A dataset containing distances acorns of two oak species were carried by acorn woodpeckers (Melanerpes formicivorus) to their granaries, in two different years for each oak species. Data were collected in oak savanna habitat in central California. Acorn woodpeckers store acorns in central granaries, and different woodpecker social groups maintain different granaries. The variables are as follows:
Species, the species of oak for the observed acorn ("lobata" for Quercus lobata, "agrifolia" for Quercus agrifolia)
Year, the year of observation (2002 and 2004 for Quercus lobata, 2006 and 2007 for Quercus agrifolia)
Granary, the woodpecker granary from which the acorn was collected
Distance, distance in metres from the acorn source tree to the granary
Data frame with 534 rows and 4 variables.
