bird_create: Create bird flight traits

In Rafnuss/GeoPressureR: Global Positioning by Atmospheric Pressure

Create bird flight traits

Description

This function returns a list with the four morphological information necessary to construct the power curve: mass, wing span, wing aspect ratio, and body frontal area.

When any of these variables are missing, we query the AVONET database using the scientific name from the Clements Checklist.

Usage

bird_create(
  scientific_name,
  mass = NULL,
  wing_span = NULL,
  wing_aspect = NULL,
  wing_area = NULL,
  body_frontal_area = NULL,
  species_name = deprecated()
)

Arguments

scientific_name	Scientific name of the species
mass	Mass of the bird in kilograms
wing_span	Wing span in meters
wing_aspect	Wing aspect ratio (no unit)
wing_area	Wing area in meter square
body_frontal_area	Body frontal area in meter square
species_name	Use scientific_name instead

Value

List containing mass, wing span, wing aspect ratio, and body frontal area.

Examples

# Using AVONET dataset
bird_create("Acrocephalus arundinaceus")

# Using AVONET dataset + custom values
bird_create("Acrocephalus arundinaceus", wing_aspect = 8)

# Import your own bird. You will need mass, and at least two of wing_span,
# wing_aspect or wing_area.
bird_create("Madynuss nutshell", mass = 8, wing_span = 0.2, wing_aspect = 4)
