Table S1. Results of t- test ( feather, claw
stable hydrogen isotope values, breeding latitude, wintering latitude,
T, fat score, and body mass) comparing resident and migrant juncos.
Results are given as mean ± SEM.
Table S2. List of total 3038 identified proteins and protein
expression as area under the curve for each individual.
Table S3 . List of differentially expressed proteins between
resident and migrant juncos. A protein was categorized as differentially
expressed with threshold of false-discovery rate (FDR) of <
0.05.
Table S4 (a-c). List of significant gene ontology (GO) terms
were extracted from the differentially expressed proteins in resident
and migrant juncos (FDR < 0.05). The list of enriched GO terms
was presented in three functional categories based on the properties of
the identified proteins: (a) biological process (BP), (b) cellular
component (CC), and (c) molecular function (MF).
Figure S1. Left panel: Stacked posterior probability density
maps for feather (top) and claw (bottom) geographic assignments for all
migrant juncos (J. h. hyemalis) individuals (n = 5), with the
isotopic composition of each sample shown in the title of the map.
Middle panel: From these maps, we retained the cells within the top 10%
highest posterior probability for feathers (in yellow) and claws (in
blue) to produce high probability ‘threshold’ maps, with seasonal range
maps shown underneath. Right panel: Histograms represent the range of
possible latitudes for each individual based on the threshold maps, with
median latitude shown in the histogram title.
Figure S2. Left panel: Stacked posterior probability density
maps for feather (top) and claw (bottom) geographic assignments for all
resident juncos (J. h. carolinensis) individuals (n = 5), with
the isotopic composition of each sample shown in the title of the map.
Middle panel: From these maps, we retained the cells within the top 10%
highest posterior probability for feathers (in yellow) and claws (in
blue) to produce high probability ‘threshold’ maps, with seasonal range
maps shown underneath. Right panel: Histograms represent the range of
possible latitudes for each individual based on the threshold maps, with
median latitude shown in the histogram title.
