Count data for six warbler species in Pennsylvania, USA

Description

Count data on 6 warblers in Pennsylvania, USA in 2018. Data come from the North American Breeding Bird Survey. Data indicate the total numer of individuals for each of 6 species counted at 50 stops along a 40km route (95 routes in the data set). The six species included in the data set are: (1) American Redstart (AMRE); (2) Blackburnian Warbler (BLBW); (3) Black-throated Blue Warbler; (4) Black-throated Green Warbler; (5) Hooded Warbler; and (6) Magnolia Warbler. Covariate data include three bioclimatic variables derived from PRISM. Two landcover variables (forest cover and developed land cover) come from USGS Earth Resources Observation and Science (EROS) Center.

Format

bbsData is a list with three elements:

y: a two-dimensional matrix of count data with rows corresponding to species (6) and columns corresponding to sites (95).

covs: a data frame with 95 rows and 8 columns consisting of covariates for use in modeling relative abundance.

coords: a numeric matrix with 95 rows and two columns containing the site coordinates. The proj4string is "+proj=aea +lat_1=29.5 +lat_2=45.5 +lat_0=37.5 +lon_0=-96 +x_0=0 +y_0=0 +datum=NAD83 +units=m +no_defs"
