Across the deserts and sea: inter-individual variation in migration routes of south-central European barn swallows (Hirundo rustica)

Table 1 Number of individuals with complete migration routes according to year (group of columns) and population of origin (rows)

The number of individuals with complete routes during both post- and pre-breeding migrations is reported in brackets. Note that totals per study area do not necessarily correspond to sums of post- and pre-breeding migrations because one GLS can provide complete data for the post-breeding migration route only and another for the pre-breeding route only
