## Initial orientation of displaced homing pigeons

### Description

This data set has 108 rows and 2 columns. The observations are the vanishing bearings of homing pigeons displaced and released at two unfamiliar locations. The data are pooled with respect to the home direction (home direction set in 360 grades).

### Usage

    data(pigeons)

### Format

This data frame contains the following columns:

`treatment`

  , a factor with levels: c, control pigeon (unmanipulated); v1, pigeons subjected to bilateral section of the ophthalmic branch of the trigeminal nerve; on, pigeons subjected to bilateral section of the olfactory nerve

`bearing`

  , vanishing bearing of each bird in degrees
