This workflow produces many different datasets, some of which are only intermediate, used in the next of the workflow, and some of which are final, summarized and ready-to-use datasets.

Generally speaking, .rds files (R data file) are used to pass output from one step to another, while preserving variable types (categorical, etc.) as well as nested data (list-columns).

.csv files are used for final outputs, or where the data being passed between steps is smaller and simpler.

.feather files are used for the initial conversion of Motus data stored in SQLite tables to a different format. SQLite data bases are great for quick access, but I found that the more filters and joins and other manipulations I applied, the slower the operations became. I found it easier to convert to feather right at the beginning and then use this format for filtering etc. later on.

Data are stored in the Data folder created by the workflow. This data is too large to be stored on GitHub, so only the workflow scripts and report outputs are online.

Here, we list all the datasets followed by definitions for each variable included.

Data folders

01_Raw - Downloaded or acquired data

  • Motus SQLite databases (project-XXX.motus)
  • TagsSpeciesProject.xlsx from Catherine

02_Datasets - Intermediate data produced by the workflows

  • hits and runs folders - filtered hit and run level data in feather format [Not included in below descriptions]
  • noise_hits.feather & noise_runs.feather - “noisy” runs or hits for later removal [Not included in below descriptions]
  • receivers.csv - List of receivers and whether they overlap with a species eBird range.
  • transitions_intitial.rds & bouts_initial.rds - First pass created transitions and bouts
  • transitions_cleaned.rds & bouts_cleaned.rds - Final pass transitions and bouts (but without complete metadata)
  • stn_dist.rds - Station (groups) distances and minimum flight times
  • bad_bouts.rds - List of bouts identified as being ‘bad’ (false positives) to be filtered [Not included in below descriptions]

03_Final - Final datasets for analysis

  • bouts_final.csv - Bouts of activity detected by a station (group) for each bird over time
  • trans_final.csv - Transitions between stations (groups) for each bird over time
  • bouts_final_split.csv - Same as bouts_final.csv except that bouts which span more than one local day are split at midnight into separate bouts.
  • summary_birds.csv - Summaries of movement and timing for each bird
  • summary_daily_bouts.csv - Daily bouts of activity by a birds at a particular station (group)
  • summary_circadian_bouts.csv - Subset of the split bouts data including only birds who spent a significant amount of time at a single station. Includes start/end variables for plotting circadian rhythms.
  • summary_stopover_days.csv - Subset of the daily bouts data showing birds with possible stopovers, identified by those detected at a station (group) over multiple days during migration.
  • summary_stopover_time.csv - Subset of the daily bouts data showing birds with possible stopovers, identified by those spending time at at a station during migration.
