Description

Data.Alala.carry.txt is a tab-separated file containing raw data for bird carrying behavior.

Column definitions:

  1. Name of each bird
  2. Sex (1 = male; 0 = female)
  3. Plant (scientific name using first three letters of genus and first two letters of species)
  4. Eaten (number of times each bird observed carrying that plant)
  5. Given (number of times each bird given that plant)
  6. Eats (proportion of times each bird observed carrying that plant)
  7. Age (0 = juvenile; 1 = adult)

Data.Alala.eat.txt is a tab-separated file containing raw data for bird eating behavior.

Column definitions:

  2. Sex (1 = male; 0 = female)
  3. Plant (scientific name using first three letters of genus and first two letters of species)
  4. Eaten (number of times each bird observed eating that plant)
  5. Given (number of times each bird given that plant)
  6. Eats (proportion of times each bird observed eating that plant)
  7. Age (0 = juvenile; 1 = adult)

Data.Plant.germ.txt is a tab-separated file containing raw data for bird eating behavior.

Column definitions:

  1. Rep (trial)
  2. Plant (scientific name using first three letters of genus and first two letters of species)
