Not at the Mercy of Wind How can insects that migrate high altitudes on fast-moving winds influence their direction migration, when wind speeds typically exceed self-propelled air by a factor three or four? Using automated vertical-looking entomological radar systems, Chapman et al. (p. 682 ) show compass-mediated selection favorable tailwinds, and partial correction for crosswind drift, are widespread phenomena in migrant insect species. Specialized flight behaviors have decisive migration pathways achieved insects. Thus, contrary to popular belief, not mercy wind.
