Biodiversity—The Birds and the Bees and Healthy Grasslands

XXV International Grassland Congress (IGC 2023), 2023
Losses in biodiversity abound in modern agroecosystems, and biodiversity loss hampers ecosystem function and primary productivity comparable to abiotic stress. One of the most endangered ecosystems in the world is North American tallgrass prairie, and native birds and pollinators that historically depended on tallgrass prairie are in precipitous ...

Nocturnal Singing in Grassland Birds

The Wilson Bulletin, 2000
Abstract We conducted unlimited radius point counts from March–July 1999 at sunrise, dusk, and night to document the relative frequency of nocturnal singing by grassland birds at Prairie Ridge State Natural Area, Jasper County, Illinois. Most grassland species were recorded singing at all times of day, but least commonly at night.

Grassland bird communities on conservation and marginal grasslands in an agricultural landscape

Agriculture, Ecosystems & Environment, 2014
Six years of point count data in eastern Nebraska and western Iowa, USA, were used to investigate how the community structure of grassland birds and the densities of four focal species (common yellowthroat, dickcissel, grasshopper sparrow and sedge wren) varied on conservation lands with differing management strategies (i.e., warm- versus cool-season ...

Grasslands as a bird habitat

2009
Grassland bird 'communities' are composed of a mixture of species that require a certain openness. Bird species can be assigned to certain habitat types based on their selection of breeding or feeding habitat at a certain point of their annual life cycle, despite of the relatively wide range of habitats they may use. Steppic grasslands hold 43 priority

Remaining large grasslands may not be sufficient to prevent grassland bird declines

Biological Conservation, 2008
Abstract Grassland birds are in steep decline throughout many regions of the world. In North America, even some common species have declined by >50% over the last few decades. Declines in grassland bird populations have generally been attributed to widespread agricultural conversion of grasslands; more than 80% of North American grasslands have been ...

Grasslands and migratory birds of the Himalayan region

Indian Journal of Forestry, 2016
The Himalayan grasslands from sub-tropical to temperate, alpine and steppe have been exploited historically by humans for multiple uses including grazing lands for livestock. Besides domestic and wild animals, a large number of migratory birds use these grasslands and wetland areas dotted in these grasslands during their vertical and horizontal ...

Pattern and Process in Grassland Bird Communities

Ecological Monographs, 1973
Variations in abundance and distribution of bird species and avifaunal and community organization at regional, local, and within—plot levels were studied during 1969 and 1970 at a shortgrass prairie in Colorado and during 1970 at six additional International Biological Program (IBP) grassland sites.
