Data for "Seasonal movements of post-breeding royal terns (Thalasseus maximus) in Virginia"

Royal tern tracking data for analysis in R via the momentumHMM package:*REQUIRES R statistical software which is freely available here: https://cran.r-project.org. The package and data analysis are all within the R statistical framework.For information: [e-mail], reference ROYT tracking project # R version 4.4.1 "Race for your life".These are tracking data collected from ( Royal terns that were nesting on Rip-raps Island. For full description of the model and the package, see the manuscript.Model. We assumed step length at each time step followed a gamma distribution, and we modelled the mean and the standard deviation in step length as a function of period. We assumed that individual turning angles (i.e., short-term persistence in the path of travel) followed a wrapped Cauchy distribution with a mean of 0 (i.e., no change from prior path of travel) and a concentration parameter that was a function of period, where higher concentration values indicate lower variance around the mean (circular-linear regression model, McClintock and Michelot 2018).Also see momentuHMM vignette:https://cran.r-project.org/web/packages/momentuHMM/vignettes/momentuHMM.pdfAlso see:McClintock, BT, T Michelot. 2018. momentuHMM: R package for generalized hidden Markov models of animal movement.
