From: Songbirds initiate migratory flights synchronously relative to civil dusk
Net displacement (km) towards the migratory destination by time since departing wintering (beige) or breeding sites (blue) for species likely initiating long-distance migratory flights at departure (Panel A) and species likely first making regional flights after departure (Panel B). Quebec-breeding Swainson’s Thrush and Gambel’s White-crowned Sparrows are not shown because we did not have enough post-departure detection data to make conclusions about their likely post-departure movement type
