Avian Point-Count Data from Boreal Alaska and Maps of Predicted Population Density for Lesser Yellowlegs, Olive-sided Flycatcher, and Rusty Blackbird, 2001-2020

This data package contains 1) field data and 2) predicted distributions of three species of boreal-nesting birds in interior Alaska: Lesser Yellowlegs (Tringa flavipes), Olive-sided Flycatcher (Contopus cooperi), and Rusty Blackbird (Euphagus carolinus). The data are compiled from several monitoring programs: Alaska Landbird Monitoring Survey, Alaska Off-road Point-count Program, Susitna-Watana Hydroelectric Project, Tetlin Forest Inventory Analysis, and surveys on Department of Defense lands by the U.S. Fish and Wildlife Service. Each program conducted avian point-count surveys in some or all years (2001-2020) at locations in Alaska. This dataset includes only the locations within Bird Conservation Region 4 (BCR4; Bird Studies Canada and NABCI 2014) and south-central Alaska. The dataset includes a number of remotely-sensed covariates that were compiled from other sources for the survey locations (Alaska Department of Transportation 2018, Alaska Wildland Fire Coordinating Group 2020, Alaska Center for Conservation Science 2017, Porter et al. 2018, PRISM Climate Group 2018a,b). The data package also includes shapefiles showing the predicted population density of each species across BCR4 in Alaska, where predictions were developed by relating observations to covariates to estimate density and then predicting density based on values of covariates across the landscape; and shapefiles delineating hotspots for each species, where a hotspot is defined as a grid cell whose mean predicted density exceeds the means of 90% of other grid cells in BCR4.
