Human‐scent contamination of bird nests and the human‐made trails leading to them is
suspected to influence nest survival by attracting or deterring predatory mammals. This …

Abstract The Pampas Grasslands in South America have been almost completely
transformed by urbanization and agriculture. Many grassland birds persist only in extensive …

Knowledge of the breeding biology of grassland birds is important given the accelerated rate
of transformation of their habitats, which has led to noticeable population declines of many …

Nest survival is a vital component of breeding success, and affects population dynamics, as
the loss of nests is the main cause of reproductive failure in birds. To identify key factors for …

Proliferation of wind energy across the Great Plains of the United States has the potential to
negatively affect many grassland birds through displacement, avoidance, or changes in …

The accelerated rate of grasslands transformation has led to noticeable population declines
of many grassland bird species. Although several species of the Pampas grasslands are of …

研究活动(如查巢和视频拍摄) 对鸟类巢存活率的影响一直受到关注. 近年来的研究虽然已表明这
种影响较小, 但以往研究多以开放巢或洞巢鸟类为研究对象, 对营球形巢的鸟类研究较少 …

Background Research activities have often been thought to potentially influence avian
nesting success by increasing nest predation rates. Although recent studies of species …

Grassland ecosystems have suffered intense modification worldwide, resulting in a loss of
biodiversity. Birds that breed in grasslands have experienced steep population declines …

Demographic studies of many bird species are challenging because their nests are cryptic,
resulting in few nests being found. To maximize statistical power, methods are needed that …
