Object,Description
y_sum,the summation of the 2 counts per point count location each year; the response variable
point,"GRSP, HOLA, and LARB files only; numeric form of year-pasture-point count location, i.e. 'survey' in the manuscript; unique identifier; used for hierarchical-centering approach for modeling block and pasture random terms "
year,year the point count was conducted
block,the experimental block the pasture was in
dclass,distance class within which an individual bird was detected; distance classes were delinated in bins of 10 m
delta,width of distance class bin - 10 m (input into the model as 0.1 because distances were divided by 100 before being input into the model sensu Kery and Royle 2016)
e,used to calculate a model's Bayesian p-value
maxd,max distance at which a species was detected (multiply by 100 to convert to meters)
mdpts,midpoints of distance bins
n.blocks,number of experimental blocks (10)
nbreaks,number of distance intervals
nobs,number of observations of individuals of a given species
nsurveys,"number of surveys (460 for all species except TBLO, 260 for TBLO because they occurred only on the loamy plains ecological site during the course of our study)"
nyear,number of study years (5)
surveyid,the survey within which a detection of an individual bird occurred
t.tau,"parameter for the half-cauchy prior, used to model a random for year on detection probability"
vor,"standardized VOR, equivalent to VO in the manuscript (the R stands for ""reading"")"
npast,TBLO file only; number of pastures; a random term for pasture instead of block was used in abundance models for TBLO because parameters associated with a random term for block would not converge for this species
past,TBLO file only; numeric form of pasture; a random term for pasture instead of block was used in abundance models for TBLO because parameters associated with a random term for block would not converge for this species
