Fig 1. Food characterization and preferences among wild pigeons.
A. Density plots of food preferences for individual from the two
studied populations. Food preferences are represented as the fraction of
each food type consumed by an individual during a 20-min trial (N= 158 trials for 42 individuals). Trials for pigeons from MoiĆ are shown
in purple and those from BCN in green. B. Differences in
nutritional and morphological similarity between food type (darker
colors indicate larger differences). C. Characterization of
nutritional and morphological differences between food types.D. Niche position and breadth of the two studied wild
populations (mean and standard error) in the space defined by resource
differences.
Table 1. Repeatability of the niche centre and breadth
in the short and long-term . Repeatability is the intra-class
coefficient of each measure (i.e. phenotypic variation among
individuals/total phenotypic variation). The abbreviations l-95% CI and
u-95% CI refer to the lower and upper 95% credibility interval,
respectively. The long-term assay was conducted one year after the
short-term assay.
