Functional trait table for mixed-species flocking birds in the Western Andes of Colombia

These data represent functional traits relevant to the foraging ecology
and habitat preferences of mixed-species flock joining bird species from
the Western Andes of Colombia. We collected these data based on published
data for the species from the Handbook of the Birds Alive online database
(del Hoyo et al. 2020), supplemented with additional natural history
references were available, with the objective of calculating the
functional richness contained in mixed-species flock compositions sampled
across a patch size gradient of subtropical forest fragments in the
Serriania de los Paraguas, Valle del Cauca department, Colombia. We
tabulated foraging data from 99 bird species observed at least once in a
mixed-species flock, including body mass, nest type and clutch size,
relative use of four different diet categories, use of different
foraging attack maneuvers, foraging substrates, and elevational strata
within the forest. We used these data in Jones and Robinson (2020) to
calculate the Functional Richness and Functional Dispersion indices for
each flock composition.
