These data are daily summary checklists of all bird species observed at U.S. Geological Survey, Alaska Science Center (ASC) field camps in Southwest Alaska. Data include species observation details such as observers, dates, location, and number of individuals seen. Included are data from three camps along the Alaska Peninsula, in and around Izembek National Wildlife Refuge ("Izembek NWR", "Cold Bay", and "Neumann Island") during field seasons: 1986-1993.

These data are daily summary checklists of all bird species observed at U.S. Geological Survey, Alaska Science Center (ASC) field camps in the Baja California Peninsula, Mexico. Data include species observation details such as observers, dates, location, and number of individuals seen. Included are data from four camps along the the Baja California Peninsula, Mexico ("San Quintin", "Ojo de Liebre", "San Ignacio", and "Santa Rosalia") during the winter field seasons: 1990-2006.
This dataset includes bird species, invertebrate order and family, sample identification codes, capture date, latitude, longitude, habitat, site name, bird age, total mercury concentrations in bird blood, and methylmercury concentrations in whole body aquatic invertebrates.

These data are daily summary checklists of all bird species observed at U.S. Geological Survey, Alaska Science Center (ASC) field camps in Western Alaska. Data include species observation details such as observers, dates, location, and number of individuals seen. Included are data from three camps along the Kashunuk River within the Yukon Delta National Wildlife Refuge ("Old Chevak", "River Camp", and "Square Bend") during the summer field seasons: 1985-2012.
Individual species often drive habitat restoration action; however, management under this paradigm may negatively affect non-target species. Prioritization frameworks which explicitly consider benefits to target species while minimizing consequences for non-target species may drastically improve management strategies. We examined extents to which conifer removal, an approach frequently implemented to restore sagebrush ecosystems, can be conducted without detrimental effects to conifer-associated species, including the imperiled Pinyon Jay (Gymnorhinus cyanocephalus). Additionally, we predicted abundance responses for multiple species following simulated conifer removal at sites selected to achieve variable management...
Abstracts (from http://digitalcommons.unl.edu/ncfwrustaff/177/): Climate change has increased worldwide temperatures, affected seasonal patterns, and altered important sources of natural selection. To manage wildlife populations successfully, we must understand how patterns and processes of climate change alter trade-offs between sources of selection to predict how individuals may respond, populations may evolve, and management actions may ameliorate the costs of changing climates. Here we discuss how the migratory patterns of leapfrog and chain migration facilitate or constrain responses by migratory songbirds to spatial and temporal variation in climate change across western North America. Based on 52 years of...

Synopsis: This document details the Milk River Basin project, designed to produce innovative approaches to multi-species management in Southern Alberta. The Milk River basin contains a variety of ‘sensitive’, ‘at risk’, and ‘may be at risk’ species. The process of prioritizing the landscape for conservation and stewardship was driven by species inventories to identify known locations, and Habitat Suitability Index (HSI) models to delimit suitable key habitat for the 17 selected species. The construction of the models was limited to the available variables and resolution of the databases. For MULTISAR: the Milk River Basin Project area this was the quarter section, the resolution of the Native Prairie Vegetation...

Terrestrial ecosystems are vulnerable to future changes in the global climate, including increased temperatures, changing precipitation patterns, and changes in vegetation. Information on the potential effects of climate change on bird communities can help guide effective conservation and inform land management decisions. We used output from MC2, a dynamic global vegetation model (DGVM), and climate models to inform the potential distribution of vegetation types based on hybrid vegetation maps dervied from the GAP vegetation classification system. These hybrid vegetation models were then used to inform bird distribution models0. The data covers three time periods (1970-1999), (2035-2064), and (2070-2099) for 59...
A biologist and field crew from Northern Prairie Wildlife Research Center visited sites nine times throughout the breeding season (late May to mid-July) to record counts of grassland birds. Surveyors applied North American Breeding Bird Survey methodology to obtain counts at On-, Near-, and Off-road Stops, but unlike the North American Breeding Bird Survey, which features a single survey at each site, three replicate surveys were conducted on back-to-back-to-back days during each survey period to facilitate estimation of detection and occupancy probabilities. Assignment of surveyors to individual sites followed a design protocol that allows observer effects to also be estimated. The biologist visited each site once...

Northeast Montana represents critical, core breeding habitat for many of our most imperiled grasslandsongbird species. USFWS has been working cross-programmatically and with a broad array of externalpartnerships in this region to maintain and enhance habitat for these species. However, to date we havenot adequately monitored birds response to these interventions to determine if and how much we arebenefiting populations. This project would provide that capability for at least a five-year period.

Synopsis: This study examined the reluctance of different birds species to cross habitat gaps in a fragmented forest landscape. Researchers induced birds in the post-fledging period to cross gaps of varying widths and to choose between routes through woodland or across open areas by attracting them with recorded chickadee mobbing calls. Overall, birds were twice as likely to travel through 50 m of woodland than they were to travel through 50 m of open gap areas to reach the recording. When given a choice of traveling through woodland or across a gap, the majority of birds preferred woodland routes, even when they were three times longer than shortcuts in the open. Birds did not just use movement corridors, but strongly...
