Migration Influences Survival, Breeding, and Productivity of a Neotropical Migrant

Relationship between westerly wind speed during migration and apparent annual survival of yellow warblers (see Figure 2 from Drake et al. 2014 for details).

Check out this new paper emphasizing the importance of the migratory period on breeding demographics. “We find little evidence that conditions during the wintering period influence breeding phenology and apparent annual survival. Our study emphasizes the importance of climatic conditions experienced by migrants during the migratory period and indicates that geography may play a role in which period most strongly impacts migrant populations.”
