Dataset about how coal tits respond to bitter-tasting peanut pieces: eating, hoarding and retrieving

Datasets from the manuscript entitled "To Hoard or not to Hoard: Does a simple decision rule guide hoarding in coal tits (Periparus ater)?"

The dataset "Seed Destinations" contains the number of peanut pieces in different categories organized by which study they came from, which bird, and what the peanut type was. The variables are:

• Experiment: which of the three studies the data came from.
• Type: whether the nuts were soaked in quinine or water.
• Bird: which individual bird these data are from. The same birds were used for the three experiments.
• eaten: how many nuts were completely eaten.
• hoarded: how many nuts were hoarded.
• dropped: how many nuts were left on the ground after they were dropped.
• outof: the total number of nuts taken by the bird to process.
• outofnoteaten: the total number of nuts taken by the bird that were not fully eaten (=outof - eaten).
• outofnotdropped: the total number of nuts taken by the bird that were not dropped, or if they were, they were then picked up and eaten or hoarded (=outof - dropped).
• retrieved: the number of nuts retrieved after hoarding them in the first phase.
• eatenRetr: the number of retrieved nuts that were fully eaten.
• hoardedRetr: the number of retrieved nuts that were rehoarded.
• dropped Retr: the number of retrieved nuts that were dropped, and not picked up again.

The second dataset contains the nibbling times of the different nuts.

The dataset "Nibble times" contains the data from only the second study, and indicates how long birds spent nibbling on any given nut piece. The variables are as in the first dataset, except for:

• Phase: whether it was the Hoarding or Retrieval phase.
• Nibble: time spent nibbling in seconds.
• Fate: whether eaten, hoarded or left after dropping.
