id: Unique identifier for each provisioning watch
feeds: Number of feeds by each individual per watch
data_type: Whether the data was taken directly from field observation (observed) or from null model randomization (expected)
alt_feeds: Number of alternated visits
percent_alt: Percentage of each carer's visits which were alternated
sync_feeds: Number of synchronized visits (2-minute interval)
percent_sync2mins: Percentage of each carer's visits which were synchronized (2-minute interval)
carer_status: Factor designating whether a carer was a breeding female (female), breeding male (male) or non-breeding helper (helper)
carer_id: The unique identifier for each carer
total_feed_rate: The number of feeds performed by all carers per hour
brood_size: The number of chicks in the brood
carer_number: The number of carers observed provisioning during a given watch
watch_duration_mins: The time, in minutes, between the first and last recorded feed during a given watch
watch_time: Number of hours since the start of the day 00:00 the watch was started
brood_age: The number of days, since recorded hatching, that a watch was performed
julian_hatch_date: The number of days since March 1 each year that the eggs hatched
a_max: The total percentage of visits during a given watch which could theoretically be alternated (or synchronized). Formula as follows: 100 - ((Number of feeds by highest feed rate carer - Number of feeds by all remaining carers)/Total number of feeds)*100
year: Unique identifier for each year the watch was performed during
nest: Unique identifier for each nest
individual_feed_rate: The number of feeds performed by each carer per hour
