Narrowness of habitat selection in woodland and grassland birds

open access: yesAvian Conservation and Ecology, 2019
Conservationists have long been concerned about population declines among both woodland and grassland birds, especially those that require extensive areas of a preferred habitat type and avoid mixed habitats.

Remnants of Native Vegetation Surrounding Do Not Affect the Diversity and Density of Birds in Brazilian Grassland-Restoration Sites

open access: yesFrontiers in Ecology and Evolution, 2021
Since in general the surrounding landscape influences the species diversity and abundance in fragments of native vegetation, an amount of native-vegetation cover nearby may also positively affect communities in restored areas, regardless of the sizes of ...

Is Hay for the Birds? Investigating Landowner Willingness to Time Hay Harvests for Grassland Bird Conservation

open access: yes, 2021
Birds in agricultural environments have exhibited steep global population declines in recent decades, and effective conservation strategies targeting their populations are urgently needed.

Identifying mismatches between conservation area networks and vulnerable populations using spatial randomization

open access: yesEcology and Evolution, 2021
Grassland birds are among the most globally threatened bird groups due to substantial degradation of native grassland habitats. However, the current network of grassland conservation areas may not be adequate for halting population declines and ...

A general scenario to evaluate evolution of grassland birds in the Neotropics [PDF]

open access: yes, 2021
Neotropical grassland birds are intimately tied to their habitat and form a phylogenetically diverse group that has been poorly studied from an evolutionary point of view.

Evaluating interactive effects of the Conservation Reserve Program and wind energy infrastructure on grassland bird abundance in the United StatesEvaluating interactive effects of the Conservation Reserve Program and wind energy infrastructure on grassland bird abundance in the United States [PDF]

open access: yesRoyal Society Open Science
The extent of grasslands has contracted globally, leading to significant declines in grassland-obligate species, including birds. Grassland birds are threatened by multiple factors, including grassland conversion to cropland, and development, including ...

Survival of Postfledging Grassland Birds in Missouri [PDF]

open access: yesThe 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.

Managing urban and rural rights-of-way as potential habitats for grassland birds

open access: yesAvian Conservation and Ecology, 2017
Urban grassy rights-of-way (ROWs) such as along transmission lines could be managed cumulatively as collections of potential grassland habitats to contribute to the conservation of grassland birds.
