Summary: The data set consists of behavioral trials from 241 corvid subjects across 10 species and 10 lab teams: common ravens (n=15), carrion crows and carrion/hooded hybrid crows (n=18), large-billed crows (n=13), New Caledonian crows (n=9), ‘Alalā (n=108), Eurasian jays (n=24), pinyon jays (n=21), blue jays (n=9), Clark’s nutcrackers (n=10) and azure-winged magpies (n=14). Each row represents a single trial for a single subject.

R code:
 miller_etal_2021_rcode.R - code for running computations and generating figures

R Markdown documents:
 miller_etal_2021_SM.Rmd - R Markdown document with R code embedded for supplementary materials

Instructions to reproduce results:
 To reproduce these results, first unzip the files into a folder. Then, ensure that a subfolder named "figures" is in the folder. Next, open miller_etal_2021_rcode.R and ensure that all packages mentioned at the top of the script are installed.  Once all packages are installed, run the script in R using 'source("miller_etal_2021_rcode.R")'.

 Once the script runs without errors, you can compile the R Markdown document miller_etal_2021_SM.Rmd.  Open this file in RStudio and ensure that you have packages {knitr} and {rmarkdown} installed.  Once installed, use {knitr} to render the document (control-shift-K).
