avifaunal diversity. A total of 123 bird species, belonging to 19 orders and 49 families were observed and identified. The maximum species were observed in the winter season while minimum in the rainy season. The status of the birds was categorized as residential (R), summer migrant (SM) and winter migrants (WM). Out of 123 species, 74 species were resident, 45 species winter migratory and 4 species summer migratory. Passeriformes was the most dominant order, represented by 46 species. This study will definitely help to prepare a seasonal checklist of bird species.

The aim of this study was to investigate the impacts of development (due to tourism) on the understory avifauna in Gaya Island. Three study sites in Gaya Island were selected on three levels of development (based on anthropogenic noise), i.e., Low, Medium and High. Mist netting was performed for three consecutive days at each of the three study sites. Data from this study was analyzed using descriptive and statistical analysis. Correlation analysis was performed to investigate the strength, association and direction between the development levels with the numbers of birds captured. There were a total of 20 birds netted during the survey that consisted of five families from Turdidae, Muscicapidae, Sylviidae, Timaliidae, and Pycnonotidae. Based on the descriptive analysis, the results show a trend of decline in the number of species and the number of individual as the development level (anthropogenic noise) increases. The correlation results indicated a significant association between...
