Banding allows identification of individual birds, and many investigators use data from recaptured or recovered birds to infer population parameters, including survival rates, migration rates, and recruitment rates. Such analyses often assume th[...]

Visual estimates of the distribution of the flight heights of birds are often critical for collision risk assessments for wind-energy projects. However, the reliability of such data is largely unknown. The results of trials where rangefinder hei[...]

Little is known about the breeding ecology of Kittlitz's Murrelets (Brachyramphus brevirostris), a species suspected to have experienced both local and regional population declines in recent years. We studied aspects of their breeding ecology on[...]

Sprague's Pipits (Anthus spragueii) are migratory grassland songbirds endemic to North America that have experienced a substantial decline in population over the last half-century. No complete account of their historic wintering range is availab[...]

Obtaining sufficient numbers of detections during point counts to make inferences concerning the presence and abundance of secretive species, such as many species of marsh birds, can be difficult. However, autonomous recording units (ARUs) can p[...]

Efficiency and fitness consequences of two trapping methods for recapturing ground-nesting songbirds
Devin R. de Zwaan, Auteur ;
Sarah A. Trefry, Auteur ;
Kathy Martin, Auteur
Capturing nesting songbirds is a core component of many field studies. However, avoidance of traps and mist-nets by birds can reduce capture efficiency and bias study results, particularly when individuals need to be recaptured multiple times. W[...]

The rate of occupation of territories or nest locations has been proposed as a suitable surrogate of breeding territory/habitat quality when more precise, but costly, measures are not available. However, whether the frequency of breeding territo[...]

Endemic species with distributions restricted to narrow elevational ranges in the Andes are among the least-known tropical birds and are also among the most vulnerable to anthropogenic pressures of climate change and habitat fragmentation. One s[...]

Identifying the threshold of habitat cover beyond which species of birds are locally lost is useful for understanding the biological consequences of landscape changes. However, there is little consensus regarding the impact of landscape changes [...]
