“…Similar results have been reported in California agroecosystems, where the tree rows at the edges of alfalfa crops significantly increased the avian richness [5]. Other studies support the relevance of isolated trees [64] and hedgerows as factors that favor bird diversity in agricultural landscapes [65][66][67][68][69][70][71][72]. Here, our findings further highlight the relevance of shrub hedgerows for bird communities, documenting the benefits to biodiversity Fig.…”

Background: Understanding the role of agroecosystems as habitat for wildlife is crucial for long-term conservation planning, as different crop stratification and landscape elements can influence bird communities, which are also affected by seasonality. The goal of our study was to determine how agricultural landscapes varying in land cover characteristics affect bird richness and abundance. Bird surveys were conducted at 110 locations within agricultural landscapes in central Chile. The surveyed areas were characterized by land cover at two scales (50 and 500 m radii) through direct observation and photo-interpretation, during winter and spring seasons. Generalized Linear Mixed Models were used to evaluate the effects of different agricultural land covers on bird species and communities. Results: Our results show that birds were more abundant during winter, in particular for insectivorous and granivorous birds, and that bird species richness was significantly increased due to cover provided by hedgerows at the plot scale. Conclusions: We found that abundance of some bird species in agroecosystems in central Chile was higher in winter than in spring, and that overall bird richness was favored by structural diversity including non-crop structures such as hedgerows, which thus may be relevant for improving bird conservation management in temperate agroecosystems. Our results suggest that native vegetation proximity and area may affect seasonal changes in bird communities at larger scales, relationships which warrant further study.

“…Without birds, many of these insects would do considerably more damage to crops and spread diseases, such as West Nile Virus. Birds are also bio-indicators of environmental pollution with DDT contamination being an extreme example [46][47][48]. The birds in our study are generally considered common with some species increasing and others decreasing over time (Table S3).…”

Abstract:Birds are an important part of the agricultural landscape, as having nature value, but also as pest control agents and bio-indicators for the health of the environment. Here we look at linear non-crop elements in agricultural areas as a potential source of food for nestlings of avian species. We measured invertebrate availability as it relates to structural complexity at the local and landscape levels in three counties in central Illinois. Invertebrates were measured with taxonomic diversity, abundance, and estimated biomass during spring of 2012 and 2013. Our study shows that easily modifiable field edge characteristics have the greatest impact on invertebrate diversity and abundance, as compared to field and landscape features. This finding shows that a potential invertebrate food source as measured by both diversity and biomass, may be easily enhanced without changes to agricultural practices.

“…Study of bird diversity gives an estimate of the overall biodiversity of a region, as it occupies almost any habitat (Furness and Greenwood, 1993). Even they respond quickly to any kind of environmental change in and around their habitat and serve as good bioindicators (Padoa-Schioppa et al 2006).…”

Early winter avifaunal diversity from Buxa Tiger Reserve and Rasikbeel Wetland Complex of northern part of West Bengal, India

et al. 2017

The present study was carried out to record the avifaunal diversity and abundance in and around Buxa Tiger Reserve (Raja Bhat Khawa, Buxa Fort, Raimatang and Jayanti) and Rasikbeel Wetland Complex, situated at the northern part of West Bengal, India during 19 th -22 nd November, 2013. A total of 60 bird species belonging to 31 families were identified during four days of study period of which 8 were winter migrants, one was summer migrant and rest were resident. Anthropogenic interventions have altered much of the natural habitat of the present study location; however, a healthy avifaunal diversity was recorded during the present study. More intensive investigations will certainly enrich our knowledge of avian diversity and distribution pattern from the present study location leading to the proper conservation of this important bird area.
