Land Cover Change and the Breeding Bird Survey: Rates of Change in Relation to Roads
… of Interior Fish and Wildlife Service’s Breeding Bird Survey. Reliability of the Breeding Bird Survey data has been criticized due to surveys being conducted along road-side transects. Based on BBS assumptions that land cover is the same adjacent to roads as it is away from roads the …

The Role of Breeding Habitat Loss in the Decline of Eastern Whip-Poor-Will (Antrostomus Vociferus) Populations in Canada
Populations of birds that feed on flying insects (i.e., aerial insectivores) have been declining for several decades in North America, yet the cause of these declines is poorly understood. Among aerial insectivores, Eastern Whip-poor-will (Antrostomus vociferus; “Whip-poor-will”) populations have …

Status and breeding ecology of the loggerhead shrike in Virginia
… are still relatively widespread, Breeding Bird Survey results indicate that breeding population have declined substantially in Virginia and other parts of the species' range. Loggerhead shrikes should be considered for federal threatened status. I studied breeding chronology, …

Assessing the Imprint of Geography, Host Species, Land Cover and Space on the Local Abundance of a Generalist Nest Parasite, the Brown-headed Cowbird
The Brown-headed Cowbird is an obligate nest parasite suspected of causing local population declines in several threatened and endangered passerine species. Much attention has been directed towards uncovering the fundamental factors that affect cowbird abundance; however, no study has evaluated …

Avian population and community dynamics in response to vegetation restoration on reclaimed mine lands in southwest Virginia
… For this nest-site analysis, I focused on 2 bird species common to reclaimed mine lands in southwest Virginia: field sparrows (Spizella pusillia) and indigo buntings (Passerina cyanea). In addition, I assessed bird community attributes in relation to various surface-mine reclamation regimens …

Reproductive success and survival of the Common Grackle in central Illinois
… has historically been one of the most abundant bird species in North America. However, based on North American Breeding Bird Survey data, the global population has exhibited a steady decline of -1.75% per year over the past 50 years and has suffered a cumulative loss of 58%. Understanding why …

Examining Avian Communities in Wetlands at Multiple Spatial Extents
… unclear. My research focuses on how the diverse bird communities that rely on wetlands might be affected by changes to their primary habitat and the surrounding landscape. I utilized data from the North American Breeding Bird Survey (BBS) and the National Land Cover Database (NLCD) to develop a …

'Islands' in an island: multiscale effects of forest fragmentation on lowland forest birds in Taiwan
… and community composition of lowland-forest birds in Taiwan. At a regional scale, Island Biogeography Theory was applied to examine area and isolation effects on species richness of lowland-forest birds using bird data derived from Breeding Bird Survey Taiwan in 2009 and 2010. I also …

The Effects of Global Change on Avian Biodiversity
… differences in reporting rates across eBird and the North American Breeding Bird Survey (BBS) and assessed the sources of these biases to understand how each dataset can best be used to monitor bird populations. While more species are reported to eBird, there are generally lower counts …

Evaluating Population-Habitat Relationships of Forest Breeding Birds at Multiple Spatial and Temporal Scales Using Forest Inventory and Analysis Data
… studies have documented declines of forest breeding birds in the eastern United States, but the temporal and spatial scales of most studies limit inference regarding large scale bird-habitat trends. A potential solution to this challenge is integrating existing long-term datasets such as the …
