R Documentation

Summarized flight height profiles from Johnston et al (2014)

Description

A dataframe containing flight height profiles for all species in Johnston et al. (2014). Values are expressed as the proportion of birds in 1 metre height intervals.

Usage

Johnston_Flight_heights_SOSS

Format

A data frame object with 3 columns containing the maximum likelihood, the median, and Upper/Lower confidence limits of flight height distributions. Flight height bands go from 1 - 300m ASL.

height: Height above sea level, in metres. First element represents the 0-1 meters height band, and height interval is 1 metre.
variable: The species name and variable from Johnston et al 2014 estimates. E.G., ArcticSkua.est is the maximum likelihood estimate from those models. .est = maximum likelihood, .lcl and .ucl are the lower and upper 95% CLs, and .med is the median estimate.
prop: The proportion of birds within the 1m flight height bands.
