Winter Bird Population Studies and Project Prairie Birds for Surveying Grassland Birds
Southeastern Naturalist, 2008 We compared 2 survey methods for assessing winter bird communities in temperate grasslands: Winter Bird Population Study surveys are area-searches that have long been used in a variety of habitats whereas Project Prairie Bird surveys employ active-flushing techniques on strip-transects and are intended for use in grasslands.

Risk of Agricultural Practices and Habitat Change to Farmland Birds
Avian Conservation and Ecology, 2011 Many common bird species have declined as a result of agricultural intensification and this could be mitigated by organic farming. We paired sites for habitat and geographical location on organic and nonorganic farms in Ontario, Canada to test a priori ...

Survival of Postfledging Grassland Birds in Missouri [PDF]
The Condor, 2007 Abstract We describe survival patterns during the postfledging period for two species of grassland birds in Missouri. We monitored 155 radio-marked juvenile Dickcissels (Spiza americana) and 107 juvenile Eastern Meadowlarks (Sturnella magna; hereafter meadowlark) in southwestern Missouri, from 2002 to 2004.

Proximate And Landscape Factors Influence Grassland Bird Distributions
Ecological Applications, 2006 Ecologists increasingly recognize that birds can respond to features well beyond their normal areas of activity, but little is known about the relative importance of landscapes and proximate factors or about the scales of landscapes that influence bird distributions.

Grassland bird diversity and abundance in the presence of native and non-native grazers
Avian Conservation and Ecology, 2021 Temperate grassland biomes are globally imperiled, and grassland birds are in precipitous decline as a result. The majority of North America's grassland birds breed on rangelands occupied by domestic cattle, but reintroductions of bison to restore ...
