Data for: Post-migratory nonbreeding movements of birds: a review and case study

Seasonal migrations are fascinating and ecologically important, but many migratory species are declining as climate change and land-use change alter the habitats used by migrants across the annual cycle. While some migratory birds use a single wintering site, others undertake large-scale post-migratory movements during the nonbreeding season. Technological advances that enable tracking individual birds are uncovering more examples of post-migratory nonbreeding movements. Documenting these movements is important for conservation, which requires understanding when and where migrants use habitats throughout their range. Here, we reviewed existing literature and collected information on the post-migratory nonbreeding movements of 92 migratory bird species from 18 orders across six continents. Among these records, the most commonly reported drivers of movements were resource availability and climate. This strong dependence of post-migratory nonbreeding movements on birds’ abiotic and biotic ..., We searched Web of Science and Google Scholar on 10 February 2021 using the following search string: “migrat* AND (*bird* OR avian) AND (*winter* OR nonbreeding OR non-breeding) AND (nomad* OR “*winter* movement*” OR “multiple *winter* sites” OR “between*site movement*” OR \"multiple non*breeding sites\" OR itineran*) AND (geolocat* OR *capture* OR track* OR gps OR MOTUS OR nanotag OR transmitter OR band* OR ring*)”. This string was designed to limit the search to migratory birds only and include known terms to describe post-migratory nonbreeding movements. We did not search for grey literature or use snowballing techniques.,
