How climate affects the timing of bird migration is a key question in the study of migratory bird ecology. One of our colleagues, Maggie MacPherson, a PhD candidate at Tulane University, is modeling how Tyrannus flycatchers track rainfall vs. temperature across the Western Hemisphere.

See her website for animated maps showing how Eastern Kingbirds (Tyrannus tyrannus), Tropical Kingbirds (T. melancholicus) and Fork-tailed Flycatchers (T. s. savana) track temperature vs. rainfall throughout the year.
