babblers: Feeding rates of babblers

In GLMsData: Generalized Linear Model Data Sets

Feeding rates of babblers

Description

The daily individual feeding rates of chestnut-crowned babblers

Usage

data(babblers)

Format

A data frame containing 97 observations with the following 8 variables.

ObsTime

the length of observation (in decimal hours); a numeric vector

Sex

the sex of the bird; one of f (female) or m (male)

Age

the age of non-breeding group members; one of adult or yearling

Relatedness

the pedigree-based relatedness to the brood; one of 0.5 (first-order relatives); 0.25 (second-order relatives) or 0 (more distant relatives)

ChickAge

the age of the brood, in days; a numeric vector

BroodSize

the size of the brood: a numeric vector

UnitSize

the number of individuals in the unit; a numeric vector

FeedingRate

the daily individual feeding rates, in feeds per hour; a numeric vector

Details

The data relate to a population of colour-ringed population of chestnut-crowned babblers in an area of the University of New South Wales Arid Zone Research Station, (Fowlers Gap, western New South Wales, Australia). The study determined whether, where and how often non-breeding group members contributed to providing for nestlings by monitoring the visit rate of tagged birds during 2007 and 2008. These data are extracted from a larger data set, extracted so that there is one (randomly chosen) observation for each individual bird.
