Abstract
Seasonal migration is highly labile from an evolutionary perspective and known to rapidly evolve in response to selective pressures. However, long-distance migratory birds rely partially on innate genetic programs and may be constrained in their ability to alter their migratory behavior. We take advantage of recent advances in our ability to genotype historical DNA samples to examine the temporal stability of migratory connections between breeding and nonbreeding populations (i.e., migratory connectivity) and population-level nonbreeding distributions in the Wilson’s warbler (Cardellina pusilla), a long-distance migratory songbird. By assigning historical and contemporary samples collected across the nonbreeding range to genetically distinct breeding clusters, we suggest that broad-scale population-level nonbreeding distributions within this species have remained largely consistent within Mexico from the mid-1900s to the present day. These findings support the idea that the nonbreeding distributions of long-distance migrants may remain stable over long time scales, even in the face of rapid environmental change.

Description of the data and file structure
Reference_Breeding_WIWA_Rubias_Input.txt
This file contains genotypes at 96 loci for 407 contemporary Wilson’s warblers with known breeding locations taken from Ruegg et al. (2014). These birds served as reference samples when carrying out population assignment with the rubias R package. ‘sample_type’ indicates whether the sample is a reference (i.e., known origin) or mixture (i.e., unknown origin) sample, ‘repunit’ indicates the reporting unit that the individual belongs to, and ‘collection’ indicates the name of the population that the individual is from (for reference samples). Missing data are coded as 0.
Contemporary_WIWA_Rubias_Input.txt
This file contains genotypes at 96 loci for the 131 newly genotyped contemporary Wilson’s warblers collected from 1998-2020 across Mexico and Honduras. This file was read into rubias for population assignment of the contemporary samples. ‘sample_type’ indicates whether the sample is a reference (i.e., known origin) or mixture (i.e., unknown origin) sample. Missing data are coded as NA.
Contemporary_WIWA_Metadata.csv
This file contains metadata for the 131 newly genotyped contemporary Wilson’s warblers collected from 1998-2020 across Mexico and Honduras. ‘State’ refers to the state or department where each individual was sampled.
Historical_WIWA_Rubias_Input.txt
This file contains genotypes at 96 loci for the 49 historical Wilson’s warblers collected across Mexico from 1934-1964. This file was read into rubias for population assignment of the historical samples. ‘sample_type’ indicates whether the sample is a reference (i.e., known origin) or mixture (i.e., unknown origin) sample. Missing data are coded as NA.
Historical_WIWA_Metadata.csv
This file contains metadata for the 49 historical Wilson’s warblers collected across Mexico from 1934-1964. State refers to the state or department where the individual was sampled.
Ruegg-et-al-2014_Contemporary_Assignments.txt
This file contains population assignment information for 239 contemporary Wilson’s warblers from Ruegg et al. (2014) that were sampled across the wintering grounds (Mexico, Nicaragua, El Salvador, Belize, Costa Rica, and Honduras). ‘State’ refers to the state or department where the individual was sampled. For each individual, the file indicates the probability of assignment to the Western Boreal (‘AK2Alberta’), Coastal California (‘CoastalCA’), Eastern (‘Eastern’), Pacific Northwest (‘PacNorthwest’), Basin Rockies (‘RockyMtn’), and California Sierra (‘Sierra’) breeding clusters.
