Variable names and
description

specimen: specimen number
in museum collections

scientific.name:
scientific name

common.name: common
name

year: year of
collection

longitude: longitude of collection location

latitude :
latitude of collection location

x: chromatic
coordinate x obtained from visual modelling (relative stimulation of VS vs S
cone)

y: chromatic coordinate y obtained from visual
modelling (relative stimulation of M vs VS+S cone)

z: chromatic coordinate z obtained from visual
modelling (relative stimulation of L vs VS+S+M cone)

PC1: first principal
component summarising variation in xyz chromatic coordinates computed within
each species.

chroma: saturation,
distance from xyz coordinates of measurement to the achromatic centre (xyz
coordinates of a perfectly flat reflectance spectrum).

sens.type: visual
sensitivity type used to compute xyz coordinates, typeV=V-type visual
sensitivities and typeU=U-type visual sensitivities.

irrad.type: type of
light source used in visual modelling (irradiance), where d65=standard
daylight, forestshade= forest shade and woodlandshade= woodland shade.

correct.sens: (yes/no)
whether the visual sensitivity used for visual modelling (“sens.type”) matches
the presumed visual sensitivity type of the species (“visual.system”).

Temp: annual mean
temperature of the collection location in a 50km radius.

Prec: annual precipitation
of the collection location in a 50km radius.

primary.productivity: primary
productivity of the collection location in a 50km radius.

Temp.25: annual mean
temperature of the collection location in a 25km radius.

Prec.25: annual precipitation
of the collection location in a 25km radius.

primary.productivity.25:
primary productivity of the collection location in a 25km radius.

mobility: mobility
score for each species (0-1-2).

carotenoid:
yellow/red, type of carotenoid of plumage patch measured.

visual.system:
presumed visual sensitivity of the species.

plumage.patch: name of
plumage patch measured
